Or even the alphanumeric LCDs as we’ll see in the upcoming tutorials. The parallel IO ports can still be used to display your data in a more convenient way such as 7-segments display as we’ve discussed earlier in this course. Using the parallel IO ports is kind of inefficient way to do so as you’ll be unnecessarily using a whole bunch of IOs & still getting binary output which may not make that much of sense in many situations. Despite having your variables stored in the RAM, you still have no way to display them other than using the parallel/serial ports. However, in the Embedded-C programming, you just can’t do that.

The process is as follows: A variable in the RAM of the PC is sent to the display device (screen) of the same computer. Quantity Component Name 1 PIC16F877A 1 Breadboard 1 Jumper Wires Pack 1 USB-TTL Converter 2 LEDs 2 330Ω Resistors 1 4MHz Crystal OSCillator 1 LM7805 Voltage Regulator 1 9v Battery or any Power Supply Source 1 PICkit3 (PIC Programmer)Īs you might have learned in the C-programming class/course, for inspecting (checking) the value of any variable in your program you’ll just pass it to the printf() function and it’ll get displayed on the console screen of your computer.

That I am going to explain in my next post " how to configure winpic800 with a JDM programmer". The winpic800 need to be configured with JDM Programmer according to PIC18F4550. Double Check the Circuits after you are done with construction. RS232-8 is connected to RS232-4 with a 1.5 k resistor. 9 on SV2 and pin no 12 on SV1 is connected to pin no 11 in SV2. Please note that pin no 11 on SV1is actually connected with pin no. On SV1 only pin no 1,11 and 12 are hard active lines. With a 40-pin base YOU will be able to easily chip off the microcontroller from the JDM Programmer board any time after you are done with programming. Use a 40 pin base for holding the microcontroller don’t solder the microcontroller into board. While buying these components take a printout of the schematic along with you. Follow basics of schematic, DOT shows connectivity of lines in schematics, Ignore the incomplete lines that I have left in the second schematic. Please don’t mind some left out lines in the schematic :), just ignore the incomplete lines and follow hard lines. In the second schematic all the components that we don’t required for our 40 pin microcontroller is roughly removed. SCHEMATIC -2 ( follow this one for your hardware) The 1st one is actual schematic which can be used for verities of JDM supported microcontrollers (you can modify it according to the type of microcontroller you want to use) and second one is the modified schematic (removed all non-required components for our microcontroller) which we are going to use for 1st time programming of our pic18f4550 USB interface board. FOLLOW THE SECOND SCHEMATIC FOR 40PIN Microcontroller board. I have posted both the actual Schematic and modified Schematic below. I have modified the actual schematic according to our need for this programming 40 pin microcontroller. I don’t remember where I found it, but I still have Schematic for making it. I found a nice tutorial about long time ago for making this JDM programmer. If you are thinking of a USB programmer then pickit2 or pickit3 will be a good option.

So I recommend use a Desktop Computer which comes with an inbuilt DB9 Serial port. Don’t even think about USB to DB9 converter, it just won’t work. Usually now a days laptop's does not comes with a DB9 serial port, so if you are thinking to use a USB to DB9 converter cable for doing this job then its a bad idea. I recommend do not use a laptop for JDM programmer.

This JDM programmer uses RS232 DB9 port to program the code into the microcontroller. As of now with this JDM programmer we are going to program PIC18F4550 USB Interface Board for FIRST TIME BURNING OF CODE INTO THE CHIP Later for a better programmer I recommended pickit3 from microchip which makes it easier to program with a USB port. So it’s a good option for beginners to stay with JDM programmer as cheap alternative in the early stages. It works with lot of other hardware too, which are similar to JDM programmer, like the but it costs around 60 € from their official website. Winpic800 is compatible with pic18f4550 and JDM serial programmer.

This jdm programmer responds, or lets us to burn the program into the microcontroller chip through small software known as winpic800.
