soft programmation ampli AD8555

Je suis désolé. Je ne comprends pas.

Hi! I translate the author is looking for a source of any microcontroller/µP software routine (device driver) in C or assembly language of an application that uses the chip p/n AD8555 [Digitally Programmable Sensor Signal Zero-Drift Amplifier] from Analog Devices (see :

So anybody that have designed someth>

Hello Programming the AD8555 is hardware dependant. You must send 3 x 38 bits binary serial words with pulses:

- between 50ns and 10 us for loading 0

- bigger as 50 us for loading 1 with an interval between pulse bigger than 10 us. These pulses can be done by hard or soft. Analog Devices give a schematic for hard. For soft example with a Parallax STAMP II this program:

Output 0 Deb: pulsout 0,2 Pulsout 0,30 Goto deb

Give a 4 us pulse and 214us after a 60 us pulse.

Software loop or use of timer (microcontroler or PC) in ASM, C, Basic... can give best results

See you later...perhaps at Nancy!
