Theeeprom_i2c_write()function writes a single byte of data to a specified address in the EEPROM. The function takes three arguments:addressis the I2C address of the EEPROM chip,from_addris the memory address in the EEPROM to write to, anddatais the byte of data to write. The function ...

我参考文档通过 i2c 写入 SRAM 和 EEPROM、 在写入 SRAM 中、看起来不错。 当我写入 EEPROM 时、它具有奇怪的状态。 我执行第3步和第5步以进行如下检查: 3.向 R137.0写入1。 这会将整个 SRAM 内容编程到 EEPROM 中。 完成后、将显示中的内容 R136将递增1。 R136包含 EEPROM...

pointer, then read. The per-adapter lock makes sure those two messages will not get interrupted. So, it looks to me that it would be OK if a serial read access gets inbetween a eeprom read access. Am I wrong? Description:
