如何使用 HAL_I2C_Mem_Read 和 HAL_I2C_Mem_Write 函数读写 i2c eeprom。如何将 uint16_t 转换为 uint8_t 并将 uint32_t 转换为 uint8_t ...
应用程序是参数校准。 我想在 EEPROM 中存储更多数据,并且可以在连续写入模式下使用代码,然后在读取模式下使用,而不是一次写入和读取模式。 我相应地更改了代码、但唯一的问题是代码从 i2c 中发出时中断代码 按摩状态再次初始化并停留在该循环中。 向上0True向下 ...

Example Micro:bit functions to read and write to a Microchip I2C EEPROM A very simple example function for writing and reading data to an I2C EEPROM chip. The one I used was a Microchip 24LC128 - others in the same range should work too. IthinkI2C EEPROMS of other makes may work, but...
pointer every time by using two messages, first write to set the 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?
