nope, still doesn't work! we programmed it in the standard confguration for the 89LPC935, is it possible that something went wrong here?
now i've put a 89LPC936 in the MCB900, tried to read the device configuration and it worked, does this mean that the USB to RS232 isn't the problem? so we only have the problem with the previously programmed 935....is it possible that we managed to ruin it?

thanks!

edit : just noticed that we put our oscillator frequency in step 1 on 12MHz,  but when we read out the LPC936 it said 7.367 +- 2.5% is it possible that we programmed the LPC935 on a frequency of 12MHz while it was actually working on 7.367MHz and it stopped working ever since?

thanks for the tip but...

tried it and it still doesn't work, lowered the baud rate, still doesn't work...

jajaen.

hi,

I programmed a 89LPC935 using an MCB900 just a few hours ago, i was using FM3.50 and a USB to RS232 convertor.
the program was running fine but when i tried to reprogram it a couple of minutes later, i could not communicate with the MCB900 board.
I have tried everything suggested in "andy eyre's read first tips" but nothing seames to help, also upgraded to FM3.71 but that doesn't help either.
Even when i tried to connect the board later on by using a real RS232 it didn't help.
any suggestions please?

thanks!
