Title: 50$ robot using an AVR programmer with USB not serial
Post by: E.Man.Lava on January 19, 2008, 09:33:09 PM

What program do i use when making the 50$ robot using an AVR programmer with a USB connection instead of a serial connection?  ???

same program


remember whether its USB or serial all its doin is transferring the program from computer to chip. Its the program on the chip thats the same no matter how it got there

I know but on the tutorial it says to transfer the code from AVR Studio to the microcontroller via PonyProng2000 serial port connection, so what software do i download to transfer the code from AVR Studio to the microcontroller via USB ported AVR programmer  :-\ ?

you get a usb to serial converter.
your computer will think it's a serial post and then use ponyprog as normal.

bad thing, is that usb->serial cables cost about $30

you  might want to look at the arduino from www.sparkfun.com
it's only $34

you mean connect USB programmer to USB port?

umm I dunno , check online \

I'll look online as well and post anything if I find it

you should be able to select your programming hardware in the software menu as USB programmer

I think that should do it

It should make sense that you could configure the software to recognize a USB programmer

I tried this and it says connection failed, does that mean that there is a problem with the circuit board  ??? ?
if there is in fact a problem with the circuit board, how would i fix it?

Here are some pics of my circuit board/microcontroller

(http://C:\Documents and Settings\John\My Documents\My Pictures\circuit board)

does it look ok?  ???

P.S. can you see the pic?

they go to the photoresistors.

if you're still having a problem connecting, I'd get a multimeter and chech the whole board for any shorts

how exactly do i use a multimeter?  ???  :-[

select the ohms functin. if something is supposed to be connected there should be little resistance.
if somehting isnt supposed to eb connected, but is. you have a short.

but be aware that the 5v regulator and the mcu let a little current to come through
