Yeah, adding a hardcoded adc-channel selection would be easy. Nicer would be auto-detecting the used channel if possible.

I don't understand what kind of hardware you have there...

ADC0 and ADC2 are not connected to anything (on the unmodded board)?

ADC1 is the keypad input... and you've short-cut it with ADC0 pin?

Why did you need the extra resistor? Is that because short-cutting ADC0+ADC1 somehow changed the voltages? Or is your keypad board different - ie. which resistor values do you have on the keypad board? 1K, 2K and 4.7K ohm?

And is there a pull-up resistor on the ADC pin on mainboard, with how many ohms?
I don't remember how that's wired on my own mainboard, but I guess there must be some pull-up (since unused ADC pins are floating somewhere between VCC and GND).

Oh, and what firmware did you have on that board originally? Or was it the 1024x600pix firmware you posted earlier? My firmware doesn't properly support that resolution though.

And what is the yellow thing on the photo, is that a LED? A PCB photo would be nice too, and the TFT display part number (and info on size/resoltution).

For downloading: Best start here, with the first page, http://remont-aud.net/dump/car_audio/ca ... nitors/356 and download all AMT6xx related files (including AMT628 or AMT629 or whatever) (ie. use your browser's search-in-page to find anything with "AMT"), and then continue at second, as far as you can get (in total there are currently 5 pages (the older pages have fewer AMT chips, so maybe 50 points are enough to get through all pages).
Important please include some info what you have downloaded where from. In the two files I have posted above (for AMT630 and AMT629), I've included an extra txt file (inside of the archives) with the URL where each file was downloaded from, and copy/paste of the text on that page (showing only the latin/ascii part though). Adding that info will probably make downloading a bit more time consuming, but it could be quite valueable to have that info included.

five files per day.
Why No$x51 do not understand asm51 command CJNE ?

Thanks! But... oh no, you did it! You didn't include the URL's and other text/info ; (
Hmmm, it looks a bit as if the first 5 digits of the zip/rar name are matching up with the last 8 digits of the URL?
So this http://remont-aud.net/dump/car_audio/ca ... -1-0-57157 would correspond to file 57157_AMT630A.rar [13.79 KiB]?
On the other hand, looking at two other URLs, http://remont-aud.net/dump/car_audio/ca ... -1-0-57877 and http://remont-aud.net/dump/car_audio/ca ... -1-0-56231 - I can't find files for them.

No$x51 supports two asm syntaxes, ".native" and ".nocash", in the latter one, CJNE is called JNE (and it differs on using round/square brackets and # prefixes). The syntaxes are described in CPU Microprocessor chapter.
Btw. did you read my previous post, with the questions about what hardware you have?

Do not worry! I have prepared a file to organize the data.

About hardware.
I have small 4.3" car monitor. Its native firmware - WD-888-V1.0 CRX441.zip
Its keyboard have 3 buttons with resistors 1k, 2k, 4.7k, but in another order and another ADC input. Pull-up resistor 12k, so voltage on input of ADC change in another range. I corrected your firmware and keyboard works good. Yes I added power LED, because blackscreen idle mode and autoswitch to second AV input annoyed me. TFT panel 480x272 size, marked on te connector ZNL043T702-P40.
It remains to solve two problems:
1. Settings are not saved. May be your firmware do not work with my flash chip? I tried three different chips - no result :cry: Which chip exactly works with your firmware? Now I changed presetting in your firmware to my needs.
2.Not sure it possible. Can AMT630a zoom picture in small limits (3-5%)? The fact is that all picture does not fit in screen. I need "underscan" picture. Pleases that menu item "signal decoding - pal/ntsc/pal60" change size of picture.

And yet one questons: How Nocash works with local/global labels as is "@@...", what determines its scope area?
