Hi all, Im working on firmware for my v2.4 got everything working and am now running into an ADC out of range error, Its normally just a broken thermister or wire but I don’t think that it is. I have a phetus dragon using a NTC100K hooked up to an SB2209(STM32). I think the issue may be I don’t have the SB2209(STM32) configured for the NTC 100K as the NTC 100K is less common but I can’t find anything on it. Any help is appreciated.

Seems your chamber sensor is causing the shutdown

Thanks for the reply, I am still kindof puzzled as to why it is causing issues. It is plugged in but with only one wire not two. I am building from the MPX kit. Attached is the diagram of how it is meant to be

I have no idea what you are trying to achieve, but it does not seem correct and the wrong readings apparently proves this.

I’d just connect this thermistor to the dedicated port on the M8P and check if you get valid readings. Then you can work from there.
