UBW32 and Pickit 3 enough?

[funlw65]

Thank you David for the solution! Hopefully, @atmega8 will figure it out!

[Atmega8]

Thanks to all,

with this Settings the LED blinks 10-12 times to slow ;-(((

that is because you have to change David's settings, with your hid bootloader settings (the ones I gave you)

[Jerry Messina]

Maybe this??

Code: Select all

    public config FPLLODIV(FPLLODIV) = {DIV_1}
    public config UPLLEN(UPLLEN) = {ON}         
    public config UPLLIDIV(UPLLIDIV) = {DIV_2}       
    public config FPLLMUL(FPLLMUL) = {MUL_20}       
    public config FPLLIDIV(FPLLIDIV) = {DIV_2}       
    public config FWDTEN(FWDTEN) = {ON, OFF}         
    public config FPBDIV(FPBDIV) = {DIV_1}         
    public config WDTPS(WDTPS) = {PS1}         
    public config FCKSM(FCKSM) = {CSECME}       
    public config OSCIOFNC(OSCIOFNC) = {OFF}         
    public config POSCMOD(POSCMOD) = {XT}         
    public config IESO(IESO) = {ON}               
    public config FSOSCEN(FSOSCEN) = {OFF}       
    public config FNOSC(FNOSC) = {PRIPLL}
   
    ' set config for program...
    config FPLLODIV = DIV_1         // PLL Output Divider
    config UPLLEN   = ON            // USB PLL Enabled
    config UPLLIDIV = DIV_2         // USB PLL Input Divider
    config FPLLMUL  = MUL_20        // PLL Multiplier
    config FPLLIDIV = DIV_2         // PLL Input Divider
    config FWDTEN   = OFF           // Watchdog Timer
    config FPBDIV   = DIV_1         // Peripheral Clock divisor
    config WDTPS    = PS1           // Watchdog Timer Postscale
    config FCKSM    = CSECME        // Clock Switching & Fail Safe Clock Monitor enabled
    config OSCIOFNC = OFF           // CLKO Enable
    config POSCMOD  = XT            // Primary Oscillator
    config IESO     = ON            // Internal/External Switch-over
    config FSOSCEN  = OFF           // Secondary Oscillator Enable (KLO was off)

I think that matches up to what funlw65 said the bootloader sets it to.

[Atmega8]

Hi,

i don't use a bootloader.
I compile The code with firewing and burn it with Pickit 3.

[Jerry Messina]

yeah, but if those settings get 80MHz for the bootloader, they should work ok without it, too.

[Atmega8]

@funlw65

Settings from which forum?;-), which post?
Who IS who what IS what....

[Atmega8]

Please can Someone explain the Syntax for example of:

public config FPLLODIV(FPLLODIV) = {DIV_4}

and the corresponding

config FPLLODIV = DIV_4 // PLL Output Divider


THX

Just try what Jerry Messina gave you just now (is the same with what I gave you but adapted to Firewing).

But lets clarify some things. The PIC32 must "receive" a configuration from you, just like an ATmega8. When on ATmega you set a bootloader (or any program), that ATmega needs some configuration fuses in order to work. Then your programs don't need a configuration anymore.

If you use a bootloader for your PIC32, that configuration is already written (when you burned the bootloader first time) and you will erase/write just a part of your FLASH - the PIC32 will remain programmed with the old configuration, don't needs you to write it again. If you don't use a bootloader, every time you write a new program, you erase the flash entirely so you will need to write the configuration again, with every new program. The configuration will be always identical (doesn't matter what program you wrote inside, a bootloader or a simple program) because it is specific to your hardware that will not change (your crystal is soldered to the board, etc.).

Just try what Messina wrote.

I think I just wrote the most abiguous explanation ever ...

Hi,

"Just try what Jerry Messina gave you just now (is the same with what I gave you but adapted to Firewing)."

Thank you funlw65, it works and now with the correct frequenc!!


@ David
You told me to Change the Compiler from microchip32 to firewing32 for better code optimization.
But after doing this, the compiler throws an error.
Don't know what he is complaining about

I cannot copy and paste Errors from your IDE; very unconvenient;-(
