Problem with USB and RFID training solution

[kmanng21]

Hello, sorry for my bad english.
I have USB training solution using PIC 18F4455 and RFID solution using PIC 16F1937. I download program by Flowcode V5 from example directories of CD included in kit.
-My USB training solution problem is when i download example 1 (about mouse) it work correct, after that i download example 2 (keyboard) it also work but after that i cannot download any more, flowcode and ppp says that they didn't recognise 18f4455.
-My RFID training solution problem is when i download example 9 (the last example of CD), it didn't work, the LCD show "-----?????-----???" and when i put Icode or Milfare card into rfid board, the green led on 1second and off, it's blinking between red and green led. I see that program is for 16F1937. I figure that no example of the CD-ROM work.
How can I fix that.thanks.

Hello,

There is occasionally a mode which the 18F4455 devices go into and they are then none-reprogrammable. I will investigate this for you and see if we can find a fix. There may be a way to bring the device back by manually performing an erase using PPP. Otherwise a known way to bring back the device is to perform an erase using a PICkit. I’ll look into this and let you know. Out of interest what version EB006 are you using?

Please can you try and use the attached replacement program for the RFID. It should now allow the LCD to work correctly. The actual RFID connection to the Card can be tuned by using a small screwdriver to adjust the tuning capacitor on the E-block until you get a better response.

hello,
I can not check what version of EB006 because I had sent all trainning solutions to my customer. But this USB and RFID trainning solution are shipped to my company about 3 week ago.
