1. When using 11 CANs to send and receive data, the program simulation shows that the data has been sent, but the CAN analysis tool shows that data is lost, and the receiving end does not receive the ...
I would like to ask if the STM8S model with RWW function will not stop interrupts or stop program execution when writing to the internal EEPROM?I am still confused after reading the manual.Thank you!...
I am a sophomore. Apart from the basic courses, my major only offers basic circuit analysis courses. I am not bad at C language and know a little about single-chip microcomputers. I am currently worki...
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
