我也正在尝试让 I2C 总线正常工作。 我正在使用较旧的DAVE™工具,它可以自动生成 I2C 低级代码。 您的项目是否生成 i2c_master.c 文件的工具?它已经具备您需要的许多功能。 附件是我DAVE™生成的 i2c_master.c 的示例 。 您能查看正确的 USIC 通道内的 PSR_IICMode 寄存器并查看交易后发生...
Repeated Start Condition A way to claim the bus During an I2C transfer there is often the need to first send a command and then read back an answer right away. This has to be done without the risk of another (multimaster) device interrupting this atomic operation. The I2C protocol defines...

We are using the PCAL9554B and would like a clarification of its behavior whent eh I2C Hold time for the Start condition is breached. Problem Summary: Due to bus delays caused by I2C isolators & buffers our SDA like sometimes goes low ~60ns before the SCL line itself goes low. Th...

The use of this so-called "repeated start" is common in I2C. A Stop condition ALWAYS denotes the END of a transmission. Even if it is issued in the middle of a transaction or in the middle of a byte. It is "good behavior" for a chip that, in this case, it disregards the ...
XferOptions variable is always set toI2C_NO_OPTION_FRAMEin theHAL_I2C_Transmit_IT. So, once the Xfer is completed, it firesI2C_MasterTransmit_TXE. As the following condition is always false (stm32f4xx_hal_i2c.c): if ((CurrentXferOptions != I2C_FIRST_AND_LAST_FRAME) && (CurrentXferOpt...
