To do this easily keep a FRC male connector connected to the necessary pins of the PIC. Now whenever you want to program the PIC put off the application circuit power supply and then connect the ICSP wires coming from the programmer directly to the pins of the PIC which are specified. In mine they were connected to LED’s through resistors. To use ICSP, I did the following connections:ġ.Vdd to cathode of IN4148 diode and anode to Vcc of application circuitĢ.Vpp similar to Vdd but with 10K resistor in between anode of the diode and Vcc of the circuitĤ.PGD and PGC depends on the application circuit. Is there something wrong with the schematic or it’s just me with the wrong settings? But when I test both output VCC/MCLR the maximum voltage I can read is only 5v max. As the others saying, it should reach about 13v & 5v. I don’t know if there was wrong with the VCC or MCLR voltages.

I even try to set the serial port settings but it gives the same message again and again. I check the diagram many times, and it was the same as it should be. And I get this message:ĭo you want to use value from file (0FFFh) instead?Įither I choose yes or no, this message pops up when it starts verifying the PIC chip. But when I programmed the chip, the green led doesn’t light up. I used IC-Prog 1.06B when I read the 12C508 chip the yellow clock led also lights up. When I plug it in, the red led lights up.
Hi, I built this programmer on a breadboard according to the schematic diagram. Related Products: Memory | Memory Misc | EEPROM PIC-and-EEPROM-Programmer You may use a ZIF socket instead according to your needs. Don’t forget! Wrong placement may defect your IC, programmer or computer. LED Indications: Yellow:Clock, Red:Power, Green:Program You may use ICPROG and WinPIC to start programming your PICs or EEPROMs. If you don’t miss any short-circuits, you will see the red LED will bright up when you connect the programmer to the serial port. Another issue, don’t forget to solder the diode (D6) and the jumper under the sockets first. Before soldering the 40 pin socket, you must cut the plastic bridges between the sides. You can apply it to the board by using the ironing method.Īssembling the components is straightforward. SV2, SV3 : 20 Pin Machine Tooled IC Socket SV1 and SV4 : 40 Pin Machine Tooled IC Socket
On the other hand, if you want to use it with a laptop that do not provide RS232 connection, using the circuit with a USB to RS232 converter may not give a proper resultĪs you see the circuitry contains a few components listed below.Ĭ1, C2 : 100uF 16V Electrolytic Capacitor

The circuit is connected to the PC via serial port and no external power supply is needed.
So if you desire, you will not have to carry your MCU each time when you reprogram it. The programmer also provides ICSP feature that allows In-Circuit Serial Programming. In this project we are building a JDM programmer that can handle PIC12, PIC16 and PIC18 family microcontrollers and some popular 24C family EEPROMs.
