hi @ll, I use 89LPC932 and µVision2 V2.20 with C51.exe (V6.21)? I haven't found LPC932 in the Device-Database, so i added Device-Data manualy in to the Database. I have copied the data of LPC762 and modified it to LPC932. Can i work with this constallation or should i update the Divice-Database, the compiler Version and the needed *.dll's? for the second case, where can i exactly found this stuff? thx Uhland
