LCD problem

[alkama]

Hi,
I programmed my PIC18LF2550, and i think it's ok.Then i use MCT to update firmware, this is the log:

21:25:23 INFO: Initialization started
21:25:23 INFO: Configuration file read successfully

21:26:01 INFO: Sending firmware...
21:26:19 INFO: Firmware was sent. Now closing...
21:26:19 INFO: FIRMWARE UPDATED!

The LCD shine, but there are no any mark on this.

All connections with PCB are ok.

Where is the problem?

By the way, should megadrum be showed in 'My computer' when it be connected by USB?

Thanks.

Have you at all looked at this sticky topic?
MegaDrum FAQ. Read it before posting in this forum!

I have read this, voltage between LCD pin 1 and 3 is 0V.
And other question?

I have read this, voltage between LCD pin 1 and 3 is 0V.

Is it good?

And other question?

What other question?

[alkama]

It is not good. Should be between 0.5 and 1.5V

I wonder why the LCD topic is not sticky. Was it not before?

What other question?

A question from the "support staff" I presume

[Firelord]

Also I think that the firmware might not have been updated properly.

alkama, did you program ATMega with a bootloader using a parallel programmer + PonyProg prior to attempting to update the firmware via MCT?

[alkama]

Can i check it however?

The LCD topic (and several others) is referenced from the sticky MegaDrum FAQ topic. Too many sticky topics and you will only see them on the first page of the subforum.

Yes i do everything from section 'Programming Megadrum bootloader' from website.
