160 Baud aldl scantool

hi,
thanks for your fast replay i can blink a led and also i can display text on lcd that what i test before

I think the next step would be to get a chip with hardware serial (USART) and work with that. The USART is not to much different than using SERIN2, just seems to be a bit more useful at times.

If you can find out exactly what the ECM baud is and if the signal is inverted or not. Can you connect a PC to it? Then we should be able to see what you have to work with.

Do you have the actual ALDL160 protocol standard?
You can read it at 160 baud all day, but without the protocol or knowing how the data is formatted, the numbers are going to be jibberish on the LCD and useless.

And, for me anyways, a Google search on '160 baud aldl' brings me a whole load of decent links with hardware, software, and at the very least, a base to work with....if I was building an ALDL reader....which I'm not....

what chip have serial (USART) to start working with.
ECM baud rate 160 Baud
there is a lot of circuits which can be interfaced with PC and using special software we can see these data e

during my search on internet i found some one make circuit to do that using pic16f84 and lcd (20*4) but the one who design this circuit place assembely software for the pic but i am not good at all on assembely

Use the Parametric search at www.microchip.com, find one with a UART/USART on it, pick and chose which one you want.

Well, email them, maybe they'll share their code...maybe not...
that's the breaks...and without knowing what data is where in the data stream, you may as well be receiving random noise.

hi,
please find attached file for published aldl display circuit using pic16f84 and lcd display u will find also attached assembly program if u can help cause i am not good in assembely to convert this program into picbasic ????

I could help, but my time/effort cost more than FREE...

However, if you attempt to convert this over to PBP yourself, and you have problems, I am absolutely sure that a number of people here on these forums would be more than happy to assist in the endeavour.

so u will help me to do that or ????
