HI all,
I have been developing a small board and application for CY8C4245 using I2C bus.
unfortunately, due to the current supply chain problems, we had to select a 4745 for our design, so we can release the product much sooner.
I configured the I2C exactly the same way as the 4245 in PSoC creator, but I have problems with the communication with 4745.
I have looked at everything I could but can't figure out why it doesn't work the same way... 😞
Am I missing something?
Solved! Go to Solution.

Hi,
the 8051 timings are respecting the I2C specification, so I thought it would be ok. I didn't check the timing spec for SCB blocks though.
I have now replaced the I2C with EZI2C and the communication works just fine, so I don't think it's just the SCB version, but maybe the I2C slave driver specific to SCB V2?
