"You all are too polite. Somehow I overlooked the source code for the bootloader on the google code site. I have it now.
Thanks,
Mike"

Need Bootloader source code to change config bits

Dan (and whoever else can help!), I have developed a product using the CUI32 as the development platform. It has been great, very useful. However, I need to modify the config bits in order to use…Continue

Porting from the PIC32 Starter Kit to the CUI32?

Hi all,I've written a system in C on the PIC32 II USB Starter Kit. It runs fine on the Starter Kit. Now it is time to move it to the PIC32. I figure I'm in for some fiddling to get the USB stack…Continue

How to pass a digital output as a function argument?
2 Replies
In C I'm trying to figure out a good way to pass a hardware variable, in this case a digital output to a function. Compiler won't let me - which I think I understand because the digital output is…Continue

Need Bootloader source code to change config bits
Dan (and whoever else can help!), I have developed a product using the CUI32 as the development platform. It has been great, very useful. However, I need to modify the config bits in order to use the Watchdog Timer. This has to be done to the bootloader source code, since the config bits reside in the boot flash area and must be programmed at the same time the bootloader code is programmed. I see the bootloader hex file in the download section. But I need the source code so I can change the…See More

"I don't know what was causing the problem. I started a new project placed copies of all the files in that project and setup all the build option and now it runs. I have inspected the Project Build Options in both projects in great detail and do…"

"Hi Mike,
I don't have a starter kit, so haven't tried this - but the "Switch" example Markus Gritsch made works fine for me on both MPLAB 8.x and the new MPLAB X IDEs... it's about as simple as what you're trying to…"

"Alright Bruce, who did you bride to get that great call??
I'm reading your site and trying to catch up on what you have been doing. The blip video won't play and the LVBTracker link is broken (both on the qrpTracker page). Do you happen…"

Hi all,I've written a system in C on the PIC32 II USB Starter Kit. It runs fine on the Starter Kit. Now it is time to move it to the PIC32. I figure I'm in for some fiddling to get the USB stack to run on the CUI32, but I'm not trying to make that work just now.I'm just trying to turn on the LED at the beginning of the code. ie:void main(void){ LATE &= 0xFFF8; TRISE &= 0xFFF8; LATEbits.LATE0=0; while(1); and hereafter follows all the code of the system, which I don't…See More

"FWIW I thought of a solution: I use a structure. Such as:
#include
#include
struct LED {
unsigned int ledport;
unsigned char ledbit;
};
turnonLED(light);
main(){

"Nice writeup. Thank you. "
Mike Watts replied to Mike Watts's discussion Why does one project produce code that runs while another does not?
"Ok, here's the write up on Using a MicroController to Perform Zero-Crossing Switching of Inductive AC Loads. If you don't want to bother to download it (it's a little bit large - I don't have winzip on this machine), it is also…"

"Sounds interresting. Maybe you want to post some photos, schematics, source code..."
Mike Watts replied to Mike Watts's discussion Why does one project produce code that runs while another does not?
"Thanks Markus. It is painful but I'm catching on. I've created my first real embedded C program. It controls relays that switch AC power to inductive loads on the zero crossing of the AC current going into the load. This protects relay…"

"The procdefs.ld file is from the Microchip bootloader example folder. You can find it there. And yes, a linker script is always used."
Mike Watts replied to Mike Watts's discussion Why does one project produce code that runs while another does not?
"No, I found the procdefs.ld file over on the CPUStick site. That discussion makes it clear the file is for that processor with the bootloader - although there is nothing in the file itself that says it is correct for the PIC32MX440F512. Do we know…"
Markus Gritsch replied to Mike Watts's discussion Why does one project produce code that runs while another does not?
"So you didn't search the forum for postings about the procdefs.ld file, well http://overtone-labs.ning.com/forum/topics/loading-and-running-newbie?commentId=3789944%3AComment%3A1678"
Mike Watts replied to Mike Watts's discussion Why does one project produce code that runs while another does not?
"Markus,
Thanks for the help. Yes that file, when placed in the same directory as the source code file, makes it all work. However, it makes the simulator not work. So I have to remove it to simulate and then put it back to compile the code for the…"
