Webb9 aug. 2024 · The I²C bus is an 8-bit serial bus. The address is typically 7 bits long, followed by a bit to designate a read or write. For example, reading from the address 0x40 (0b01000000) would produce a 0x81 (0b10000001) on the bus, as shown in Figure 2 below. The eighth bit is a 1 for reading and a 0 for writing.

Instead, consider an I2C isolation device, and use TVS diodes on the lines for a more robust solution. (Experience: set-top boxes with HDMI as well as on-board I2C.) WebbThe I2C code below works most of the time but occasionally on power-up there is a bus collision (BCLIF) and the I2C module is unable to recover after the BCLIF. The I2C lines are pulled up by 3.3K ohms. Using REALICE and breakpoints I can see that i2c_write () resets BCLIF and returns FALSE when BCLIF is set. cpdl walford davies
