Re: In need of accessing more than 255 bits in a byte/word array.

Thanks for the link sayzer! I have read it before a long time ago and it was very helpful at the time. As it turns out, the method stated by melanie does not coincide with what the manual states. I...

Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

I already wrote code with if-then-else, and it works fine, just wanted to make it more nice and tidy.

regarding port mapping, ports are 8 bit wide, but nixies are 10 bit, so that way won't work...

Re: In need of accessing more than 255 bits in a byte/word array.

another way is to stick with a byte array any use an asm call to the L?CALL ARRAYBIT ,macro after setting fsr to appropriate offset
and calculated byte index for testing bit set or not,. bit...

Re: In need of accessing more than 255 bits in a byte/word array.

Thanks Richard. I already use a similar approach to set and clear the bits within my array but it's not as elegant as yours.

BrdCountLp0 = Address/16 ; I divide by 16 to select the...

Re: In need of accessing more than 255 bits in a byte/word array.

value
bit = array[abc/8]&(1<<(abc//8))
to set
array[abc/8]= array[abc/8] |(1<<(abc//8))
to clear
array[abc/8]= array[abc/8] & ~(1<<(abc//8))

In need of accessing more than 255 bits in a byte/word array.

Hello all.

I'm sure this question has been asked a million times before but has anyone found a way to access more than 255 bits in a byte/word array with a variable bit index?

Any and all...

Re: Hitachi vs Sitronix LCD

Thanks, Dave.

Working through the list I found no connection to R/W - on the Hitachi this seems not to be required. Yours is a good reminder that you may get away with poor programming practices...
