Because of a small problem, it took a long time to record it.
stm32 multiple adc cores use timer trigger, data is only updated once in dma mode
HAL_ADC_ConvCpltCallback also only enters once
ADC is se...
The examples are basically copied from the official perpetual calendar algorithm, and I haven't studied it in depth. The main reason is that the competition requires the use of DS1302. If I use STM32,...
Hello everyone: I have encountered a difficult problem: 283335 is used as a slave to communicate with AM335X. It is found that no matter the query mode, FIFO, or non-FIFO interrupt, it does not work. ...
