14. STM32F103C8T6 software SPI read and write W25Q64

Packing 4 communication pins, it is convenient to transplant to other microcontrollers to add delays. The SPI here is fast, and there is no need to add delays after operating the pins. void MySPI_W_SS(uint8_t bitValue) { GPIO_WriteBit(GPIOA, GPIO_Pin_4, (BitAction)bitValue); } void MySPI_W_SCK(uint8_t bitValue) { GPIO_WriteBit(GPIOA, GPIO_Pin_5, (BitAction)bitValue); } void MySPI_W_MOSI(uint8_t bitValue) { GPIO_WriteBit(GPIOA, GPIO_Pin_7, (BitAction)bitValue); […]
