Mini5+ "mcu-temp" sensor definition does not work

[oc_geek]

; Define MCU sensors which will be available in DWC Extra View
M308 S3 A"MCU" Y"mcu-temp"
M308 S4 A"Duet Drivers" Y"drivers"

For some reason the M308 "mcu-temp" doesn't work - error sensor "mcutemp" does not exist (and yes the "-" is removed in the error message)
(The drivers one perfectly works)

Any help please ?
Does the Mini5+ use a different name for the MCU Temp Sensor ?
(i saw this same command in the Wiki)

Thanks

Can you send M122 and report the results? Should be running fw 3.2 final.

[oc_geek]

Yes i'm on Rel 3.2

Here is the dump of M122

@oc_geek said in Mini5+ "mcu-temp" sensor definition does not work:

Does the Mini5+ use a different name for the MCU Temp Sensor ?

Unfortunately the SAME54P20A chip used in the Duet 3 Mini does not have a functioning temperature sensor. In theory it does have an on-chip temperature sensor, but the errata document for the chip says it doesn't work. Microchip has told me that they don't expect to fix this in a new revision of the chip any time soon.

[oc_geek]

ok that explains a lot, thanks !

Perhaps worth to mention it in the docs so others will know as well

[Phaedrux]

I'll add a note to the documentation.
