Re: Question regarding Interrupt handler - No DT_Ints used.

It's probably good to be aware of the minimal context saving done automatically, but for the code in question it's not using any computed GOTO's so I think you should be safe with the code pretty...

Re: Question regarding Interrupt handler - No DT_Ints used.

I would be pretty cautious about that. pbp code is full of goto's

Re: Question regarding Interrupt handler - No DT_Ints used.

Section 6.5 (page 39) of the PIC10F322 Data Sheet declares the only context saving it does is saves the PC. Example 6-1 spells out the minimal Assembly code required to accomplish that feat (note,...

Expanding my Horizons

Recently I decided to learn to program in C, and learn about the 16-bit PIC processors. I bought a couple of books, the Microchip Explorer 16/32 Development Board, the PIC24FJ128GA010 mezzanine,...

Re: Question regarding Interrupt handler - No DT_Ints used.

Thanks for your input tumbleweed. What you said coincides with what I have been able to gather by looking at the LST file. As Richard pointed out, I may have been stepping on system variables but...

Re: Question regarding Interrupt handler - No DT_Ints used.

There's nothing wrong with saving all that stuff, but that's a lot of bother for what you've got going on.

If all you do is simple sets and tests with port bits and bytes like you have then you...

Thanks for the advice pedja089. I couldn't make it work as you suggested but I did manage to get it to work this way:

Re: HT16K33 LED Controller

I'm not very good at this but since no one else chimed in here's my thoughts. I was looking at the data sheet and I don't see this as a settable mode. Page 61. Most people don't bother with an...

Re: Question regarding Interrupt handler - No DT_Ints used.

Hi,
You could try to use only ReEnterPBP.bas to take care about saving and restoring variables.
So just call
SavePBP_H:
After saving status wreg etc,
And before you exit interrupt call ...

AMICUS

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.

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

GPS Shield

The Amicus GPS shield contains a multi channel GPS receiver, as well as a 16k byte (128 kbit) serial (I2C) eeprom, and a 3 Volt, 12mm battery socket in order to maintain the receiver's built-in RTC (Real Time Clock).

Available in our on-line store
