I'm using the STM32F042C6T6 processor as nodes in a CAN bus. Each are attached to aMCP2551T-E/SN CAN transceiver. For the firmware, I am using the HAL drivers provided by ST to transmit/receiveCAN frames. Communic...

I have the ADC reading the voltage drop across a 10k thermistor setup in a voltage divider w/ a 57k resistor. If I probe the board itself I can easily read the voltage drop across the thermistor and to the appropr...
Posted on June 11, 2015 at 16:20Sorry for the delayed response. Using a AAA battery I found lying around (discharged, reading 1.21V) I hooked it up directly to the STM32 pins. The reading I am seeing is 1440, so around 1.16V. Still lower, but not by...
Posted on June 09, 2015 at 21:27Ah, I see.The value from the ADC would be 0-4095 and reference voltage is 3.3V. So the voltage I calculate is: ADC_value*(3.3/4096).
Posted on June 09, 2015 at 19:50What do you mean by that? The ADC measurement is read and then communicated over CAN, using the STM32's built-in CAN interface.
