Well, Introduction part will be added later :)
PICkit v3.5 - programming kit
For programming of chip connect PICkit with PIC16F628A as it is in following table. Pay attention to resistor 22K between VDD and VPP.
| 1 VPP | 4 VPP (MCLR) |
| 2 VDD | 14 VDD |
| 3 VSS Ground | 5 VSS |
| 4 PGD (ICSPDAT) | 13 PGD (RB7) |
| 5 PGC (ICSPCLK) | 12 PGC (RB6) |
| 6 not con. | not connected |
I used for programming SW: MPLAB X IDE v5.50. In setup choose MPLAB IPE as this part of SW is intended as standalone simple application for programming. There can be some issues. For example I used previously some programming adapter connected to PICkit. Jumpers were set correctly, but PIC MCU had higher temp and I got error: Target Device ID (0x3fe0) is an Invalid Device ID. Please check your connections to the Target Device. After several hours of suffering and finding the cause of the problems, I gave up on the adapter and connected the MCU to the breadboard.
The right log from programming is following:
Verifying... The following memory areas(s) will be verified: program memory: start address = 0x0, end address = 0x7ff configuration memory EEData memory User Id Memory Verification successful. Loading code from D:\...\ps2m_aminet\ps2m\pic\ps2m_5button.hex... 2021-08-19 17:50:36 +0200 - Hex file loaded successfully. 2021-08-19 17:50:41 +0200 - Programming... Device Erased... Programming...

Blank Checking was clicked additionally just for sure :)
