I'm new to robotics and I'm enjoying the challenge of just wrapping my head around all this.
For my first robot I'm looking at using the axom MCU. But I need to control about 23-25 servos, along with a few sensors. In the specs for the axom it says I can control up to 29 servos. But only 7 on PWM up to 9 with mods.
So my questions are this.
1. What are the mods required to the Axom to get the other 2 PWM outputs?
2. for controlling the other servos I require, Do I have to have use programming delays to create the PWM or can I add an external timer of some kind using a I2c input to get true PWM? If so what timer?
3. How do complex biped robots use all their servos effectively? A controller with more PWM outputs, programming delays, external timer?
Thankyou in advace for your help.
