When operating the spi function of SSP, I found the following statement in lpc1100.h in the example program.
#define IOCON_SCKLOC (*(volatile unsigned long *)(IOCON_BASE + 0x110))
That is to say, the
I used STM32CUBE to develop an experimental program for STM32G431. I felt that the setting was 1K Hz, and the TIM6 clock was very slow. About 50 interrupt cycles, that is, 1S, was 10 times slower. Bec
I want to use AHB mode and GPIO register mapping to turn on the light. Which registers do I need to configure? (I am using arm cortex M3 LM3S9B96) I configured the following, but it does not work. Is
In Keil compilation environment, in main, besides the initialization statement, there is only one loop: unsigned char i; for(i=0;i<10;i++) {Serial_One_SendData(i); } It should loop 10 times, and outpu
Yesterday I helped a friend write something. It was my first time using Zhifeng. I accidentally locked the crystal oscillator of M8 to an external clock, and I couldn't download the program. I was ver
Experts, how do I add test points in the schematic? Are they the round test points? Can they be packaged? Can they be directly imported into the PCB? If I add test points in the PCB, it is easy to mis
