#182626 - show sourcecode and BTW... Responding to: ???'s previous message |
...use some special flag - while P1.3=High (E signal to LCD) , do not enable keyboard scanning. After P1.3 goes low - enable keyboard scanning.
For interrupt( pin irq) and timer interrupt You should use different banks R0-R7 , or preserve registers , used in particular interrupt. Dont forget to initialize stack pointer to deep enough value. regards |
