    Re: PIC16F1454 Connecting To USB Doesn't Work

    The 18F13K50 won't compile with the DT interrupt file ReEnterPBP-18.bas. This variable HP_Vars is in the DT ReEnter interrupt file. If you want to use this interrupt, you need to go with the...

    Re: PIC16F1454 Connecting To USB Doesn't Work

    I bought a few from Mouser. I'm hoping I can make the USB part work without any issues. I'll open a new thread if I have problems.

    Re: PIC16F1454 Connecting To USB Doesn't Work

    Yes, I agree with you. I had a hard time programming it just to flash an LED. Thank you for the explanation.

    Those chips are the cheapest 18F with USB according to the Microchip Advanced Selector Chip tool. I'll order some and give it a try.

    The good news is that the 18F25K50 isn't that expensive. I'll order some and I'll give it a try.

    Re: PIC16F1454 Connecting To USB Doesn't Work

    Bad news, I got this response from Melabs.



    We tried many years ago, but failed to make the USB commands work in a useful way. In any case there is no further development planned for PBP.

    It doesn't make any sense to me either.

    Re: PIC16F1454 Connecting To USB Doesn't Work

    Hmm, I made it work for a flashing LED. This is weird, you need to power the 16F1454 chip with 5V. It won't get programmed if I power it with 3V. I have never seen this for a regular 16F chip.

    Re: PIC16F1454 Connecting To USB Doesn't Work

    Hmm, I'm trying to make this chip work with just an LED and the chip is not cooperating. I'm getting a "Does not match target device" error. When I try to get the target information, I get a...

    Darrel had a special talent to understand things when they were difficult and not obvious. I learned a lot from his posts.



    I will send Melabs an email. They always respond to my technical...

    Also, PBP doesn't let you enable the PIC16F1454 USB internal voltage regulator. Below is the setting for the 18F4550.

    Re: PIC16F1454 Connecting To USB Doesn't Work

    Demon, don't give up. This is a very inexpensive chip for a USB project. I was hoping to use it for a few projects I have. I don't think that they implemented the USB part for this chip in the PBP...

    PIC16F1454 Connecting To USB Doesn't Work

    Hi,

    Has anybody tried to make a USB project with a PIC16F chip? I'm trying to make the PIC16F1454 work with USB, but I'm getting this error from PBP3 "USBIN/USBOUT/USBINIT/USBSERVICE commands not...
