I have been using the GreenPAK DIP development platform with SLG46537V-DIP and SLG46867M-DIP, accessing the IC with I2C (reading and writing) from an 8 bit uc without issue.
Then with exactly the same setup, I changed to use a SLG46826V-DIP. After turning on emulation mode, any attempt to use the I2C bus results in the error below
"Functional socket test failed. Socket issues detected."
the next time emulation mode is attempted. I have tried a number of different SLG46826V-DIP breakouts so far and the result is always as above and the DIP breakout is then permanently unresponsive. Replace the unresponsive SLG46826V-DIP with a SLG46537V-DIP and I can access the IC with I2C (reading and writing) without issue.
What I am doing wrong?
