1  Using Arduino / Displays / Re: ST7920 Interface Question on: July 25, 2012, 07:13:43 am
at the moment i am using the SPI interface with a ST7920 with the u8glib.
but it is to slow to update the whole display.
is there a function i can use to update a part of the screen (not the whole frame buffer) to speed up things?

the function i use now is drawPixel(); and i draw a horizontal wave form, so its a line of 128 pixels.

thanks! now it works (-:

there were 2 of these files: avrdude.conf.bak and avrdude.conf
so i changed both.

maybe its good to include this in the readme.txt

hi,

i trying to get my attiny85 to run at 8mhz. but i cant get it to work..

when i upload the blink sketch at 1mhz it will blink like it is supposed to. but when i upload it at 8mhz it will blink much slower. so i assume the attiny thinks it is running at 8mhz but it is actually running at 1mhz..

i read somewhere in this threat that you need to set the fuse buts by burning the bootloader. but this is not working for me, when i do i get this error message

Code:
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avr_read(): error reading address 0x0000
    read operation not supported for memory "lock"
avrdude: failed to read all of lock memory, rc=-2

i am using the arduino as a isp programmer..

well that's a matter of taste i guess.

thanks! and also thanks for the video input in the tvout lib, it would not have been possible without it.

if you send VGA you can put this inbetween:

should work fine.
14  Using Arduino / Displays / Re: TVout Colors on: July 11, 2011, 03:24:53 am
would it be possible/difficult to convert the TVout lib into the VGAout lib?

it could be like this:
00 = R
01 = G
10 = B
11 = ?
