Hello
I'm designing an automatic signal switcher for the ICD3 (or clone), to isolate the I/O ports from the programming lines automatically. But i have a problem... that i haven't been able to solve for now.
I need to use my own VPP instead the VPP supplied by the ICD but only when the ICD is...
Hello.
I'm trying to create an automatic switcher for the programming signals to isolate the ports when the ICD3 is programming and reverting to normal ports after.
The problem i have is when i try to interface the VPP line, because the target device is not recognized and many times the ICD3...
I haven't rev C but i have rev B schematics-pcb. I made the clone (Eagle) and it works perfectly.
You can have firmwares and notes for configuring it here:
Here you can find an example to use the ICD2 clone debugger:
And finally... (i found it in the main thread but i don't remember who...
First, i don't know if someone has posted anything related...
Has anyone tried to power PICS clone (B) with a external power supply? I mean, don't powering it from USB port.
It shouldn't be a problem connecting it directly and don't use the USB power, but...
Re: can not program 18F4550 with te20 & winpic (for ICD2
hahaha it's an old post, anyway i'm pleasured with point and i never tried with pgm to ground. Or i can't remember it.
Tested firmwares
Because i'm bored and when i'm bored i do stupid things... i'm going to test in my PICS (b) ICD2 clone, the 3 firmwares that are supplied in this thread. No problem, it's not the first time i used it for experiments... and i still am alive :D
I will comment my results...
Hello, i wrote some posts about it. If you follow exactly it must work, at least works for me each time i tried (yes, i reprogrammed the icd2 clone from scracth several times to test if steps were correct)
Build and programming steps:
About "debug" mode errors:
And i found today this...
Please, english. 1. Forums are in english. 2. Not all people know spanish neither other idioms.
Well, let's go:
*The link to microchip forum where found the different problems behind that error code, is: **broken link removed**
*In the source file, you can find some notes about debugging. In...
In previous posts, somebody posted a link to microchip forums which has information about it (i'll post it later because i haven't the info here).
Anyway you have to set your code propertly in order to debug.
When arrive at home I'll post all i know and a working example with 16f877a (blinks a...
Which icd2 clone have you made? PICS, Potyo, ... ?
I only can talk about PICS's that is which i made. It doesn't work with 3.3v devices.
You need a level adaptor 5V-->3.3V for the PICS ICD2 (revB). Teskan and picnoobie posted some variant of
PICS to support 3.3v devices and a simple level...
I have tested my circuit in debug mode (tested with 16f877a target)
It works perfectly with MPLAB 7.6, debugging without problems.
I attach the source that i wrote (it is not nice, only for testing purporses). It has
notes about ICD2 debug mode and how to set it. Anyway, you can read the code :D
1. Program 16F877A with firmware in PICs zip. Default settings
Do the same for 18F4550, but use the firmware with MCLR dissabled.
Use the firmwares.zip file attached. I got them from this thread.
Have some snapshot of how settings are. If settings aren't the same, maybe
.hex is...
I can confirm you that my scheme works. It's exactly the same than original PICS one, but in eagle format (and some component moved due to i use wider tracks).
1. You don't need to change any option win winpic. Only load the hex file.
Try the .hex modified with MCLR EN disabled (search in...
