The ALLBOT spider uses the 9G servo motors to animate its legs. The Arduino implementation uses a built-in servo library that allows assigning servo instance to a pin and then writing desired orientation degrees between 0 and 180. The e310x HAL does not have servo implementation, nor the Embedded HAL have the servo trait. Time to face the hardware at the lowest level! The first thing is to find the datasheet for the 9G servo motor.
