The ADC on the STM32F103 is a 12-bit ADC meaning it has the ability to detect 4096(2^12) discrete analog levels (which is also called Resolution). STM32F103, Having trouble nesting interrupts. Each digital sample should be saved to make a pack or an array of digital samples. Select the ADC channel using ADC->SQR3 : SQ1 bits (1st conversion in regular sequence) Enable EOC interrupt using ADC->CR1 : EOCIE bit. For example, when prescaler = 47, counter clock is 1MHz. The Part 1 article reviewed the history of thermocouple technology and the principal of the operation. I also tried to change the Timer 2 interrupt rate by increasing. This video covers the basics of PWM, and how to implement it with STM32. based on the STM32H743ZI datasheet, the Rin (ADC input impedance) =max 50Kohm and Cadc (internal sampling and hold capacitor) = 4pF. May 19, 2015. In this section we will configure the timer that will be used to trigger the ADC conversions per the following: PWM generation, no output needed since timer is triggering ADC internally.
