To get volume control, you can multiply your PWM value by a number between 0 (lowest volume) and 0xff (highest volume), then output the high byte of the 16-bit product.

You could read a potentiomet ...

From 18F46K22 data sheet: Full 5.5V Operation – PIC18FXXK22 devices. I've used the 18F46K22 at 5 volts, it works very well.

I've had good luck with MDBUS by Calta Computer Systems.

I use B&B Model 485USB9F-2W converter that plugs into Windows USB port and provides two-wire RS-485 connections.

You will not be able to accurately select 1000 unique values with a single-turn potentiometer. Even a small fraction of one degree of rotation will change your values by several counts. In addition, ...

Could be stack usage varies with compiler version, or the compiler command line switches might be different between the two versions. Possibly an array pointer overruns its allocated memory area and ...

The syntax is very similar between PCD and PCH compilers. I would download the latest PCD reference manual from CCS, and look at the ADC examples. Start with Functional Overview - ADC. There are li ...

I don't know what a "smart prox5" programmer is, but it sounds like it might be wrecking your chips. I have programmed the 18F parts many hundreds of times (using Microchip's PICSTART Plus ...

I have had good luck with batchpcb.com. I found them through Sparkfun. They are great for prototypes because there are no setup or tooling charges. The boards are very nice quality. I have been us ...

You could try swapping your two serial data lines (data+ and data-). This should perform an inversion just like your inverter chip, without requiring the inverter chip.

I had to download a new acrobat reader, then quickly found the "reset_cpu()" instruction in the ccs manual. It works like a charm. Thanks PCM programmer!

Thanks for the PDFs. I'll check 'em out.

I'm using PCH 3.249 with the PIC 18F4620 and I would like to be able to use an instruction that would cause a reset just like hardware /MCLR reset. Is there such a thing?

Thanks in advance, I've l ...

Agree with FvM. You would be best to use a modulator/demodulator IR transceiver instead of generating the modulation frequency with the PIC. The data bit times are long enough that you can toggle a ...

If you are using the CCS compiler, you came to the right place. If you are using a different compiler, this forum will not be helpful. There are a lot of examples of programs for 7-segment displays, ...
