Hello all,
I'm working on a new project, an electronic sensor and datalogging system for a high power rocket. As part of it I need to interface an accelerometer with an analog 0-5v signal to an adc on my pic mcu that accepts 0-3v3 signals. To complicate things, I only want to the negative g data, so I only need the 0-2.5v signal and want anything above that clamped and want the 0-2.5v signal expanded so that I can use the full resolution on the adc in my microcontroller. This is a lot of precison analog stuff..... I've never done this before. Any solutions would be very helpful to me.
Thank!
