Martin PelletierI used the uart (DIN,DOUT) on the mDot at 38400baud in order to communicate with another processor.
When i put my interface board on the frozen around -20°C, the mDot generates a checksum error on my uart port!! But as soon as i remove it on the frozen, after 20 minutes it begins to work well!! Then i suspect the crystal drifting the frequency operation which affects the baudrate!!
Do you have any idea about it??
Thx!
Martin PelletierI found my problem 🙂 The mdot was not concerned!!!
The mdot works good under -20°C
