Converting 10bit ADC result to 8 bit

[jmgelba]

Correct me if I'm wrong but if you divide a 10 bit result by 2, you get a 9 bit result. EG 1024/2 = 512. 8 bit max is 256 so you'd have to divide it by 4.

you're correct, this

or dividing by two

was my hands playing catchup with the brain

Why all this manipolation loosing valuable information contained in the 10 bits ADC, when you can store the whole 10 bits in the eeprom.

Write 0,ADC.lowbyte
Write 1,ADC.highbyte

Will store

Read 0, ADC.lowbyte
Read 1,ADC.highbyte

Will retrive your word.

Cheers

It'll also half the number of results that can be stored. Accuracy wasnt an issue, number of results was.
