PICKIT-3 Programmer Tricks

When I first bought this old buddy, I thought it was dead, corrupted or something wrong there. But then, I figured it out after some late nights that it still work flawlessly with even latest MPLAB X IDE/IPE 6.20 on Ubuntu 24.04.1, even when USB Tools keep showing errors about some libusb_AccessLink_xyz not found. So lemme save you a day of googling ;)

1. Old firmware :

It does work flawlessly with Pickit-3 Programmer Standalone 3.10 Application but doesn't on MPLAB X IDE/IPE 6.20+.

This is because yours was flashed with old firmware/os/bootloader version from the seller, they tend to share/pre-flash it with this v3.10 program firmware so it can be recognized easily with it.

How to setup PlatformIO & CH32 on Ubuntu 24.04.1

Setup

Don't use sudo apt install platformio but if you did, try sudo apt remove platformio before proceeding further.
Install python-venv :
```
sudo apt-get install python3-venv
```
Install PlatformIO :

	#include <avr/io.h>
	#include <util/delay.h>

	#define HFUSE 0xDF // Default for ATmega48/88/168, for others see
	#define LFUSE 0x62 // http://www.engbedded.com/cgi-bin/fc.cgi

	/*
	#define DATA PORTD // PORTD = Arduino Digital pins 0-7
	#define DATAD DDRD // Data direction register for DATA port
	#define VCC 8 PB0

	{
	"workbench.startupEditor": "none",
	"workbench.activityBar.visible": false,
	// "workbench.editor.showIcons": false,
