P89LPC932 and serial communication, strange phenomenon

Following set: Two identical PCBs (my hardware design using the LPC932), one with the "real" MCU, other with connector adaptor to EPM900 board. My software runs smooth on the emulator. I always send...

os_tmr_call() callback does not work

I've got a simple project for LPC2138 microcontroller. In main() function I call os_tmr_create(10, 1); to create user timer and then just while(1); I've os_tmr_call(U16 info) function that is never...
