Pic18F14K22 with USB MCP2200 - pietervanwyk - 2013-06-24
I will appreciate help with this.
Spent days and can not get the bootloader to work at all. With a C program, comms Tx and Rx works and the MCP2200 Usb to serial converter works 100%.
I have tried just every option with clock speeds, configurations, etc. I also tried it with the latest bootload version.
The Osc is running 64000000 with the PLL but the code gives an error and I therefore switch off the PLL to run 16000000 hz.
Here is my user setup, changed to enable the MCP2200 and a led, tried with and without the OSCCON setup:
USER_CODE.INC:
Code:
; UserInit()
; Description: this is executed immediately on start-up before the boot loader code

RE: Pic18F14K22 with USB MCP2200 - Mikael Gustavsson - 2013-06-24
You need to configure the RX pin to be digital, put the code in the UserInit macro:
Code:
bcf ANSELH, ANS11RE: Pic18F14K22 with USB MCP2200 - Mikael Gustavsson - 2013-06-24
Where are the configuration bits?
RE: Pic18F14K22 with USB MCP2200 - pietervanwyk - 2013-06-24
Dear Mikael, please pat yourself on the shoulder...
Twice please!
bcf ANSELH, ANS11
was the problem....
Still will not work with PLL= on (64000000hz) but it may be the chip config.
Thank you!
RE: Pic18F14K22 with USB MCP2200 - Mikael Gustavsson - 2013-06-24
Great. Do you enable the PLL?
Code:
bsf OSCTUNE, PLLENRE: Pic18F14K22 with USB MCP2200 - pietervanwyk - 2013-06-24
The PLL enabled (64000000hz) does not work.

I am trying to run PIC18F firmware on PIC18F14K22 too.
I have changed settings.inc file like this;
