    I'm planning to power the Audio Player through a USB mobile phone power adapter which can be purchased almost everywhere these days. For that I need a breakout board like this one (alternatively this one). I also...

    The idea behind the large display is that it should be easily read from a distance. The user will mostly be operating the unit from his / her remote control. That looks nice, I'll look into that. But I'm gonna stick...

    I don't think I'll need it if I'm already using the SX1509 for the keys. i'm currently not planning to use keys on the front panel, merely an IR detector.

    The LCD I was planning to use is here. I haven't found a similarly sized I2C or serial version.

    I was planning to use a large 2 x 16 LCD with HD44780 controller in 4-bit configuration (so I'd need 7 I/O's).

    Nice, I may use the SX1509 breakout board from SparkFun.

    I'm planning to add a LCD display and an IR remote control detector. Most likely the player will not have any buttons on the front panel since I don't think I'll have enough I/O pins left on the Teensy 3.1 I'm ...

    The enclosure I'm using is from AliExpress. The enclosure itself is pretty cheap but the shipping hugely expensive. I'm using this DAC board with a Burr-Brown PCM5102 D/A converter and an I2S input.

    I've switched to Teensy 3.1 as the Audio Codecs package didn't work with it. I even posted a question about it on Github. It now compiles without a hitch and I should have it up and running pretty soon. Stay tuned.

    I'm also trying to make a visual representation of what the audio player will look like using Blender. The dimensions are exactly to scale, based on the enclosure and LCD display I purchased from AliExpress.

    Teensy is going to lose out eventually if debug capability isn't provided at some point. RP Pico has debug capability. It runs the debugger one core and the application on the second core. Haven't seen it yet in...

    Teensy would need to go with Rust if it wants to be taken seriously as far as security is concerned. But Rust has a much higher learning curve than C (I'm also dabbling into Rust). Maybe in combination with TockOS?

    I totally misread Paul's answer. But if not a C SDK what then? Arduino would be a mistake IMHO. Teensy is for tinkerers who are fluent in C and comfortable with manipulating registers and such.

    Good to hear. But if not Makefiles, what other options are there? Your own JSON project files?

    You have to ask yourself: "Do I really NEED a Real-Time OS?" It adds a lot more complexity and overhead. Maybe you can fix it using interrupt based tasking? I've seen a lot of RTOS'es lately, some of them even...

    Also purchased a couple Raspberry Pi Pico's, but haven't tried them yet. Still need to solder some of the pinheaders. But from the documentation it looks like programming in straight C, which I prefer. Best thing...
