Webb25 apr. 2024 · 对不起！我还是坚持把i2c肝完了，废话i2c其实肝的我挺难受的，通讯协议这种规范往往可以抠出很多的细节，看了波叔的文章《万变不离其宗之i2c总线要点总结》，很详细。我打赌我还不会i2c，因为涉及到很多技术细节，在实际项目中往往是会被忽略的问题，于是结合自己以前的项目经验，简单再 ... WebbThis particular IMU uses clock stretching which doesn't seem to work with the HAL_I2C library that was auto-generated from STM32CubeMX. See image below: I attached a second I2C device to the bus and was able to communicate with the library so I'm pretty sure it is only the clock stretching that is causing an issue.
