How to get source code onto a PIC microcontroller

[@FriendlyWire]

IMPORTANT: There is a mistake at 6:21 for the PIC16F1455. The correct PGD/ICPSDAT connection is at pin 10, and the correct PGC/ICSPCLK connection is at pin 9. Pins 12 and 13 are the wrong connection, sorry for the confusion!

[@FriendlyWire]

@Planet of the Idiots Happy to, but an update on what?

[@FriendlyWire]

@Planet of the Idiots Yeah, but for what controller? And what kind of lines? If you have lots of complicated operations it will be very few lines, and if it's basic stuff it can be a lot of them. But the best part: you can actually download the XC8 compiler and the MPLAB IDE and give it a try yourself, for the controller and code you have in mind :)

@@billebrill8730 Yes, there is a lot of PIC controllers out there, and it can be very overwhelming to begin with.

Hi - Thanks for your video. With the power supply error at 10:00 minutes into your video, change the power setting to 4.75V and you can proceed past this self test ok. No external supply needed. 😁

[@FriendlyWire]

Oh yeah, good idea! It may work sometimes, but usually when the voltage breaks down it means that the PICkit3 cannot supply enough current (and there may be a reason for that, such as a large number of external components). Glad it worked in your case! :)

[@FriendlyWire]

Sorry for my late reply! I am not sure what went wrong... It could be a lot of things: wiring, unstable power supply, a bug in the code itself perhaps, a loose connection somewhere, or a USB port that cannot supply enough power. We would have to narrow it down some more. Did your setup work in the past, and not stopped working? Or is this the first time you are setting things up? (You can also get clones of the PICkit3 online, they are not so expensive as the newer PICkit4, and they work great.)

Hello. I am using Pickit3 for programing my PIC18F45K42. I have a problem with LED blinking. In code i set the while loop to bling the diode 5 times, but it keeps blinking forever. Does it something has to do with configuration bits of PIC18F45K42 or is something wrong with connections and my microchip maybe is resetting nonstop ?

Hi, kindly advice the followings. I fit capacitors on the rails RA7 and RA6 with a quartz oscillator, it lights up the LED on RB3. What if I change the nF value of capacitor? what if I put a polarity capacitor instead? Thx.

[@FriendlyWire]

My goodness, I just saw this comment from 2 months ago. Sorry to be so late to the party, and thank you @advanceinkscape8494 for your perfect answer. Also, besides what was already said, usually you need to check the datasheet of your crystal and it will tell you what its "load capacitance" is. Say it's 10pF. Then, if you ignore stray capacitance, you can usually take each capacitor to be twice that value, so: 20pF each, or, as was pointed out above, 22pF would also do the trick. Also, a lot of PICs allow you to use an internal oscillator, in which case you don't need an external crystal and capacitors at all.

Yes, if the code protection bit is turned off by whoever flashed the PIC, it's possible. Just connect it as shown in the video until 8:17, but then click on "Read" and the PICkit will attempt to read out the PIC's memory and retrieve the .hex-file, if possible. Hope it helps!

Hello. I have seen this video a lot of times and I have made the same "Blinking" program as you and it works OK... BUT when I place the PIC16F627A in my Breadboard and turn on 5 Volt it seems very unstable. The diode is blinking one seequence and the stops but if I touch the PIC chip it turns ON and sometimes the diode just goes ON and stops again and other times the seequence is running. It seems that the chop is sensitive for my fingers... The PIC chip is only connectet to pin 5 for GND pin 14 is +5V and pin 9 RB3. Should I connect all the unused pins to ground or what could I do to make the system more stable??

If you have a PCB, check if there is a "programming interface" connector or something like that. A lot of production PCBs are designed such that the PIC can be flashed after being soldered, for convenience. If such a pinheader exists, it should be OK to flash it. Hope it helps!

Sir , mpli ixe in advance settings which password use?? Microchip ic read and save which software best for pickit3.5?

[@FriendlyWire]

I think the default password is "microchip" in the advanced settings, it should say somewhere in the window. I think the MPLAB IPE works with the PICkit 3.5, have you tried it?

[@Electrolab28Ag]

Really clear and understandable, A couple question... 1. If you have more than one VDD and VSS, do you have to connect power and GND to all points? 2. If I just want to read the data from one Chip and send the Hex file to another Chip. How can I do that?

[@FriendlyWire]

Thank you for your kind words! 1. In our case here, all circuits run on one VDD (typically 3V-5V) and there is only one ground potential. All chips are connected to VDD and to ground. If you connect the PICkit3 to such a circuit, then you have to connect the VDD pin of the PICkit3 to the VDD of your circuit (and hence to the VDD of all chips), and to the ground level. In general, you always have to make sure that the PICkit3 is connected to the VDD and ground of the controller you want to program. If your circuit has multiple voltages (say, there is also a 9V rail, and so on) the you have to be careful not to destroy the PICkit3, as it can only tolerate up to 5V. 2. Yeah, you can do that, provided that the chip does not have code protection enabled. Follow the steps in the video, and at 7:30, when you connect the controller, you see the option "Read" (in the same row as the "Program" button). If you click that button, you will be able to read out the current .hex-file that the microcontroller uses. The IPE will then ask you where to store that .hex-file, and then you can use that .hex-file and send it to other controllers, too. Hope that helps, let me know if you have more questions, and thank you again for your interest! :)

@@FriendlyWire Thank you for your prompt response. I did as you suggested but when I press the Read tab in the IPE it just say read successful and does not ask me to save it anywhere.

one more question on some other Topic, how and from where to get and download different supporting library's for PIC microcontroller ? e.g LCD library or I2c , or RS485 I mean any library

[@FriendlyWire]

Libraries are not so common with PIC controllers; the reason is that each PIC controller is different. You can search for what you want to do, say, control an LCD. When you find a project online for a specific PIC you can usually use it easily yourself for the same PIC. For really advanced topics, such as SD card memory management or USB stuff you find some libraries, but for simpler stuff you probably have to code your own. I think of it as an advantage (long term) because it really teaches you how to code, but for beginners it can be frustrating. Do you have anything in mind, in particular? I would recommend to get started with a simple project, maybe one from this channel, and then take it from there :)

Hello. Thanks for posting this video. I stumbled across it and wondered if this device maybe the answer to my problem. I have a motherboard on which the bios has failed due to my own stupidity as to how I flashed the chip (Winbond W29C020-12 32 pin 2mbit) whilst the onboard button battery was dead. I then flashed it a 2nd time and wrote over the back up (duhhh). The consequence is that the board cannot see a floppy drive or even a non accelerated ISA VGA card. The motherboard company are no longer around, but I have the bios on a floppy disk in the form of a .bin file which suggests the file is hexadecimal in nature. Would the mplab software be able to view this type of file in order to 'flash' it directly to the chip? Thanks.

How to measure three phase voltage 415v micro controller r phase voltage loop y phase can't read 415v phase voltage 0 measure sir if any formula

[@FriendlyWire]

Hey Ganesh, thanks for the question! For measuring AC voltages I would definitely recommend to use some sort of galvanic isolation, like an optocoupler. AC line voltage with 50Hz is rather slow compared to the MHz resolution you can get with PIC microcontrollers, so it would be relatively simple to detect a zero crossing. But I am not sure if I understand the rest of your question, can you explain more? :)

Very good video sir, Is there any way to upload a hex file onto a PIC microcontroller without using a PICkit, instead using an Arduino?

Thank you for your kind words :) Yes, it is probably doable, since you just need the three wires MCLR (Master Clear), PGD (Program Data), and PGC (Program Clock). But I am not an expert on doing this. If you search on Google for "homemade PIC programmer" I am sure you will find many helpful resources!

[@yaseralali6309]

Did you solve the problem ?

[@MrWatlow]

I want to do the opposite, I want to pull the code from a PIC provided that it isn’t protected. How is that accomplished?

[@FriendlyWire]

Good question! It is impossible to obtain the C code from the PIC, all you can do is get the .hex-file. At 6:54, if you are connected to the PIC, you can click on "read" and that reads out the program memory, if it is not protected. The reason you cannot download the C code directly is this: it doesn't exist on the controller. C code only exists for us as a tool, but before it gets onto the controller it is compiled into the .hex-file. Hope this helps! :)

[@MrWatlow]

@@FriendlyWire that is fine. If I can get the hex code, I can then download it to other PICs to duplicate the same function, correct? Also, if the PIC in my equipment had the part number removed by the manufacturer, how do I figure out which one it is? I have the schematics of the board and all pin outs.

[@FriendlyWire]

@@MrWatlow Yes, the .hex-file is all you need. There are many PICs with the same packages, but their connections PGD/PGC/MCLR tend to be at the same place for all PICs in a given package. But you still have to know what PIC it is. You can try this: maybe you think it's a PIC16F627A. Configure your MPLAB IPE to PIC16F627A and try to connect the PICkit3 to that mystery PIC. If it works, it's a PIC16F627A, if it doesn't, you have to keep trying.

@@FriendlyWire i have just tested some PICs with this PICKIT3, and I must say it's a very hard time finding a working version of IDE/IPE to actually let you connect the device.

I am sorry this is so expensive... It seems a bit extreme, to be sure. If the developer has not activated "code protection" you can read out the .hex-file with the PICkit3. But I am sure they enabled the code protection using the configuration word of their PIC, which is what companies can do to protect their intellectual property. In this case it is not possible to get the .hex-file from the PIC.
