I've implemented the FET solution on some of my designs a few tim ...

What does your equipment do? What is it you provide that gets destroyed? If whatever you provide can get tagged to a specific individual at a specific time, then you could implement some sort of logge ...

Hi all,
I am re-staging a new PC and have an MPLAB question. In the past I've used EditPlus and the PCM/PCH line compiler. It provides most of the features I've needed (syntax highlight, autocomplete ...

Simple driver to send and receive a single data byte using inexpensive OOK wireless modules (315MHz, 433MHz) and RS232. Following the driver is example code on how to use it for transmission and recep ...

There is a CCS compiler bug in ver 1.140
This right there smells funny. You surely are not complaining about a bug in a version many years ago.

Many of your issues have been addressed by compiler ...

better option would be to use a quadrature encoder
great idea ... like use the right tool for the job

use the 1024 counts from a 10 bit ADC to create 1000 different frequencies
I'll beg to differ ...

a hardware filter should help, a median filter in software may also help. it looks like you are only getting the LSB jumping, so you could discard that as well.

Or even better; how about 1 cell and a step-up device like this one: http://www.pololu.com/catalog/product/798

That app note has a good explanation on the subject. I have my little spreadsheet which assigns each state a duty factor and then calculate total usage from there. The app note explanation just makes ...

I am pretty sure the pulse width contains the distance information. So I believe you need the following change:

You could do something like a round-robin style. As an example; test sensor1, once complete, test sensor 2, once complete test sensor 3; and repeat. For this, I would use a timer and start the timer e ...

I need to declare var_1 and var_2 as a long int to obtain 10 000 as an answer.

To add to what FVM illustrated. You do not need to "declare" one of the int8 variable as int16, but you need ...

What do you have for nominal battery voltage? What do you have for regulated voltage (i.e. voltage at output of regulator)? At what point do you write to the EEP (at power up, before power down, other ...

You can do it (as was suggested) either on the ISR or the Main. You already set a flag; so if you processed on the ISR you would be looking for "$" when the flag is not set; and for "#& ...
