#19095 - RE: port 0 and external memory use |
Hi,
Oh dear after a night away I think I've figured out a problem with what I wrote yesterday... > Then any external write to memory will > apply the required _data_ to the latch of > the DAC. I take it the _data_ won't be latched - it will be the _address_... %-) So in order to write data into the DAC I have to use the data as an address access?? So something of the order: WORD16 dac_var_12bit; . . P1 &= 0xf1; // clear P1.1, P1.2, P1.3 P1 |= 0x06; // set P1.1, P1.2 *(WRITE_LOW_NIBBLE | (dac_var_12bit&0x000f)) = 0; // use data as an address on DAC latch etc??? P1 &= 0xf1; // reset P1.1, P1.2, P1.3 . Help anyone??? Does this sound more like it? Kev |
