We use in our application 99 slaves connected to the I2C bus via the same adress 22. During sending data sometimes one slave holds the SCL line to LOW, which then blocks the whole system. Our idea is to have an interrupt routine, running as another parallel task, which detects SCL going LOW and if the line does not go HIGH again within a certain time (e.g. 500ms) the slave shall raise a flag to reset the I2C and give it free then it shall reconnect the I2C for further I2C data. Do you think you could program this? Please use attached program to modify with your deblocking subroutine.

@elect2eng

Hello, It looks like we may have to re-structure the slave code to avoid the problem. Please come for chat hey, is there any reason that you want all the client to be of the same address? We can connect one more io pin to monitor the SCL as mentioned and that pin can be external interrupt pin!!
