Quote Is there a possibility to use a 64bit variable for the maximum number of samples

No the silicon only allows 32-bits. You can use &HFFFFFFFF.
The report from the RXC pointer is just read from the register so is presumably what the silicon does - inc then stop

Not really...

[300] PIO DMA RX 1,0,&hFFFFFFFF,packed%(),ReadyInt,32,samples% 'start DMA ring bf
Error : -1 is invalid (valid is 0 to 2147483647)

V5.07.07b11 - specially for Volhout

https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip

New capabilities for PEEK function
peek(bp n%) ' returns the byte at address n% and increments n% to point to the next byte
peek(sp n%) ' returns the short at address n% and increments n% to point to the next short
peek(wp n%) ' returns the word at address n% and increments n% to point to the next word

These make it very efficient for basic code to step through a packed array

e.g.

dim s$="123456"
a%=peek(varaddr s$)+1 'point to the start of the string data
for i%=1 to 6
print peek(bp a%)
next i%

PIO DMA TX and PIO DMA RX now allow up to &HFFFFFFFF transfers

Gentlemen and Matherp

I am new to this forum and have encountered something strange after version V5.07.07b5.
I am using self-compiled code partly from this forum for an i2c scanner which worked well until V5.07.07b5 and after V5.07.07b7 it stops working and stops at I2C Read i,0,1,temp. Error : Cannot find Temp. And system crashes and ** Fatal Error **

What am I doing wrong or has something changed in the firmware?

Sorry for Dutch.
I translate most of the time because my English is not very good and "Translate" is my best friend and the actual code is English.
For example, I translated the PicoMite Basic manual into Dutch for myself with many examples and additions. (>360 pages so far) and also the PIO course by Volhout (172 pages)

Welcome to the forum.
Your English is much better than my Dutch!

You need to define the temp variable before using it.

dim temp

After that, your code runs on the latest beta firmware.

This happens after running Volhout's Logic Analyzer.

>files
Error : Not enough memory
> option list

The same as Volhout also pointed out in an earlier post. Was this something that you also wanted to address in the latest update?

I just updated the firmware to the latest version (Option list says b12; download says b11).

Jim,

I tried with Dim temp and the first time it worked, but by re-running several times I get an error and reset the program and even ** panic **
Edit no longer works. Can only be fixed by re-flashing program, but problem in firmware is still present.
Previously temp was probably automatically declared?

What happens if you go back to an old MMBasic?

Does it then work?

John,

See my first post. With PicoMite MMBasic version V5.07.07b5 everything worked fine. Then the problems started.
Raspberry Pi Pico is my first microcontroller with MMBasic and have been using it for a year now.

Hi Peter,
I think I've found a difference between the B14 and the B10. I haven't tried
all GP IOs yet, but in the V14 the current is too small to drive an LED (GP09).
In B10 everything goes wonderfully.
Is the current normally set to 4mA?
I use such a LowCurrent LED (1-2mA)!

Or is the error again between Monitor and chair.

Cheers Thomas

P.S. It is : PicoMiteV5.07.07b14 - 06.02.2023 10:34

Thomas, there has been no change in this area so don't know why there would be a difference. Even if the drive strength was only set to 4mA that should be plenty for your LED. I'll test with my LEDs later today.

Interestingly, b14 throws an error on

SetPin gp1, gp0, com1 'define PCR-comm pins
Open "com1:9600,256,ser_int2,1" As pcr_chan

[305] Open "com1:9600,256,ser_int2,1" As pcr_chan
Error : Pins not set for COM1

Has something changed in respect to setpin statement? It works that way in b8 but i have no versions in between to check any further.

Regards,
Gerald

Hi Peter,

Tested picomite VGA 50707b14.

I had several unexplained problems with the latest version. Sometimes I could not edit after stopping the program with ctrl C, sometimes a "out of memory" erro message.
Anyway, with b14 this all stopped. Thanks for fixing this. I have not seenany of these artefacts since. I blaimed myself for being so anoying brining up several issues that where actually my own fault that I did not mention these (felt ashame).

But now we are at it, there is one thing you could give you opinion on.

When I run the logic analyzer code at 126MHz CPU the PS2 keyboard is misreading keys sometimes (i.e. you press a cursor key, and the key value is that of nummber key "4". I know the CPU is busy running MMBasic, graphics, some PIO, DMA etc... So it is possible the system is too busy. But the USB (serial terminal) does not make these false key readings.

When I run CPU at 252MHz this does not happen.

I am currently trying to make the LA work with 126MHz since I hear that some people have problems running new pico's at 200MHz or higher.

Is the keyboard issue caused by the PS2 interrupt priority changed ?

Regards,

Volhout

Hi Peter,

I tested I2C with V5.07.07b14 with the i2c_scanner.bas and it works fine now and also works with the i2c_lcd_lib.bas (This is a lib for 16x2 and 20x4 lcd screens).
I have tested I2C with V5.07.07a3 with the i2c_scanner.bas and now works fine and also works with the i2c_lcd_lib.bas.

@Phil99:

that is really strange ... retested the setpin issue. Cleared flash with clear_flash.uf2, reloaded b14 and did not set any options just to be sure, but got the same error. Is there anything else I can "reset/clear/erase" which may cause the issue?

Regards,
Gerald

Please check if this fixes the issue and then I'll issue a new release - I think the problem was a non-initialised area of memory following the changes I made to the memory handling. Would only happen before a program was run.
