@per1234 - you might want to see this and the following posts: https://github.com/arduino/ArduinoCore-renesas/issues/62#issuecomment-1653725275

@per1234 - thanks for the explanation - haven't run into an upload issue since installing the update but only been playing I2C libraries

@technoblogy try this for your pulse function: ``` void pulse () { for (int i=0; i

>Thanks, but my point is that calling pinMode() again shouldn't be necessary. I agree thats why I added it to make it painfully clear.

@greiman Did you see my comment to wire.setClock PR: https://github.com/arduino/ArduinoCore-renesas/pull/46#issuecomment-1636091204 and link to Forum post on that topic.

@greiman Sorry I didn't get back sooner been a crazy morning. I was trying to duplicate your results with a mix of 5v and 3.3v devices on the same bus....

@greiman = been testing a bit more today with a I2C test board that we used with the Teensy, same as previously but with more added: ``` #define _MPU9250_port Wire1...

Did some more testing with the BNO055 and TMP102 devices on Wire/Wire1. Confirmed they fail on both ports. Tested on a M0 board that I have and no issue. Did...

@paulvha - Actually I think I got it resolved. Out of curiosity I looked at another library for the BNO55 for the arduino: https://github.com/arduino-libraries/BNO055, and saw this//Pin assignments as tested...

[QUOTE] The BNO080 also suffers with clock stretch.. e.g. https://github.com/adafruit/Adafruit_CircuitPython_BNO08x/issues/7 [/QUOTE] Agree but I am using the Sparkfun library for the BNO080 and do not seem to have any issues...
