Hello,
I ordered a MegaDrum kit from Synthex. After assembling I started testing it.
I ran into 2 problems.
The first is really easy to fix I guess.
I`m running Win XP lite edition and it doesn't contain the usb drivers.
Does anyone know if it's possible to download these drivers somewhere ?
The second problem is a bit harder to fix I guess.
The lcd won't function propperly.
I get a < on the lcd and nothing else.
I checked all the connections and components and they are all good.
I also checked for shorts but everything is right.
The Atmega 32 has a nice stable 5 v (measured with osciloscope)
But I think the problem is with the crystal osscilator. When I measure pin 12 and 13 I get an dc voltage of 850 mV (also measured with osciloscope). I tried replacing the crystal and I also tried another Atmega 32 but both give the same problem. I also replaced the 2 22pF capacitors but it didn't solve the problem.
The crystal is 16 MHz.
And the kit is Synthex all in one v2.8.
The osciloscope is fast enought to measure the 16 MHz so that shouldn't be the problem.
Thanks in advance.
edit:
Nevermind the second problem. Tried a third Atmega and it works... Now I only need to find some drivers for Win XP lite.
