Both good suggestions above!

Have you looked at the data sent from the ADC chip to the micro with either an O'scope or a Logic Analyzer to verify that the ADC chip is sending the correct data, and that, therefore, the problem is within the micro?

Is the input to the ADC filtered and noise free, (at least for your initial testing)?

It is helpful to know, with certainty, where the problem originates, before trying to track it down.

Increase the stack.

Try slowing down the clock by adding delay.

Hello friends,
With past suggestions i have completed first task to get data from two SPI based 12BIT ADC, MAX189. Now, while attempting to receive uninterrupted values from the ADC's, I get a undefined jump in between the ADC value, like first ADC provide output as 3035, which remains for there with very slight change to 3039, then suddenly it jumps to a value of 1181, then come back to 3039. Throughout this process i never changed the input for ADC.
I am unable to find the cause to this problem?
Here is the code:
[code:1:ac55cb2941]$crystal = 16000000
$hwstack = 32
$regfile = "m32def.dat"
$swstack = 10
$framesize = 40
'$baud = 9600

Glad you got it working, it's a quite cheap and usable display!
I compared the datasheets of the controllers, but could not find any difference in control sequences/commands. It may be possible that they are not 100% compatible, even the datasheet of the ILI controller obviously differs from the real IC...

Hello guys! Any news about USB?

Hello

I have problem with tt_fonts
I use xmega128 and fonts Timesnewroman_10pt
when I use [code:1:ef1e6cd690]Lcd_tt_text "0" , 1 , 10 , Color[/code:1:ef1e6cd690] then display show 03 ,
when [code:1:ef1e6cd690]Lcd_tt_text "1" , 1 , 10 , Color[/code:1:ef1e6cd690] thendisplay shows 13
when [code:1:ef1e6cd690]Lcd_tt_text "Hello" , 1 , 10 , Color[/code:1:ef1e6cd690] thendisplay shows H33333, always shows only first letter and number

where is problem ?

Thanks

Hello,
I was able to install 2078.
Deep in the bowels of my PC I found the "install.exe" of that version - the installation went smoothly.
Thanks
Ernst

Hello dear reader,
so far no success in installing 2078
In a new folder I have 3 files: "bascom-avr-2078.lic" , "bscavrl.dll" (which I assume is the license dll) and "UpdateWiz.exe".
Upon starting UpdateWiz.exe a small window opens "MCS Auto Update Wiz 1.0.0.20", clicking "Setup" opens "Update Wizard Setup" asking for Proxy Data (all fields empty, except Proxy Port "0" and Time Out "0").
Clicking "Next" opens "Product Selection" with "BASCOM-AVR 2.0.7.8" in the select box. Clicking "Next" creates a small window "MCS Auto" with "Bad request" and upon "OK" I'm back at an empty "Available Updates".
Obviously I'm doing something wrong.
Any idea?
Thanks
Ernst

Configurate to 9 bit PWM.
