❓ Question
OLED
Asked a question 3 months ago

I am trying to make my OLED display work on my OTTO Ninja (the one without the arms/head). FYI the LED display works fine. But I cannot get the OLED to work after swapping it in favour of the LED display. In OttoBlocky I simply pick Example > OLED display and try to upload the code to the right COM port. But after a while Otto Blockly displays this error message: Error: Command failed: arduino-cli.exe upload --port COM4 --fqbn esp8266:esp8266:nodemcuv2 sketch/sketch.ino Traceback (most recent call last): File "C:\OttoBlockly\compilation\arduino\packages\esp8266\hardware\esp8266\2.7.4/tools/upload.py", line 65, in esptool.main(cmdline) File "C:/OttoBlockly/compilation/arduino/packages/esp8266/hardware/esp8266/2.7.4/tools/esptool\esptool.py", line 2890, in main esp.connect(args.before) File "C:/OttoBlockly/compilation/arduino/packages/esp8266/hardware/esp8266/2.7.4/tools/esptool\esptool.py", line 483, in connect raise FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error)) esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header Error during Upload: uploading error: uploading error: exit status 1 What am I missing/what is not working here..?
