In this code, I created two struct arrays to simplify dealing with either hardware or messaging. I have found that if the Pico is in an undetermined state, its best to follow this procedure. This will ensure your Pico is ready to receive an upload. Press and hold Boot/Sel (the only button on the Pico) then press/release Reset then release Boot/Sel. ![]() Rerun your program without having to upload or doing anything with the IDE.Connect one side to Ground and the other side to pin 30, Reset. This is easily fixed with a Reset button! Find you common variety bread board button and place it in your breadboard. This can be required a great deal when testing I2C and the unplug/plug-in is a bit of a pain. The single best way to ensure your Pico uploads properly (or more accurately) the Arduino IDE uploads to the Pico, properly is to press and hold the Boot/Sel button then unplug and plug-in the Pico. It also has a micro-USB connector instead of a USB C connector for the same reason. Arduino IDE is an open-source software program that allows users to write and upload code within a real-time work environment. While most RP2040 boards will have a Reset button, the Pico does not. Et voila, everything worked fine after we replaced the hardware.We inserted the original board again and our SW failed again.The board was send to a special department to check it and nobody could ever find something wrong with it.Where I share various observations as to how to use the Pico with the Arduino software framework and the legacy ( ~1.8.19) Arduino IDE. As that HW was hard to get at that time we had to halt the test of another machine to get the right hardware. Nobody agreed because all tests showed the HW was working fine but I managed to convince them to at least give it a try. It should be: \Arduino15\preferences.txt (Windows, Arduino IDE 1.6.6 and newer) \Arduino15\preferences.txt (Windows, Arduino IDE 1.6.0 - 1.6.5) \Arduino\preferences.txt (Windows, Arduino IDE 1.0.6 and older) \Documents\ArduinoData\preferences.txt (Windows app version) /Library/Arduino15/preferences.txt (Max OS X, Arduino IDE 1.6. At some point I said: "lets just change the hardware". Reminds me of the time when I still worked for Ericsson and everybody said a serious problem we had to be a SW error and we checked everything 3 times and couldn't find it. Trouble compiling in Arduino IDE for ESP32. Something odd is going on with that cable, I will dump it. Hello, Im trying to compile an example file and upload to ESP32, but i get this error: Arduino:1.8.19 (Windows 10), Tarjeta:'ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz. ![]() On the other hand, Mac and Linux automatically update the driver. This is because the driver for Windows is an information file that allows Windows to access the Arduino board as a serial port. They are treated as two separate applications so the installer makes a separate installation instead of the usual behavior of updating the existing installation. How do I update the Arduino IDE You need to update the Arduino IDE drivers in order to update the Arduino IDE if you’re a Windows user. I test it again with the NodeMCU, it fails. Hi richesonp installing Arduino IDE 2.x will not have any effect on the Arduino IDE 1.8.19 installation. Then tested that same cable to connect my camera to the laptop.and it works just fine. elf file (generated when you compile C/C code in the IDE, usually located in Temp folder). (This software works with AVR and ESP8266 architecture) This is a tool help to convert Arduino C/C code to Assembly code. I changed the cable for another and everything worked fine again. Convert your Arduino C/C code to Assembly code. So the cable that I have been carrying around with my laptop for some time, to connect drives and camera's (and NodeMCUs and arduinos) apparently decided to fail at the same moment I switched to win11. Well, I found my issue.after I did everything logical I started to look at illogical things.
