Hi All,
Great Forum...
I have obtained an old LED scoreboard that is based on an 5450/5451 7 SEG driver, which I want to control via a picaxe 8, or 18x.
I have created a couple of the more simpler projects using the PicAxe 8, so are familiar with PicAxe, but by no means an expert. The issue I am having is that the 5451 requires synchronous serial data, based on a seperate clock cycle. I notice the picaxe has a serial output, but this appears to be an asynchronous using stop and start bits.
I need to send a clock out from one pin, while at the same time send 36 serial bits in sync with the clock. Alternative supply an external clock, and sync the output stream to this clock. This prcoedure is required for each of the 7 segment changes.
In order to do this, I need to know if there are any commands that can synchronise the two. Any assistance would be great...
Thanks,
Brian
