avrdude | avrdude with HID keyboard programmer driver | Keyboard library

I have created a GUI in python using Tkinter which connects to an Arduino nano. I can use my GUI to flash the firmware on the Arduino using AVRDUDE with no issue but this pops up a CMD box while programming. What I want is to redirect or pipe that to a text box to my GUI instead. If I use normal windows command like ping, dir etc, this works with no issue (example code and screenshot below) but when I try and flash the Arduino, it does flash but still in its own console and does not redirect. I'm guessing the AVRDUDE printf that's the issue but is there a way to redirect the output?

I have also tried adding "2> e:\\output.txt" to the end like in this link https://learn.sparkfun.com/tutorials/raspberry-pi-stand-alone-programmer/parsing-output-from-avrdude-w-python to save to a file then I can read in the file. If I do that in CMD, it works but not if I try from python, I get

Bad parameter >2

even if I try >> test.txt.

Hello friendly people of stack overflow!

I am currently working on a project using an Arduino Uno. Because i create all my files and sketches using a c++ program, i want to eliminate the Arduino IDE from my workflow. For that i can very easily use avrdude (which the IDE uses anyway) and some windows console commands. These are the commands that i am using:

"C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avrdude" "-CC:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -patmega328p -carduino -PCOM4 -b115200 -D -Uflash:w:C:\Users\Jzargo\AppData\Local\Temp\arduino_build_766345/EPaper_TestDither.ino.hex:i

"EPaper_TestDither.ino" is the arduino Sketch i want to compile and upload. When using the console and manually inserting the above commands, everything works as expected.

And here comes the part I am struggeling with:

Because i also dont want the user to manually open the console and type in some gibberish code, i want to integrate this command into my c++ program using the system(); function:

I have a string code.

Im using Windows 10 and try to setup tesnsorflow scripts to work with my new RTX 3070 GPU. Previously I had it working on GTX 980.

Hey I am working on a small project and I somehow managed to cause that setup is running more than once and on top of that new code won't upload to the board. I am not entirely sure what it is I've done wrong but I can't find answer so I am asking you guys.

I'm working on a custom bootloader for OTA updates for my ATmega328p. I'm taking help from the Optiboot bootloader's code from Arduino and for the USART part, I have written a custom header file for handling USART comm. part. Here's is the code (check code basically to test the logic)-

I am using atmel studio and usbasp.I am using this code:

Installed manjaro by recommendation. Im Very tempted to just go back to a deb based distro right now.

I've uploaded program to ATmega88p, then executed avrdude with -U lfuse:w:0x63:m -U hfuse:w:0xD9:m -U efuse:w:0xFF:m to set clock to 128kHz according to http://www.engbedded.com/fusecalc/ The proggram executed fine, but then I wanted to execute avrdude with -U lfuse:w:0x7F:m -U hfuse:w:0xD9:m -U efuse:w:0xFF:m to set the clock back to 8MHz, but I've received error rc=-1. When I used avrdude with -F to check the signature, I've received 0xdc57df, wchih looks random. Prevously I did same thing (with diffrent h and l fuses values) to ATmega8, and it worked just fine afterwards. I wanted to know if I should set extended fuse in the future or Is the high and low one enough in most cases?
