Ok, I have tested this on the logic analyzer and using an SSD1306. After some more optimization and a few fixes I managed to do I2C transfers (managed to turn on/off the display via I2C command line application). I also measured timings with delays on (if I configured for a 3uS GPIO overhead I got around 100kHZ as configured) and delays off (this went up to 480kHZ). An important optimization was to configure pin for output open-drain but input buffer connected. This allows to read the pin without having to reconfigure it. If anyone wants to give it a go and test with some device it would be great. Otherwise I think this is good for merging until it gets more in depth testing in real scenario. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
