WebMay 6, 2024 · Here My I2C communication takes 44 mS. and the rest of the code takes 1mS. If I turn off all my delays I get. 5 , 8 , 8 , 575 , 0 , 0 , 0 , 2.81. My code still runs and cycles though the loop just fine. We can see my I2C communication time dropped from 44 milliseconds to 3 milliseconds. WebNov 30, 2024 · Point 5 and 6 state that you cannot use long communication routines (serial, I2C, SPI, anything) inside the ISR. These are common to all microcontrollers generally speaking, so my advice is don't use the interrupt, at least not in this case, since reacting to a user interaction is slow (even 50-100ms will not be noticeable).

WebAug 11, 2015 · The I2C bus is an open-drain bus which means that you only drive 0's on the bus while 1's are generated by the pull-ups (therefore it's so much slower than SPI). The way to bitbang that, if you can't tri-state your IOs is to set the PORT pin to '0' and use the TRIS register to drive the bus.
