Hi you guys, here i'm writing again some troubles.
I have a PIC18F458 and a PIC18F4580 microcontrollers but i being having some troubles to programming them... i build the SCHAER+ (https://pagesperso-orange.fr/softelec/Projects/PIC18/SCHAER+/Projects_PIC18_Schaer_us.htm) but i couldn't erase the 18F458 after programming it.
My main problem right now is that programmer use it a 7407 chip, and someone tell me that chip is discontinued (don't know if that is true, but has being very difficult for me to get it)...and also if you don't have the DLL file you could not program another PIC...so thats a real trouble for me because in that web page the owner has not upload the DLL for the PIC18F458.
...soooo.... my question is if someone know a easy-to-build PIC programmer, with new components (not discontinues), can program the 18F series and hopefully works with ICPROG
thank you a lot you guys and sorry for my bad english.
sucks for a people that can't build it (very thin lines that can't be done at home)... only because of that. i really don't know that programmer....nothing personal.
It is a kit, I don't publish the artwork. Many have successfully handwired just the programmer section and it works great.
It's also a lot more than just a programmer, it's a debugger too and a UART tool. Handy stuff and since it uses MPLAB it automatically gets new firmware when required.
I sell the bare PCB too including the SIP resistors for $18, unless your time is worth nothing that's got to be cheaper than a DIY PCB (layout, etching, drilling)
**broken link removed** My handwired prototype. Just the basics (No 2N7000 or BS250) and using a 18F4550 I had on hand at the time.
The programmer schematic is clearly divided from the tutor in the manual. Yes it's real USB and very fast. You can omit the 2N7000 & short out the BS250 D&S if you can't get them locally. They simply add VPP before VDD programming.
The only thing that is "chicken and egg" is you have to write the code on the 18F2525 with something. Anything will do. JDM or whatever. Once it is written, you are good to go
After getting source and drain backwards on the BS250P, I am into being clear. And it really is working well. From MPLAB, from the Pickit 2 gui, plus from SwordFish using your instructions.
