Based on the basic polling, set Rx to interrupt reception. Hardware environment: tg stk, transient connection of PD0 and PD1, Tx and Rx of usart1, without using the internal loopback function. Corresponds to the 4th and 6th ports of the tg stk 20

1. Can this chip use the fatfs file system? A: The fatfs file system is only implemented in the FAT32/16 file format and can be applied to any media (such as norflash and nandflash, however, the file system format must be used before the

Two days ago, I wrote a . Because SPI is similar to I2C and there is idle time, the SPI module is implemented by referring to the previously written I2C module. The Code is as follows. This code has not been debugged. My current board does not use
