WeMos D1 R1 not setting programmer
May 3rd, 2019 at 3:54am
 
When I create a sketch using the Arduino IDE and install the 'WeMos D1 R1' wifi board it sets the Programmer to 'AVR ISP' but the Visual Micro Programmer is blank and can not be selected.
When I try and compile it fails with the error:
"Error creating .hex"
This same sketch uploads and runs fine with the Arduino IDE.

Any idea on how to fix this? Undecided

Don't be confused by the arduino ide. It shows a programmer but does not use it unless you click "Upload using programmer"

You have an unrelated build error. Please follow the instructions at the top of this forum to show us your error detail and config.

+ You also have not said if a debug or release build. Testing should be in Release.

Hi... I've found a smarter way to do this. RTS signal correctly pulls down D3 so it is only sufficient to connect D3 and D8 together, they both get pulled down and everything works. Maybe a second pull-down transistor can be inserted in next wemos design if my analisys is correct.
