Title: how does a microcontroller acquires the control signals Post by: S_D on March 28, 2013, 07:52:41 AM do the 4 channel rc helicopter transmitter use interrupt driven program for the controls for sampling the analog signal or it samples the analog signal from the controls after a particular intervals of time, periodically, and sends it to transmitter ?

In short, sampling and transmission is done at about 50 times a second with values inter-positioned in the 20ms time period.
