While we are talking about Microchip, has anyone tried using the PIC32 as a USB bus powered device in your own circuits and did you have any issues as result ? It's on my todo list in the upcoming future, so I am trying to find any possible issues upfront. I've done some searching online but I keep hitting stuff for the PIC18 or even the PIC24 instead. I have not found anything explicit ...

Hello, I currently have an ICD2 from Microchip. I use it to develop PIC16 code using the MPLAB debugger and assembler. I need to move to the PIC18 parts and C language, but I am struggling figure out the development tools to get. Do you have any experience with the CCS compiler running with MPLAB and ICD2? ($175 solution) Thanks, Talal

Happy Halloween! Last year I built a collection of plywood pumpkins to stick in the yard on Halloween night. I installed superbright LED's in the eyes, nose, mouth, etc and was pretty pleased with the results. This year I want to animate the LED's. I bought a DLP-245PL which uses a PIC18LF8720 to drive it's digital I/O. I need a simple transistor circuit to drive each LED. There's a...

Hi, I'm seeing something unexpected in the running time of a Timer2 based delay loop. With the combined prescale, period, and postscale, should be setting TMR2IF at 500Hz? I expect the polling loop below to fall out after approx 2ms. But it's taking closer to 3.8ms* and I can't think of an explanation. Part is PIC18F6680, Fosc = 40 MHz. ; THIS DOESN'T WORK... ; Timer2 input = Fosc/4 ...

I am using a PIC18F4320 and have been trying to solve a very strange problem.. I have configured an interrupt using Timer1 which fires every 1ms. In that interrupt an ascii character gets sent, and is incremented, every time. Also, every 79 interrupts another section of the code gets executed, which just sends a '%' and resets the ascii code to '1'. Nothing else is going on AT ALL in the...

I'm a beginner using assembler on PIC18 and I try to understand the Branch (BRA) instruction. The Manual says that the parameter used with BRA is ADDED to the Program Counter (PC), but trying this with simple code makes me thing that the parameter overwrites PC instead. PC = 0xBE BRA 4h This should add 4 + 2 to PC but the PC actually jumps to 0x4! Am i interpreting the manual wrong?...

Hello all. I'm a newbie in the realm of micro programming. I'm using MPLAB C18 with the PIC18F452 and PICDEMO 2 Plus board. I can't, for the life of me, figure out how to do an interrupt routine! I've used the buzzer interrupt sample that came with the ICD2 software, but have been unable to modify it to suit my needs. What I want to do is wait for a button to be pressed to start my rout...

Does anyone out there know about a decent c compiler which targets the pic18 family? So far, I played with the Sourceboost C compiler and the Microchip C18 compiler, I'm happy with none of these, am willing to spend some money on something really good, but won't waste my time on buying and trying... -- Grinnikend door het leven...

I would like to build my own programmer for Microchip PICs. There are many schematics on the Internet available but I can't seem to find exactly what I want. What I would like is something that provides all (or most) of the following functions: * Can program PIC18 family of devices (or all of the major PIC families if possible) * In-circuit programming (not debugging): the electronics us...

I want to build my own hardware programmer to program the Microchip PIC18 series of devices. I want to use the parallel port or possibly the USB port. I don't want to use the serial port because they are now obsolete and no longer ship on newer computers. USB-to-Serial adapters cannot be used because programmers like IC-Prog and WinPic cannot work with these "virtual" serial ports - they need...

Hi, I have written a VHDL model of a pic18 micro, and I have written self test code which has run correctly in an FPGA implementation. I am looking for additional test code to run on the model to verify that it is operating correctly. Thanks, Scott L Baker

a) CONFIG/CBLOCK directive: I don't know what these directives do b) retfie dt; this is a Pic18 instruction. But, mplab uses only "retfie". Is it equivalent to "retfie 0"? If I comment these directive, then my files are compiled. But, the hex files are not same. Also, mplab generated hex files are not in previous (pic16fx) format. The header is in previous format. But, the body is bro...

Ok, I THOUGH I was following the C18 compiler User guide to a T, but I am having trouble getting the interrupts to work right. I am working with a PICDEM HPC, which has a 18F8722 as the main chip, I am just trying something simple to get an understanding of their interrupt system. The HPC demo board has 8 LEDs on PortD, the code powers every other LED 1010 1010. When I don't include t...

Hi. Can anyone advise please? I'm migrating code from a base device to a PIC18Fxxx. No real problems except the original code uses Pseudo-Instructions and I can't find equivalent(s) for the higher-end devices. Do they exist for the 18F parts or do I have to take say, CLRC and use BCF STATUS,C instead? Cheers, Simon

In March, I'll be teaching a class called Embedded Systems. The text (which I don't have yet) will use the PIC18???? chip and a free windows IDE that uses the C language. I'd like my students to be required to subscribe to and participate in related groups. Besided here, what other groups would be appropriate?
