Hi, i'm in trouble with my project.. i need help to find the right connections
i need to use at the same time:
- SPI Display (Gnd, Vcc, Clk, Din, Res, Dc)
- The Audio Board
On the audio board i also have the memory chip that use the pins 6, 7, 12, 14
i also need to use
- the teensy onboard sd card
- other i2c things
- MIDI in/out on 0 and 1 pins (or other pins)
- usb host
- 8 pin for 4 encoders
- 4 pin for encoder buttons
** extra buttons and leds on i2c bus with HT16K33 chip
can I get help on how to connect everything while avoiding conflicts?
thank you
i need to use at the same time:
- SPI Display (Gnd, Vcc, Clk, Din, Res, Dc)
This display, connected to teensy in this way, works: Clk = 13, Din = 11, Res = 8, Dc = 9
i use the u8g2 library, the call for the display is
*the U8G2_SSD1322_NHD_256X64_F_4W_SW_SPI (software) it does not work for me, it's too slow
and HW works only on SPI pin (https://github.com/olikraus/u8g2/issues/479)
as you see, the display initialization use only 11/9 and 8 but if i doesn't use Clk the display doensn't works.

Code:
U8G2_SSD1322_NHD_256X64_F_4W_HW_SPI u8g2(U8G2_R2, /* cs=*/ 11, /* dc=*/ 9, /* reset=*/ 8);

- The Audio Board
The AB use the pin 9, 11, 13, 18, 19, 22, 23
the pin 11,13 are used by the display!!!
