    assert.hHi,

    you can copy the assert.h file from the driverlib library into the scr folder of the library.

    (i have also attached the file)

    Note: you will see another error when compiling as the MSP430 does not do any RTOS or task switching.

    So this line in U8x8lib.cpp

            //yield();

            Task_yield();

    should be replaced by

    #ifndef __MSP430__        

            //yield();

            Task_yield();

    #endif        

    Regards,

    Stefan

    Hi Stefan,

    Thanks for the help. There were few more errors after changing the above suggested line. I resolved them and attached the updated library here so if someone comes to this thread, maybe this file could be useful for them.

    I tested this with MSP430FR5969 and SH1106 OLed.
