Hi all

When no monitor is connected, and the Wifi link is turned off, then the only sign of life is the heartbeat.
I noticed different rates of blinking and when for some reason my program stops, the heartbeat disappears altogether. Yet I can CTRl C to get the prompt if I reconnect the monitor.

Can someone please explain the logic behind the heartbeat, as to what slows it and when/why does it stop.

Regards

Hi All

I guess no-one can help on that, so...

The next question is, using the on board led for my own version of heartbeat.
But, when I disable the heartbeat (and that works) and try to use GP25 I get errors.

[54] SetPin gp25,dout
Error : Pin 43/R: is invalid

Reading posts from about a year ago showed someone using the on board led.
Has something changed in the later versions ?

That works on the other Picos but on the WebMite I think GP25 goes to the WiFi module. The heartbeat led is connected the WiFi module, so ON/OFF are the only options.

From the manual

Quote Unlike the original Raspberry Pi Pico, the on-board LED on Pico W is not connected to a pin on RP2040, but instead to a GPIO pin on the wireless chip and cannot be accessed from a BASIC program.

The heartbeat can be turned on/off but not otherwise controlled in Basic.

It beats slowly when not connected and then faster when connected to the network. This was done to make it easier to diagnose headless installations.

GP25 is only available in standard and VGA picomites

The heartbeat is controlled by one of the system timers so if the heartbeat has stopped, one of the timers has stopped. RTC and settick etc will also have stopped.

Hi All

Thanks for that, I can stop trying to make my own work.
One problem I have is that the program is still under the impression that it is sending to the Rpi-Zero, but the Rpi-Zero is not receiving anything.
And you guessed it, the Heartbeat light was stopped.

Hi All

I feel the goal posts moving

Installed the latest Beta WebmiteV5.08.00b4.uf2

Now I get errors I didn't previously.

> option rtc enable
Error : Invalid Option

[52] SetPin GP18,CIN 'we are counting Amp Hour pulses
Error : Invalid configuration

Yet
SetPin GP22,CIN doesn't create an error
