1. Test conditions Hardware: STM32L432KC Main frequency: 80MHz Compiler: IAR 8.20.1 Compiler options: High Speed no size constraints CRC generator polynomial: 0x782f 2. Test Method The softwar...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[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]
Function List and Notes (lower-level driver part) 1. IO port initialization: control IO and communication IO. Control includes power control, reset and low power mode. Communication is the serial po...[Details]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
