Use avrdude. The command format is simple, assuming you have installed it from the Linux repositories: avrdude -carduino -patmega328p -P/dev/ttyUSB0 -b115200 -Uflash:w:/path/to/project.bin.hex:i Depending on what bootloader is installed in your nano you may need to change the baud rate (-b115200) to 57600. Also, of course, the USB device should be set to ...

The problem is in kernel ch341 driver. Using 5.3.3 on Archlinux and 5.6 rc1. https://github.com/torvalds/linux/blob/e33eab9ded328ccc14308afa51b5be7cbe78d30b/drivers/usb/serial/ch341.c This driver version compiled using this Makefile obj-m += ch341-m.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/...

EEPROM on the ESP32 doesn't work like you would expect. It uses the SDK's "Non-Volatile Ram" storage system to store the data within the nvs partition. This works through a system of "Key / Value" pairs, and the data is stored as a "BLOB" (Binary Large OBject) for the key eeprom in the namespace eeprom. Quite what the internal layout of the data within ...

Uno's Mega's and so on have a separate MCU (u3) that contains the boot loader and is responsible for the USB connection and for driving the virtual serial port. Micros ( and also Leonardos and Esploras ) have built in USB support in the main MCU (u4). So if your program does something that breaks the USB part of the MCU the communication breaks also. This ...

Okay I found a way to do this. Open Terminal and type: ls -l /dev/ttyACM* you will get something like: crw-rw---- 1 root dialout 188, 0 5 apr 23.01 ttyACM0 The "0" at the end of ACM might be a different number, or multiple entries might be returned. The data we need is dialout (is the group owner of the file). Now we just need to add our user to the ...

Here is a trick I use on some boards but first be the baud rate is the same in the terminal as in the sketch (Serial.begin(115200). If so then remove everything then put a jumper between ground and reset. Then put a jumper between TX and RX (pin o and pin 1 on uno). launch the IDE and what you type in the console should be echoed back to you. If this works ...

This is because you are running the Windows App Store version of the IDE. Windows doesn't like you messing with the insides of App Store programs (I think it scares it...). Install the real version of the IDE from the Arduino.cc website and it will work.

First of all do yourself a favour and listen to your IDE This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. and in an if else there is no in between so either let it run as a state machine especially inyour case A != B != C != other: void subfunction(){ if(A){ // code to ...

Download the Arduino software (IDE, or Integrated Development Environment). In our case, we only need to download and run Windows Installer and follow the pop up instructions. When asked if you want to install the Arduino driver, just press Yes. Connect your Arduino Nano board to your computer. In this step, Windows should automatically find the proper ...
