I have been using arduino UNO loaded with GRBL 0.9i firmware and UGS. Everything was working fine. Recently I faced a problem in a laptop running windows 8.1 The serial port connection used to get disconnected frequently. I was facing this problem the whole day. ...
Re: ESP32-C3 supermini serial port problem Postbylbernstone»Tue Apr 16, 2024 4:48 am What version of arduino-esp32 are you running (you can see this in the board manager)? There were some issues with earlier versions of esptool on the C3, but if you are running 2.0.15, that ...
Unfortunately the 24MHz isn't that faster in computation as expected. Therefor I would like to move to an ARM as well. I have an Arduino Due lying around doing noting so I could use that board to do the job. Another why to get there is to use an STM32F103 development board ( extrem...
✅ usb com port problem:I am trying to use my win10 laptop to connect via USB to an Arduino UNO clone which has a CH340 chip. When I try to load the CH340 driver the installer...
Posted this question on Arduino forum also, but nobody has been able to help me find a solution to the problem. Without a functioning serial monitor, it's nearly impossible to see if my board and code perform the way they're supposed to. Is there anything else I need to do in Arduino...
