Slow week

Not much progress this week. I have decided to go down the route of using hardware PWM modules, with an i2c interface, to control the servos and therefore reduce jitter as much as possible.

The general overview looks similar however, each hardware PWM module can now control 16 servos. I’m waiting for a couple of these PWM modules to come in from overseas, along with some prototyping shields for the Arduino – this will allow the DCC interface module to be directly mounted onto the Arduino making the entire project much simpler and tidier.

More updates next week…
