Develop locally using a Matrix Portal and 64x32 RGB LED matrix

Post by trevorlittle »

Hello!

I have a Matrix Portal and 64x32 RGB LED that I've been playing with. Development is slow going because every time I want to test how something looks on the display I have to wait for a reboot. Is there a emulator of some kind to speed up development? Or is there a faster/better way to do this kind of testing?

I would think reboot would be less than a few seconds. Is it taking longer than that?

Using a SEGGER J-Link (jtag programmer) would allow you to change values and single step code. Probably more hassle than it is worth, but invaluable if you are dealing with a lot of bugs.

Thanks, you're right. The startup time is long because I'm connecting to an AP and fetching some JSON. To speed that up for development I guess I can keep the JSON locally and add the networking last.
