I am learning microcontrollers. The book says: The operand after push can only be a direct addressing method, such as: push 30H push ACC. It also says: push A is wrong, that is, the operand cannot be ...
Hello everyone, I want to use 51 MCU as the lower computer, and then use VB to write the upper computer, and then use the Bluetooth module to transmit the data of the MCU to the computer. I don’t know...
I need to switch the AD conversion channel in the AD interrupt, but the AD conversion data obtained when switching the channel in AD is abnormal; Phenomenon 1: 1. If I only turn on one AD conversion c...
Use epwm to trigger adc conversion and start DMA transmission. Because I only collect data from A0, I transfer 1 data at a time and wait for the epwm signal. Each time an epwm signal comes, I transfer...
Hello everyone, I am a newly employed electronic engineer. Since I have little experience and just graduated, I am unfamiliar with many things. I am not familiar with them. I am facing difficulties at...
