Re: K42 and Timer Interrupts

Thanks for the explanation.

I misinterpreted these paragraphs. My understanding was to have ASYNC cleared and use Fosc/4.

Re: K42 and Timer Interrupts

The SYNC block uses FOSC/4 as its sync clock, so it's difficult to use it if it's using FOSC/4 as its input source for counting too.

Re: K42 and Timer Interrupts

Sure it is. Inside the ISR, Timer 0 is stopped, reloaded and restarted.

I think is it obligatory to use Fosc/4. Unless I misunderstood the DS. Then why is it necessary to use ASYNC=1? Could...

Re: K42 and Timer Interrupts

Two things...

Since you're using FOSC/4 as the source, set ASYNC bit in T0CON1.

Also, when using 16 bit mode (MD16=1) you should always write TMR0H then TMR0L in that order so that the high...

Re: K42 and Timer Interrupts

looks like not reloading the tmr count every ms....... after first int, tmr counter looping from 0 .....???

I tried to setup the Timer 0 as 16bit timer, cloked by Fosc/4 with system clock at 64MHz.

K42 and Timer Interrupts

I wonder if anyone managed to work with DT-INTS18 with the K42 series chips.

The latest DT_INTS-18_K42c.bas file that tumbleweed posted (on this closed thread...

Companion Sheild

The entry level shield is labelled The Companion Shield. This is a PCB laid out in the pattern of a solderless breadboard. The holes are single sided, which means that components can easily be removed using solder mop braid, or a solder vacuum tool, if a mistake is made, or components need to be re-used.

The (PBP3) Companion Shield Manual iCan be downloaded from here

What is Amicus18?

Amicus is a multifunction development system inspired by the popular Arduino board, however, the Amicus board uses a Microchip PIC^® microcontroller instead of an Atmel AVR^tm type.

Comprehensive documentation and a helpful and friendly support environment, make using Amicus18 an easy and enjoyable experience for beginners and seasoned programmers.

Forum Moderator Mackrakit (Dave) very kindly ported the Proton BASIC Compiler code over to PBP3 and modified the original AMicus18 docuemts for PBP3 users.
