What is JDM programmer?

This is a serial programmer works on the RS232 ( PC serial port ), known as JDM Programmer, thanks to the site http://pic16f84.hit.bg/ which contains the schematic and the programmer software. The programmer is powered from the Serial port itself, so there’s no need to any external power supply.

How do you program a microchip studio?

Open Atmel Studio and navigate to Tools->Device Programming dialog box. Select the programming tool, device and the programming interface. Read the Device ID to verify the connections between the tool and the device. Select the binary to be programmed (hex/elf/bin format) and the options (Erase/Verify).

Which programming language is more efficient C or assembly?

Actually, the short answer is: Assembler is always faster or equal to the speed of C. The reason is that you can have assembly without C, but you can’t have C without assembly (in the binary form, which we in the old days called “machine code”).

Can you reprogram microcontroller?

So yes, it is theoretically possible to reprogram the chip, but you’ll have to start from scratch. And again, the answer may be different for different chips.

What are the parts of a PIC18F2550 programmer?

24xxxx, 25xxx, 93xx6, DS24xx, 11xxx. It is the major part of the programmer. It consist of PIC18F2550 microcontroller as the brain of programmer. The USB-B connector is attached which communicates through PC. It consist of two indicator LED’s, one for the indicating in programmer connection other shows the programming status.

How do I connect my PIC18F2550 to my computer?

Then connect the PIC18F2550 to your functioning programmer using a breadboard and making the appropiate connections, like the image above shows. If it isn’t detecting the PIC, showing ‘PIC Device Found’, then try clicking ‘Tools > Check communication’ a couple times.

How does ADC work in PIC18F2550?

In PIC18F2550 the ADC is smart because of V REF pins. There are two Vref pin pins, one of them is used to describe the maximum voltage of input analog signal and the second one will be used for input of minimum voltage of analog input signal. By this way, the ADC only gives the output of values within the range given by V REF.

What are the SPI pins on PIC18F2550 used for?

It is known as a three-wire communication system which uses two data wires, one clock pulse wire and a third wire know as slave select, which is used in the case of multiple peripherals. SPI pins on PIC18F2550 are: It is a two-wire serial communication but it is one-way.
