Following your discussion, I noticed that the MAX6955 is available in the Proteus library. I decided to run a quick test and got the results shown in the attachment.
I know Proteus isn't a perfect replacement for real hardware, but as a hobbyist, I always use it to test my code first before spending money on components.
Nice work!
I will soon order two pieces of MAX6954, from which I will make two development boards - one for Martin and one for me.
At the same time, Martin will work on making the MAX6955 a component in Flowcode, and afterward, the MAX6954.
I will have to solder many wires, but once I have a prototype ready (in 1-2 weeks at most), I will post some pictures here on the forum.
