Perhaps the problem is the IF statement--counting as perhaps either 1 or 2 statements depending on the form of the condition.

> list
On error skip 1
i%=(s$=1%)
If MM.Errno Then Print "error: ";MM.Errno;" ";MM.ErrMsg$; " i%=";i%
Print "Done"
> run

karlelch said I am experiencing trouble with the latest beta version (5.07.08b11) of the WebMite. I am aware that ideally, I post a short example here, however, I did not yet have time to search for the specific error condition with a respective code snippet. Hence, my question is more if anyone else experienced stability issues with that beta version.

My code can be found here on GitHub.

' - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
' MQTT-related routines
'
Sub StartMQTT restart
' (Re)connect to MQTT server
Print Choice(restart, "Restart", "Start") +" MQTT client ..."
On Error Skip 1
WEB MQTT Close
On Error Skip 1
WEB MQTT Connect MQTT_ADDR$, MQTT_PORT, MQTT_USER$, MQTT_PW$, cb_MQTT
Local integer errno = MM.Errno
If errno = 16 Then
Print "Error (" +Str$(errno) +"): Not connected?"
_doReboot
EndIf
WEB MQTT Subscribe TOP_SOL_PAN
round = 0
tLastMsg_s = Timer /1000
Print "-> done."
End Sub

I'm not able to provide specific help unfortunately but some observations which may trigger some thoughts.

5.07.08b11 has TCP and UDP functionality added. In my attempts to use the TCP client I had a situation where the status messages were causing some strange behaviour with Exit Sub where no error trapping was being done. I have a

CallSubRoutine

Do
'Nothing
Loop

SomeMoreSubRoutines

structure and I was experiencing program aborts back to console on the Loop terminator when I Sub Exit'ed

CallSubRoutine
ON ERROR SKIP
If MM.ErrNo Then Print "...": Sub Exit
...
End Sub

changing this to

CallSubRoutine
ON ERROR SKIP
If MM.ErrNo Then
Close TCP Client
Sub Exit
EndIf
...
End Sub

seemed to make things better behaved.

Maybe there are some MQTT status messages floating around?

I'm also curious as to where you found out that MM.ErrNo = 16 is a failed connection. I was seeing the same 16 in the failed TCP Client. Where did you find an MM.Errno list for the Webmite? I have only seen one for one of the other incarnations of MMBASIC and there 16 was unrelated to TCP as I recall.

If you have not tried Wireshark then I would suggest you give it a try and see what is happening. I found it invaluable resolving some of the ModBus TCP issues I was having.

Best of luck

Cheers
Carl

You have the order wrong.
SUB EXIT should be EXIT SUB

play with the SKIP number and IF condition.

Calls to SUBs and the return are counted as far as ON ERROR SKIP is concerned.
IF is counted but ENDIF is only counted if the condition was true.

One at a time is easier.

That does make it a lot clearer but hasn't helped my confidence.

I shall store this away somewhere as a reference document.

Help please...

I'm trying to setup a single ADC channel on GP26.

I'm using the following configuration per my understanding of the manual

SetPin GP26, AIN 'single ADC channel
SetPin GP27, DIN 'used for PULSIN
DIM ADCOutput!(10) ' take 10 samples
ADC OPEN 250000,1,ADCComplete 'eventually 2 ADC so total still 500kHz

ADC START ADCOutput!() ' called from inside a 10s Tick subroutine

Sub ADCComplete
ADCVoltage=Pin(GP26)
Print ADCVoltage;" Volts"
End Sub

I'm getting this error message on the console

[43] ADCVoltage=Pin(GP26)
Error : Pin 31/GP26 is not an input

What am I missing in setting up the ADC on GP26? Is there some rule about mixed use of the ADC pins, if 1 is declared then they're all declared for ADC? How can an Analog Input declared pin not be an Input? I've checked that there are no other GP26 declarations.

I notice in the v3 manual for the WebMite, Page 61, reference is made to 4 ADC channels, using GP26, GP27, GP28 and GP29. Given that the Pico W only has GP26, GP27 & GP28, I take it this is a typo/carry over from one of the other Mites' manuals.

Thanks

You have to do ADC CLOSE before the pin is available for normal use

SUB ADCComplete
ADC CLOSE
SETPIN GP26, AIN
ADCVoltage=PIN(GP26)
PRINT ADCVoltage;" Volts"
END SUB

It would be better to ask these questions in a separate thread instead of cluttering up the beta announcements.

Not sure where I found that; must have been here in the forum - maybe when WiFi functionality was introduced - because I also did not find it in the manuals.

Thanks Jim. I see it has to be opened again for the next conversion. Changed code to this to make it "free running"

SUB ADCComplete
ADC CLOSE
SETPIN GP26, AIN
ADCVoltage=PIN(GP26)
PRINT ADCVoltage;" Volts"
ADC OPEN 250000,1,ADCComplete
END SUB

Not sure how elegant this is but it's working for now.

Noted and thanks for the heads up. Very new to this , so learning curve and all that.

I note that there is no specific WebMite Topic unless I've missed it?

Many thanks

Hi there

There appears to be a problem with Pin(temp) on 5.07.0811 which is not present on 5.07.07.

Die temp reported by Pin(temp) on 5.07.07 is rational 29ºC. (Different board PicoW - No ADC running)

Die temp reported on Pin(temp) on 5.07.0811 is irrational 87ºC.(Different Board PicoWH - ADC running)

A bit of research indicates the problem is linked to running the ADC, but caused by outdated pi-sdk/build versions and has been around since early 2021.

https://forums.raspberrypi.com/viewtopic.php?t=303013

Hope this helps

Don't understand what you mean. Are you saying that PIN(TEMP) when you have ADC START operational gives the wrong answer? If so then the answer is of course and perhaps I should block it. If not, please explain

Hi Peter

matherp said Don't understand what you mean. Are you saying that PIN(TEMP) when you have ADC START operational gives the wrong answer? If so then the answer is of course and perhaps I should block it. If not, please explain

I have two Pico boards, one with headers, Pico WH, and the other without headers, Pico W.

The Pico WH board is running Webmite 5.07.0811 while the Pico W board is running 5.07.07.

On the Pico W board running 5.07.07 I have not used the ADC assocuiated with GP26-G28.

On the Pico WH board running 5.07.0811 I have configured GP26-GP28 as ADC inputs. Ultimately GP26 and GP27 will measure temperatures using PT1000 and GP28 will measure the grounded input's noise. Although so far I notice it is less than 1 lsb.

In reading this thread I came across the use of Pin(temp) to read the die temperature of the RP2040.

Reading Pin(temp) on the Pico WH 5.07.0811 yields an irrational temperature value of 87ºC and remains at that level no matter the time between reads. On the Pico W running 5.07.07 the temperature is a more rational 29ºC. The temperature readings issue is not about accuracy of the reading but about the incorrect reading, specifically when the ADC start is active, or so I thought.

I did some googling and came out at this link https://forums.raspberrypi.com/viewtopic.php?t=303013 which provided some insight into what I was experiencing. At least in this thread they discounted it being a hardware issue and identified that the issue was removed when using updated Pico-SDK and other later git pulls.

Given that the ADC start could be causing the problem I changed the code to stop the ADC and then get the Pin(temp) and then start the ADC again. This however did not solve the problem. I tried commenting out all the ADC commands but this did not solve the problem either.

It looks like this comment from the link above might be relevant.

Quote Re: ADC internal temp reading + ADC reading
Mon Feb 08, 2021 9:18 pm

Seems to vary on which uf2 was installed, pre-built or which git clone / Pico-SDK has been used to build it, but I would need to be more methodical in identifying which works, what doesn't.

All I can say is that I installed a different .uf2 and the issue went away.

That may explain why some people are seeing problems while some people may not.

It probably also means it falls into the "Report it to MicoPython forum" category.

and

Quote So, this looks to have been a MicroPython / Pico-SDK bug which had been fixed, but people weren't aware of the issue, nor the fix, nor that it had been fixed, nor knew they needed to upgrade, wouldn't have known they had to, and aren't exactly sure how they should.

So from the above perhaps a note that Pin(temp) may not work in 5.07.0811. Perhaps at the next build the updated components will solve the problem...

As far as blocking it is concerned I believe it is a nice feature to have and would advocate for its retention..

Hope this provides the clarity requested.

@Carl,
I have used PIN(TEMP) on 3 different boards all running V5.07.08b11 and all give reliable sensible answers.

If you proved some short run-able code that demonstrates the issue, I will try it here.

Hi there

So after the exhaustive tests below my statement above about the difference between the stable vs beta firmware is inaccurate. It would appear that they both suffer from the same issue...

Decided to hone in further given the reset option

SetPin GP26, AIN
Dim ADC1!(10)
ADC open 166666,1,ADCComplete
'ADC START ADC1!()

Do
Print "CPUTemp "; Pin(temp)
Pause 1000
Loop

Sub ADCComplete
Print "ADCOutput "; Math(MEAN ADC1!())
ADC CLOSE
Pause 1000
Print "CPUTemp "; Pin(temp)
Pause 1000
ADC OPEN 166666,1,ADCComplete
ADC START ADC1!()
End Sub

Console output on Pico WH running 5.07.0811

CPUTemp 32.65732931

And with the ADC START ADC1!()active

> list
SetPin GP26, AIN
Dim ADC1!(10)
ADC open 166666,1,ADCComplete
ADC START ADC1!()

Do
Print "CPUTemp "; Pin(temp)

Loop

Sub ADCComplete
Print "ADCOutput "; Math(MEAN ADC1!())
ADC CLOSE
Pause 1000
Print "CPUTemp "; Pin(temp)
Pause 1000
ADC OPEN 166666,1,ADCComplete
ADC START ADC1!()
End Sub

On console

CPUTemp 91.18876494
ADCOutput 0.2315750916
CPUTemp 98.21253722
ADCOutput 0.2841025641
CPUTemp 98.21253722
ADCOutput 0.2888644689

I had a glipsie when transferring the .bas from the one to the other with TFTP which introduced a power cycle, which then got me thinking and produced the later sets of outputs.

So it looks like the ADC hardware settings are remembered and you have to do a power cycle/reset to clear them...?

But the pin(temp) definitely gives strange values when the ADC is configured on both the 5.07.07 and the 5.07.0811 firmware versions.I also tried doing a reset to the ADC CLOSE included code run and it still gives the strange temperature values.

With the last two runs it is clearly the ADC START ADC1!() which triggers the strange pin(temp) readings. ADC CLOSE does not make pin(temp) work correctly, even through a reset.

Hope this helps.

I can confirm that there seems to be a problem.

DIM ADC1!(1000)
ADC OPEN 166666,2,ADCComplete
'ADC START ADC1!()
DO
n = n + 1
PRINT n;" CPUTemp "; INT(PIN(temp))
PAUSE 1000
IF n = 10 THEN ADC START ADC1!()
LOOP UNTIL n > 40

SUB ADCComplete
ADC CLOSE
k = k + 1
IF k < 50 THEN
ADC OPEN 166666,2,ADCComplete
ADC START ADC1!()
PRINT ".";
ENDIF
END SUB

Run after a reset:

1 CPUTemp 27
2 CPUTemp 27
3 CPUTemp 27
4 CPUTemp 27
5 CPUTemp 27
6 CPUTemp 27
7 CPUTemp 27
8 CPUTemp 27
9 CPUTemp 27
10 CPUTemp 27
11 CPUTemp 84
................................................. 12 CPUTemp 95
13 CPUTemp 86
14 CPUTemp 86
15 CPUTemp 86
16 CPUTemp 86
17 CPUTemp 86
18 CPUTemp 86
19 CPUTemp 86
20 CPUTemp 86
21 CPUTemp 86
22 CPUTemp 86
23 CPUTemp 86

The reported temperature then stay high until the next reset.

Same on a standard picomite

Yes, also on b9, both WebMite and standard.
No program needed, same thing happens at the command prompt.
Only CPU Restart returns it to normal.

It also does bad things to AIN, not just ADC command.
