RA5 is a regular I/O pin, except that the output driver is open-drain. I was bitten by the same RA5 problem with the 16F627A a few years back. RA5 is not the same as MCLR on those parts.

However, I do not see a whole lot on how to set them up. Especially getting the address set and how to send the different commands. Can I get some more details on that please?

I saw the pic of the printed board layout, are you allowing people to have the circuit design you created copied for personal use? Also, have you considered expanding the circuit to do something like PC control via usb? (Just curious) Hello, I’ve been looking on the net and I have a somewhat self-ish question.

I'm sad that cc isn't still up, but that's life, and at least it let me discover the stuff that you're doing now with the LEDs and such which is awesome. A while back i did a collaborative project with a friend that knows much more about microcontrollers than i do build the hardware/circuit board to interface with a program called Max/MSP which allowed for infrared sensors to control music and video &c, and it's always good to see projects like that crop up in other places and in unique ways. keep up the good work. for the record, i was thinking about Connection Cloud today and was wishing that it was still up somewhere, and that led to wondering if maybe it was in a different form which led to a search which then led to finding your blog.

I give them a adress with a terminal porgram.... but if i let the visual basic program run for a long time... after a while one by one they stop with working.... ... is see the rs232 still sending data too the PCB, but the don't respons anymore.... do somebody know why? a bug in the program? the only to start them again, is stop the movie, turn of the power for al the pcbs,and turn the power back on, start the movie again.... and than it works for a hour...or something Help somebody... I have build it too, and it works…. I give them a adress with a terminal porgram….

but if i let the visual basic program run for a long time… after a while one by one they stop with working…. … is see the rs232 still sending data too the PCB, but the don’t respons anymore….

do somebody know why? a bug in the program?

the only to start them again, is stop the movie, turn of the power for al the pcbs,and turn the power back on, start the movie again…. and than it works for a hour…or something

Help somebody…

Have you considered combining your multicolored jewel with some of these low-cost RF receivers?: http://www.futurlec.com/Radio.shtml $6 for a receiver or $7 for a transceiver. I'm going to have to peak at your code and see how the timing works out for 12 pwm channels on a single chip! Nice work! This is some great eye candy!
