iSV57 servo communication
The picture below shows the voltage over time of the servos Rx (channel 1) and Tx (channel 2) ports, probed while the ESP was connected
The osciloscopes settings are:
5V/div
5ms/div
One can see, that the channels have low levels of -5V and high levelsd of +5V. The latency between the end of a hosts Tx burst (channel 1) and the start of the clients burst (channel 2) was up to 3.5ms.
