HPWM on 16F88

[Darrel Taylor]

If you are using MPASM for the assembler, defines need to be all uppercase.

    define CCP1_REG PORTB
    DEFINE CCP1_bit 0

Hello Darrel,

nice you took a look at my childish problem.

The config files you mentioned were in the upper part of the program
do I have to put them in the .inc file? I´m confused.

And i was so frustrated I wrote code that used Portb.0 as switch
inside my simple program because I feared the chip was blown but it works.

it is just: I can´t get portb.0 as HPWM output AND the normal LCDout application at once. The LCD is the reason I can´t switch the port. got the boards already.

sream, howl, and so on

Try to set your fuse like this:

@ DEVICE PIC16F88, CCPMX_OFF

where:
0 = "ON" CCP1 on RB3
1 = "OFF" CCP1 on RB0



You also need to set a register:

CCP1CON = %00001100 'Select PWM Mode

Instead of using HPWM, try this:

PWM PORTB.0,speed,1000

You won't need to declare/define T2CON, CCP1CON, PR2 and CCPR1L.

PS: I'm using MCS
