unfortunately the burst is difficult to trigger on my O'scope.
I would appreciate some hint to get data into my 24 registers (ideed not very elegant solution..but...)


Hi Edgar,
The real trick is catching the TWO bursts of 24 bits, which contain DIFFERENT information, and making sure you get the RIGHT 24 bits in the right places.

What you have is OK to get the data, once you have the sequence sorted out.

You can differentiate the packets by the length of the clock of the first bit of each word, but thats VERY hard on a naked 8052, with 90Khz signals. I wanted to use the serial ports, but I couldn't find a dual serial port fast variant with ISP/IAP FLASH from local sources. My code is running on an atmel 89C52RD2
