You may have intended to say SPI. I²C does support "clock stretching" to delay until ready, but that's only in one particular case; otherwise the I²C clock advances all the time at whatever your baud rate is, not only when a pin is explicitly toggled.
- Skunkleton 2y agoThat depends on if you are the controller or the target, no? My usual use case for i2c is for talking to some peripheral from a microcontroller, where I am acting as the clock source. Clock stretching applies to the target side, at least when you are talking about SCL.
- kragen 2y agoHmm, on thinking about it further, I guess I was pretty comprehensively wrong. Thank you.
