    Hi Every body

    How can I calculate the value for the buffers TH0 and TL0 in order to have interrupt every 1ms.

    Thank you very much

    Timer0_count = 0 - (osc/(12*timer0_period)) - 17

    so if your osc freq = 36MHz, then Timer0_count = 0xf459,

    if, osc freq = 40MHz, then Timer0_count = 0xf30c

    Load the high byte of timer0_count to TH0, and the low byte to TL0.
