Thanks to all of you, that really helps a lot!

Oh my,

Shame on me and RTFM i guess.
My PIC indeed has hardware USART on board, should have read the manual.

Just had to set the baud rate and such and of we go...

I will never ask stupid...

Hello,

I need to send serial data asynchronously using a frame format of 1 start, 8 data and 1 stop bits.

I've been looking around in the manual and this doesn't seem to be supported.

Am I...

Hello,

I was wondering why it isn't possible to search for three letter terms. I know this reduces overhead in many situations, but when you try to run a forum with information about a programming...

Hi,

I will need to add a real time clock to an upcoming project and have been looking around for an RTC IC at the Dallas/Maxim website.

They have so many, which is the best and easiest to...

I don't know for sure,

since i changed my computer I should digg out the old schematics somewhere. But I'm pretty sure that there where pulldown resistors in my design. It's never a good thing to...

Bummer...

It's always these rather stupid mistakes you have to watch out for. I do recall i did exactly the same thing some time ago with a LM35 sensor, so it aint the first time this happened to...

Don't bother everyone, I didn't notice the line saying (BOTTOM VIEW) at the base of the IC lay-out, thus GND and VDD where connected the wrong way. Thank god it still lives and functions now.

Hi,

I'm trying to use code I found here to get a reading from a DS1820 device. Whatever I try, this always gives me a 'not present' error. But the brand new 1820 is right there and connected to...

hmmm, I figure there's also the voltage drop over the transistors. about 0.6 volt each.

So the resistors for blue and green should be 10 ohm and for the red should be something like 82 ohm.

Thanks for the efford Keith.

After a bit of sleep and with a cleared head I made up this:

Swapped PNP and NPN transistors...

Dude! You're so right.

Lack of sleep makes pax go crazy.

Thanks a bunch, i'll rework it after some sleep... or coffee...

Hi there,

I'm thinking of building a RGB LED driver for 8 LEDs. I want to use a PIC16F777 for this task as it has a very convenient 3 hardware PWM channels.

I've made a little schematic, but...
