I have to do course design this semester, but unfortunately I really don’t understand it. RT, please teach me with your love.
The topics are as follows:
The CPU core chip is ARM7 's LPC2138
1.Use the
1.STM32F103 first powered on 2406 and then 485, the communication was normal2.2406 is powered on first. When STM32F103 is powered on, it will automatically send data to 2406 (it seems that this happen
Now I have made something, and there is a control signal that needs about 30V, so I used 555 to make a three-stage voltage doubler, but did not do isolation, just connected 10u and 100p capacitors to
Still PIC12F1572, a certain io outputs a pulse signal. When io is set high or low, the data is immediately sent to the register, and the level takes 16us to change. The internal clock used, according
