0110 – Timing is everything

Before I get much further with the video module, I need to properly flesh out the heartbeat of the system: the timing circuit. As mentioned previously, the /// uses a 14.318MHz clock. The reason for such a high  frequency is that (apart from other components in the system) the video module needs a 7MHz and… Continue reading 0110 – Timing is everything
