... *snip* ... *snip* Not a terrible idea... The PicAxe is a decent alternative. Really, any MPU will work. Each has their quirks, though, and the PicAxe is no...
... If you want a really decent programmer, try the MicroChip PicKit 2: http://www.microchip.com/pickit2 It is relatively cheap ($35), supported and easy to...
For what it is worth, the Picaxes that might work for you are 28X1 0-12 inputs 9-17 outputs 0-4 ADC 20MHz 40X1 8-20 inputs 9-17 outputs 3-7 ADC 20MHZ Both have...
I was thinking of building a solar charging station with a couple of lead acid batteries. I know there are commericial chargers available and was thinking of...
That was a good article.I didn't realise there might be a problem for the overcharging. I was going to use a couple cheap solar panels. they only handel about...
From what I can tell, Basic Stamps don't do "A/D" (analog to digital) conversion, which is what you need to do, to read voltages. I suggest you take a look at...
... I use PicBasic Pro -- Highly recommended for the programmer wanting to program in the BASIC language. Also note: the free demo version can accomplish most...
The Picaxe series chips, being PICs with a bootloader, also have A/D built in. And the BASIC programming software is free for the download. And no programmer...
I'm looking for someone who has used the pic12f629 and programmed it using C. So far I've had a problem doing a simple turning on and off ports. I'll save...
Although the "full" C compiler from Microchip must be purchased, you can download the student version for free. This version has some of the optimization...
Thanks for the reply. I have now written/converted C code into ASM code for both the HID and CDC type devices. Another question. Is/can the HID type USB be...
I know I can get a PIC to control a switch like a CD4066, but can I simply use some built in function of the PIC to do the switching internally? That is, say I...
Hi, You have some analog channels (depend on PIC type) wich you can use for achisition and in some configuration you can provide by some specials pins outside...
That will work... but there is a problem. I don't know of a PIC that has a real analog D/A output (anyone else know of one?). You can make an analog D/A by...
I am not familiar with using an averaged PWM for D/A output, but have seen Microchip AN538 - Using PWM to Generate Analog Output, which uses a low pass filter...
I didn't see the first post, but.... if you have several Output ports then a simple 2R-ladder can be built. Attached is a JPG of a schematic of a 2R ladder...
Yes, the 2R ladder would be a good solution for the D/A, but it takes up a lot of real estate. What I was trying to do was get rid of a CD4066 switch by...
I thought I did attach it. I will try again. and...... you are correct it does take up some real estate. (attaching the file...wait.....wait.....) OK, it does...
OK, can you believe that. It still didn't attach. Trying again with a different browser!!!! I am following the whole SWITCH thing now. Yes, as was stated...

Sorry all, Yahoo took my spaces and put "&nbsp" in its place. Short and simple, the BCD binary is MSB on the left to LSB on the right. Later, (again) Keith...
