For what? With these things I just add them either inline or on the PCB that I attach the teensy to

The 3.1/3.2 are the exact same as far as wiring [and pretty much everything else] goes and has 3.3v CS, D/C, SDI, SCK which is why it says to USE a 3.1 (or higher) and not a 2.0 which was 5v

Well that makes things a tad more simple. So only the signal (cs) needs to be unique? I have done a TON of work a while back with Addressable LEDS + WIFI + SD + NMEA GPS and I was so out of pins, but now it makes a lot more sense. It's kind of like the I2C bus on my Pixhawk and APM flight...

Thanks for the reply. You can share pins? I already have the LCD on pins 11/12/13. If this is the case can't I just run a bridge between the SD_ and LCD_ MISO/MOSI/SCK?

What are the default pins for the SDCard on the teensy3.1? LCD Teensy3.1 SD_CS ?? SD_MOSI ?? SD_MISO ?? SD_SCK ?? F_CS ??

yike I followed these directions: https://www.pjrc.com/store/display_ili9341.html ILI9341 Pin Teensy 3.1 Standard Teensy 3.1 Audio Board Notes VCC VIN VIN Power: 3.6 to 5.5 volts GND GND GND CS 10 21 Alternate Pins: 9, 15, 20, 21 RESET +3.3V +3.3V D/C 9 20 Alternate Pins: 10, 15, 20, 21 SDI...

Yup no-name chinese vendor lol. And I was able to get the graphics tests working using the ILI9341_t3 libraries with 0 modifications to the board. Well as far as the LCD goes. I'm still not sure if I should be able to use the SDCard over the same pins as the LCD or if I have to use the pins on...

I have a board I just got which is different than the ones shown here. Am I correct that doing the following will allow me to connect this directly to a teensy3.1 without needing a line converter AND be able to use the other pins to use the SDCard reader as well? Reason I ask is because it...

I just wanted to say thanks for all the work that has gone into Teensyduino because without it I would be so totally lost with my very limited arduino knowledge and even less the Teensy. Props! Now my question. I'm using this code #define HWSERIAL Serial1 #define DATA_PIN 2 const int...
