Help!!!!! Chip is stm32f103rct6
I will use stm32cubemx pa8 set to low level, pa9 set to high level (because I am using the chip when pa8 0 led lit up, so I can sure is 0 pa8), but after I use dupont line leads to received motor car tire, do not reflect,
Want to know what the problem is

CodePudding user response:

Description is not very clear, may is that MCU pin drive ability is not enough

CodePudding user response:

This is not feasible, want to drive motor must have driven circuit, microcontroller pins data current but dozens of ma
You do this can't be implemented

CodePudding user response:

refer to the second floor water 枂 reply:

Thank you, it is for this reason, solved

CodePudding user response:

Current is very small only a few of MCU pin ma, can't make the motor work
