Posted on May 11, 2013 at 19:44hi , I have a question , when I calculate the temperature with this code using the formulate in the data sheet:val_adc=ADC_GetConversionValue(ADC1); vsense=(val_adc*Vref)/0xfff;val_adc=(vsense/Avg_Slope)-273.15;in the...
Posted on May 11, 2013 at 10:46 I've been trying for a week now, but I can't seem to read the status of the GPIO ports of the STM32F103RB. can turn LED's on, and transmit CAN, but really struggling to see what the issue is with this one. newish ...
