I have some doubts about the use of the SPI interface of the RPI3 and its connection with the matrix creator hal (everloop and arc_demo mainly)
- Is it possible to enable and use the second SPI connection of the RPI3 (pins: 35,36,38,40) to connect another slave for example?
- Which library in C ++ controls the SPI of the matrix-creator-hal demos?
- Where can I find the complete ucf for the 40 pin RPI-Matrix connector, since only some basic pins (SPI0, UART, I2C) are found?
The RPI3 pins can be viewed interactively here: https://en.pinout.xyz/pinout/spi
Thank you very much
