When you say serial, do you mean like UART?

Sounds like you may not be using the right library for the LCD.

Perhaps you want to run atoi() on the incoming data.

smeezekitty,

Thanks again from your support!
To answer you question. There is a place to solder a jumper but after comparing it with the opensource schematic and actual connection on the PCB I think it is not the Slow SCK settings.

I diverted to an old Arduino Diecimila with atmega328p Installed

and upload worked like a charm! Many thanks again for sharing your library!!!

Greetings from Japan!

You might try to see if there happens to be a firmware update.
I was considering buying one of those programmers but if it does not support software SCK that is kind of a let down.

Good luck from across the pacific

avrdude: warning: cannot set sck period. please check for usbasp firmware update.


That's not good. Looks like it does not support software SCK changes.

Does your programmer happen to have a jumper anywhere on it?

This usually comes down to a few problems:

* Wiring problem such as short circuit or target device not powered
* SPI clock too fast
* Wires are too long between the programmer and device
51  Community / Exhibition / Gallery / Arduino implementation of BSD robots on 128x64 GLCD on: November 05, 2013, 05:46:19 pm
This is an Arduino implementation of BSD robots


It uses the sparkfun serial 128x64 GLCD. I was too lazy to wire up a key matrix so I send the keys over serial.

I fixed it!
After resetting the 16U2 it showed up as an unknown device. I then installed the Arduino UNO drivers but it didn't work.
It gave me a Code 10 in device manager.

So I downloaded Atmel FLIP DFU programmer and installed the DFU drivers which installed without error.
I then load FLIP and successfully connected to the 16U2. I then uploaded the hex file from the Arduino folder and then unpluged and replugged the board.

Finally I reinstalled the UNO drivers. Sure a lot of work but it is fixed now.

Just tried another one (albeit loose fitting one) and no result smiley-sad
New information:
I jumpered the pins to reset the 16U2 and windows gives me the device connect sound and pops up "Windows needs to install driver software for your Unknown Device"

Edit: Oops mine has a 16U2 not 8U2

Hi

This topic is quite old but i think someone can help me and maybe the topic can be useful to other users...

I have the same issue with IDE 1.0.5 and arduino UNO. Sometime when VERIFING  my MBP (late 2008)  reboots instantaneously.

I read that can be a power supply matter, but i think for me is different because it reboots when verifing...


Thanks  and sorry for my english

Bye
If it happens when verifying my guess would be CPU overheating.

I was working with an Arduino UNO and a spark fun Serial GLCD connected to the TX-> pin through a 1k resistor.

I had a intermittent power issue with the LCD so I fiddled with the wires although I don't think that anything shorted.
I then made some changes to the code and hit upload only to be greeted by "COM7 not found"

So I unplugged the Arduino and plugged it back in. Windows gave me a popup "USB device not recognized"
I tried another USB port an this time got nothing. Not even a change in device manager.

Removing the LCD display did not change anything either. When plugged into my Linux laptop there was no response from dmesg.
Strangely enough when I plugged it back into my Vista desktop and connected the LCD screens power connector it gave me another USB device not recognized popup so I tried the same thing on Linux and after several times dmseg spit out
Code:
USB 5-1: new full speed USB device using uhci_hcd and address 21
USB 5-1: device not accepting address 21, error -71
hub  5-0:1.0: unable to enumerate USB device on port 1
Writing to /dev/ttyACM0 (which was assigned when it was working) succeeded and even made garbage display on the LCD but attempts to change baud rate caused "Inappropriate ioctl for device"

I don't see why it failed. Did I seriously fry a third serial to USB convert chip?

You will need to upload the code before disabling reset.
WARNING: You will need to use a HV programmer to program the chip once you disable reset.

There is a good chance you have the fuses misprogrammed
58  Using Arduino / Microcontrollers / Re: core13: An Arduino core for the Attiny13 *testers wanted* on: September 14, 2013, 06:11:39 pm
uh how complicated. can't i just download the core and put it in the hardware folder like any other ? or does it need extra files.
I know. The arduino boards.txt are horrendous. But that's how it works.
I have alot of trouble with it myself
59  Using Arduino / Microcontrollers / Re: core13: An Arduino core for the Attiny13 *testers wanted* on: September 11, 2013, 10:56:52 pm
my IDE does not pick up on the new board configs, I down loaded from sourceforge.

when there will be 019 version? required internal voltage reference
also tested people with ARDUINO.RU. Analog input only works on RB3 pin attiny13. maybe we're doing something wrong?
Internal voltage reference should already work.
I will try to debug the analog input soon. It is one of the hardest part to work on.
