本帖最后由 nine_e 于 2024-4-26 16:41 编辑 nine_e 发表于 2024-4-25 15:11 大佬们，帮帮大佬们，走过路过看一看，读可以读了，就是写不进去（呜呜呜呜呜） EepromOperations_t eeprom_WritePage(uint8_t* TxData, uint16_t WriteAddr, uint16_t NumByteToWrite){ /* We gonna send commands in one packet of 3 bytes */ uint8_t header[3]; u8 i; header[0] = EEPROM_WRITE; // Send "Write to Memory" instruction header[1] = WriteAddr >> 8; // Send 16-bit address header[2] = WriteAddr; GPIO_SetBits(GPIOA , GPIO_Pin_10); sEE_WriteEnable(); // sEE_WriteStatusRegister(NULL); // sEE_WriteEnable(); // Select the EEPROM: Chip Select low EEPROM_CS_LOW(); for(i=0;i<3;i++){ SPI1_ReadWriteByte(header[ i ]); } for(i=0;i<NumByteToWrite;i++){ SPI1_ReadWriteByte(*(TxData+i)); } // Deselect the EEPROM: Chip Select high M95xx_DelayMs(1); EEPROM_CS_HIGH(); M95xx_DelayMs(10); // Wait the end of EEPROM writing EEPROM_WaitStandbyState(); // Disable the write access to the EEPROM sEE_WriteDisable(); M95xx_DelayMs(10); } 这是写入的新函数
