hi
I thinking of using lpcxpresso 1768 dev board for my project. Lpcxpreso 1768 board is arm-cortexm3 based board with high embedded computing power. And its a low powered device (3.6volts). the datasheet mentions the adc has input range between VREFN to VREFP and max vdda of 3.6 volts .I am in a lil doubtful if i can interface the 5volts 3-axis analog accelerometer to it becuz it is powered at 3.6volts. Kindly clarify me if the controller has adc range 0-5 volt, so that i can directly connect analog o/p to adc pin or Do i have to convert analog sensor values from 5v to 3.6 v by some additional hardware and then feed the data to the adc pins?.Here the schematics of the board
Thank you....
