  • honey the codewitchH honey the codewitch

    When I wrote my GFX library for IoT, I intended it to be cross platform, but due to the specs of most IoT devices being abysmal I haven't had a chance to use anything non-ESP32 since they just don't have RAM, program space or CPU to do anything significant. However, I've been looking at shifting my focus away from the ESP32 to the ARM line of offerings for a number of reasons. I want to take GFX with me, but I wasn't sure it would run on an ARM. I finally fired up GFX on an ARM for the first time today. The only hitch in my getalong was that the STM32 folks did not implement the Arduino framework properly so I had to put a conditional compile into GFX so it will work with the broken ARM arduino layer. That's small potatoes in the big scheme of things. In the end it works. It actually fired up and compiled, and ran which is huge considering the complexity of this codebase, and that this is the first time it has ever been tried on something other than a PC or ESP32. I feel good about today. I'm on fire.

        Your bachelor's degree is in Computer Science or Electronics? How come you are so good at the embedded systems' work?

          I have no degree. I think I got good at doing it because I learned to code back in the 1980s when most PCs were spec'd like the little MCUs I work on today.

            Wow, you're autodidact. I was surprised you knew how to use a logic analyzer. You're really a smart guy!

              Thanks. I learn what I need to know. I have a knack for tinkering.

                You'd be surprised as how many regulars of the Lounge are brilliant people, and autodidacts. That's why I have been visiting this site for 20 years, the concentration of knowledge is amazing (plus I could make illusion so far even if I cannot distinguish an Arduino from a washing machine, so they did not kick me out).

                  This is so true. I am glad I had the chance to live this as well.

                    Same. I think because of it, the challenge of working in a constrained environment is neither overwhelming or off-putting. In fact, I find it enjoyable, maybe because I grew up with it. Something about it is almost comforting. Give me an ESP32's 300kB of usable RAM any day and I'll feel spoiled. :). I remember when I had to work with 64kB so no big.

                      4k (ROM) should be enough for everyone[^] :-D

                        That's impressive. Too bad I don't have a 1080 lcd display for an IoT MCU, or one that could push that many pixels. I doubt that thing *runs* in 4kB though. I'm sure it uses runtime decompression to get those textures, or to generate the computation tables needed to render those textures, and it would have to cache some of that to get any kind of frame rate. But yeah, impressive.

                          Of course, it definitively uses decompression, but still impressive. Plus the music is also rendered. There are is so much maths and cleverness in this...
