PIC24FJ256GA106 - 64-Pin, 16-Bit, General Purpose Flash Microcontroller with Peripheral Pin Select.
The program is developed in C language in the MPLAB X IDE development environment. All the settings of the program correspond to the above diagram. The program has been thoroughly tested and verified with the help of various GPIB testers and devices. You can extend any, made a separate module without making any changes to the main PCB.
