I created a 7 segment display demo It has 7 lines and a decimal point. You pass it binary strings to display. I created a map for letters and numbers plus space. You can add as many characters as you wish, I went with 4. It starts and says HI, then lets you input a string. It only displays the first 4 characters.
My plan was a digital alarm clock. This is the starting point. I could see this used for many things. You need to wait for each digit to finish displaying before moving on to the next one. Set updatecount to 0, broadcast, wait until updatecount = 8. Broadcast and wait is not working.
