I meant there wouldn't be anyone physically at the device. The device has internet connectivity so the HEX files can be transferred that way.
This would be a good kickstarter project. Any takers?

A PicKit2 wouldn't work. If another IC had SPI, RS-232 or some other communication protocol that would work, could that IC load the HEX file onto the PIC without human intervention?
I searched the forums and found a little bit of information but nothing that fits exactly what I need. Is there a way to load a hex file into an 18F without the use of a computer using SPI or RS-232?...
Old thread but very relevant to my issue.
Can I use HPWM10:
1. On an 18F87J50?
2. And have it glitch free?
3. To make a pulse train that's 140mS long and have varying duty cycles within the...
Referencing page 12 of the 18F87J50 data sheet, the diagram has arrows pointing from EUSART1 to Timer3 and EUSART2 to Timer4. Is that true? If not, which timers are they associated with?
For now,...
I assume the registers are set correctly since the MSSP modules work correctly with GOSUB's. I can't figure this problem out. It's a stumper.
I'm able to use the following interrupts from DT-INTS:
1. RX1_INT
2. RX2_INT
3. TX1_INT
4. TX2_INT
5. TMR1_INT
6. TMR0_INT
When I try to use SSP1_INT, the program hangs waiting for the...
Overruns aren't really a problem, except when that condition locks up the device. More importantly, you pointed out something I never caught onto. So there is a HSER@2_CLOERR 1 define.
I use...
That I didn't have in my program. Does it matter where the define goes? If I'm understanding the manual correctly, I shouldn't have to use this any longer? Also, didn't see it mentioned in the manual...
Yup, I did that. Like I said, I'm pretty sure the remote processor is the issue, just trying to identify why it's happening and how to limit the failures.
I receive with this:
IF RCSTA1.1 = 1...
I'm using an 18F87J50 to communicate with another processor at 115K. Most of the time the communication works fine but sometimes it gets stuck and when it gets stuck it's stuck permanently. I'm...
I'm a novice when it comes to the timers and interrupts. Seems like a good idea that's worth trying.
Idles low.
1ms on/1ms off

It's a 1 but it can vary. Before the packet is...
Richard has confirmed it's not RS-232.
I can identify everything.
I don't really need to convert the data into a "readable" format, all I need to do is accurately measure the on/off period in...
It is one wire communication. The voltage level is 18VDC. What you see in that picture the output from a RS-232 IC. I can identify the start/stop and know what each piece of data is. The problem is,...
This may be a case of a dog chasing his own tail but I'm trying to figure out if what I'm looking at is an RS-232 signal. I've tried various baud rates and it seems to be something around 9600 as...
I'm using the same footprint as a FM25V10 and the SST25VF032B appears to have almost the exact same instructions as the FM25V10. The problem is, no matter what commands I try, reading or writing...
I've found some threads that confirm the problem I'm having but none that provide a resolution.
Why doesn't this work:
HSERIN 1, [STR DAT\800\"@"]
But this does?
HSERIN 1, [STR...
Thanks, I think this is what I was looking for. Seems complicated.
I'm using an 18F87J50. What exactly do you mean when you say: Also, how do you see your PBP code in MPLABX?
I have an ICD3 that's been collecting dust. Every time I attempt to use it, I try for a little while, get sidetracked with something else and don't go back to it for some time. Then the cycle...
I know. That's what I've been doing but now it's becoming a problem because there are so many HSEROUT statements. A 2kB image takes up 17kB of code space. Is there a better way to send an image that...
What happens when you try to compile this code?
HSEROUT...
I have one.
I can't code wrap when the characters extend past column 255 even though we're given 1024.
If I have a line of code that's 150 characters long, is there a way to continue that code onto the next line so all of the code can be viewed on my screen without scrolling to the right?
Will do. One additional question. Why don't you have this line of code:
"HTTP/1.0 200 OK",13,"Content-Length: 800 ",13,13
written like this:
"<HTTP/1.0 200 OK",13,"Content-Length: 800>",13,13
