Hi all!
I had just installed Klipper fluidd and I tried to heat the bed and noticed both of the temperature readings were at 0 degrees, When i heated the bed i got this error: "Heater heater_bed not heating at expected rate
See the ‘verify_heater’ section in docs/Config_Reference.md
for the parameters that control this check.

Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown"

How can I resolve this?
Help would be much appreciated!

AFAIK Klipper does not support the N32 boards.
Maybe @SteveGotthardt can comment

I have not worked on any N32 based boards; just the H32; a very different mcu. The firmware for HC32F460 is not compatible with N32 based processors.

If the heater doesn’t work it may be the wrong pin in config or the N32 does port setup differently?

Stas2z created a fork with the ADC changes for N32 implemented as a bunch of ifdefs but considers it a one-off workaround and isn’t sure how to get it integrated upstream:

and multiple people have successfully used it:

Is there an official way to request / bounty for the change to be adapted into Klipper?

Ask Stas2z to create a “Pull Request” against official Klipper Github

They previously stated skepticism about getting it to an acceptable state for upstream integration:

No, cuz its a workaround only, mostly it compiles as for stm32f103, but with different code for adc. Pushing it into upstream requires too much time to spend.

but didn’t express what the obstacles are. Any recommendations on re-posting in Features or asking in this PR already dealing with STM32 ADCs?
