I’m working on a project of recreating this:
But on sort of a larger scale, I am wondering if it’s possible to use a single Teensy 3.6 to recreate something of a similar nature as this.
64 Buttons
8 Encoders with push buttons and touch sense
8 Motorized Faders with touch sense
8 128x64 OLEDs
I plan on using a separate ic to interpret all the touch sense so as to not tie up the Teensy with those. My main concern is the Ethernet side of things since most of the time the entire frame buffer is sent for each OLED (1024 bytes each) when they are updated and I fear that the w5500 spi based modules aren’t going to be able to transfer fast enough to the Teensy. Based on my testing so far, the OLEDs can be updated several times a second and it seems that the Teensy can only keep the buffers of the w5500 from filling up if the sockets are above 8k of memory. I’d like to point out that the buffers on the device I’m trying to recreate are 64k for the Ethernet and using an older 240 MHz NXP Processor with built in Ethernet, which is not out of spec per say with an overclocked Teensy 3.6 with built in Ethernet. However, currently the support for the Teensy’s builtin Ethernet is lacking so I would be stuck with the w5500 on that front.
