hi all, finally i could go on with the build. after all the testing looks promising and i managed to upload the seq app i now have some strange behaviour when starting up. did a short video to demonstrate whats going on. https://www.dropbox.com/s/me76qsg77vcayf4/VIDEO0148.mp4?dl=0 the app seems to work but there is something wrong with the oled-displays in conjunction with the buttons. i have tested the ja-board and the le-mec boards. all buttons, encoders and leds work properly.
