STM32 timer triggers ADC multi-channel continuous sampling, and DMA caches the results
The ADC of STM32 is very flexible. In terms of sampling trigger, it supports not only software trigger, timer or other hardware circuit automatic trigger, but also automatic trigger of the next channel / round conversion after conversion. Storage of conversion results: it supports not only software reading and transfer, but also DMA automatic s ...

Sampling design of ePWM triggered ADC based on 28035
preface
Jiudao is working on a switching power supply project recently. It needs TI's TMS320F28035 chip to realize the design of control circuit. In short, 28035 is used to collect the semaphore, calculate the algorithm, obtain the duty cycle, and then use the ePWM module to output PWM wave to control the on and off of the power switch, so ...

STM8 MCU ADC single scan mode
when the STM8 single chip microcomputer uses the ADC function to read the values of multiple channels, it can use the single mode. After sampling one channel, reinitialize the other channel, and then sample. After sampling, continue to reinitialize and switch to the next channel. But this sampling is too troublesome. STM8 single ch ...
