    ADXL103 Calculation: Get Equation for Tilt Angle into MPU

    Dear Notime , I hadn't thought of that! Seriously, The equation for output V I think I can deduce would have the form V = k2 *2500 + k1 *500*sinA for positive angles ; V = k2 *2500 - k1 * 500*sinA for negative angles, But I also note the ADXL202 is 1999, betteer...

    ADXL103 Calculation: Get Equation for Tilt Angle into MPU

    Dear experts, I'm trying to get an equation for tilt angle into a MPU. This is no problem if you can find the equation. The ADXL103 data sheet is indeed mysterious in that it is about a chip that measures acceleration. and yet gives no formula for the relation between...

    How do different variables affect the power needed to ride a bike?

    Dear Gurus First thank you Fred for getting me out of the muddle as to which pounds we are using. That has go me up and running with my assembly code. As to correlation I take it you are asking about what what Jeff Reid wrote in a previous answer. Maybe he had assumed as obvious that the...

    How do different variables affect the power needed to ride a bike?

    Dear Gurus, I'm coding a microprocessor controller for a 0.1hp motor. to assist going up hill on a bike. But the RR equation seems strange I found the equations relating the bike losses, mechanical, rolling resistance , airdrag... with speed and hence horsepower and calories. Here...
