Kit as LED cube not seen by serial port
I have built an LED cube using the minipov kit. The test program that was preloaded on the chip works fine. I think all my solder joints are good. I am connecting directly to a serial port, but it is not being seen. Would the LED's light if there were a problem with any of the components? I am a noob, so how would I check them?

Re: Kit as LED cube not seen by serial port
Is the board powered on when you connect it? It needs to be on for programming.
If you have followed all the steps here http://www.ladyada.net/make/minipov3/software.html and it still doesn't work, post some clear photos of the front & back of the board.

Re: Kit as LED cube not seen by serial port
Thanks for the very fast response. It is powered on.
This is what I get
C:\>make program-ledcube
avrdude -p attiny2313 -P com1 -c dasa -U flash:w:ledcube.hex
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
make: *** [program-ledcube] Error 1
I will post photos as soon s i can get them taken

Re: Kit as LED cube not seen by serial port
Other details that might be helpful:
Operating System?
Regular serial port, or USB/Serial adapter?

Re: Kit as LED cube not seen by serial port
Would the cube still work, like mine does, if all the solder joints or components were not good?

Re: Kit as LED cube not seen by serial port
If the only bad solder joints were between the serial connector and the microprocessor, it would work just fine.

Re: Kit as LED cube not seen by serial port
Pin 4 on the top looks like it might be a cold joint. Those RS-232 pins need a good hot iron.

Thanks. I think I have resoldered every joint now and it still is not recognized. Any other advice?

Re: Kit as LED cube not seen by serial port
Do you have the correct COM port configured in the makefile?
What settings do you have on the COM port? Speed, data bits, stop bits and flow control?

Re: Kit as LED cube not seen by serial port
I believe so. It was originally set to com8 and gave a different error when I tried to connect so I set it to com1. I am pretty sure the settings are all default, 9600, 8 bits, no parity, 1 stop bit, no flow control

Re: Kit as LED cube not seen by serial port
Do any changes need to be made to the port settings? I am still not having any luck

Those are the same settings I use to talk to my minipov.
Have you used the COM port to talk to any other serial device?

Re: Kit as LED cube not seen by serial port
No, this is the only device I have tried. I did try it on 2 different machines with the same results.
I want to get a mini pov kit as well, but would like to work before that.
