Hi,
A simple USB PC module for controlling a Oshonsoft HID USB based 18F2550 PIC.
All the programs and schematics are included in the attached zip file.
hi,
You will need the USB option from Oshonsoft, to enable the module to run.
I have attached a zip and an exe file.
The term2.exe file is the next stage of development, I am planning to bring out the final version during the next few days.
Problem for you Burt, had you done your degree 30 years ago, you wouldn't have been taught PIC's at that time. More like the Z80 mcu types.!
The latest scientific trials have clearly shown that its possible to continue studying and learning into very old age, so you have a long ways to go yet.
You are still a spring chicken, so keep at it.
If you have any suggestions about that USB module, changes or additions I would like to hear them.
Hi, I was trying to conect everything, I´m having trouble with my LCD because I have a differ model, y made the conecction and programing changes that apply to mine but still not working. This part of the LCD by now is the least I want to make work. By the other hand and the part I´m most interested is that I cant still conect to the usb and de pc the .exe file it tells me "HID connection failed" my next step is to change my 18f4550 for a 18f2550 maybe thats my problem but I want to ask the following: I remember that somewhere I read about adding de HID to de PC this step if its needed I had not do it, so I have to do it ? if so how?
thanks for your help
Do you have the Registered version of the Oshonsoft USB option.??
The 18F4550 will work OK as well as the 18F2550.
On your circuit do you have a 20MHz crystal and a 1meg ohm resistor in parallel, with the two 22pF capacitors to 0V, also is the Vusb capacitor 0.47uF.??
Do you have the hidterm.ocx, oca, dll in your Windows/Systems folder.?
hi Eric thanks for your help,
1. the register version of the oshonsoft USB option I checked and have the following information ( I have version 2.73 and I went to "help> View License Information>Info and got the 32 bit Math Support -Enable; Structure Lenguage Support - Enable; USB Support - Enable)
2. yes I have the 1M resistor with both 22pf capacitors and the 0.47uF capacitor
3. I missed de dll where can I get it?
