Re: 12F675 vs 12F1840

Hi, Ioannis,

I'd have a look to internal registers PBP default settings ( the PBP default Config file ) ... as you overwrite most of them ...

just an idea ...

Re: HID USB Multimedia Keypad

Give it a try and report your results. I use HIDMaker for USB stuff. The last time I had to create a USB project (this time using XC8), nothing compiled. I got numerous errors. I tried generating...

Re: 16F1705 internal Opamp woes

Hi Tumbleweed,

You are a star, thank you.

I don't know how I missed that bit, correcting it saw the Opamp spring to life... in fact I tried a bunch of combinations with TRIS and ANSEL and it...

Re: HID USB Multimedia Keypad

So will this work in PBP3?
I want to have such a keypad, and ashamed to have to use Arduino Pro Micro :D

Re: 16F1705 internal Opamp woes

OPA1CON = %1100000 ' Opamp 1 Enabled, SP set.

Isn't that missing a bit?
Try

OPA1CON = %11000000 ' Opamp 1 Enabled, SP set.

For OPAMP1 you have

Re: 16F1705 internal Opamp woes

Hi Richard,

I knew you'd be the first to respond :)

I've been monitoring the output (pin 8) throughout the testing and it doesn't go above ground at any stage. Ultimately I want to process the...

Re: 16F1705 internal Opamp woes

are you seeing this voltage at opamp out pin with a meter ?
your description is not clear whether the opamp is not working or the adc measurement .
working with opamps with inputs near rail...

16F1705 internal Opamp woes

Hi All,

The title says it all. I'm trying to utilize the PIC's internal opamp rather than a separate opamp to measure load current on AN6 but I cannot get it to work. I've RTFM so many times I...

Re: 12F675 vs 12F1840

Most strange is the 32 vs 4 MHz clock. Lower clock needs more code space!!! I expected the oposite.

Re: 12F675 vs 12F1840

I shouldn't but for the sake of the very strange case I will. On both the chips the code is the same except for the port access. Everything else is identical.

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
