Pirate 3 Posted May 5, 2021 (edited) Hello, I am upgrading my 4 digit LED clock to a 8 digit MAX7219 On the 4 segment, was very simple to set up. SCL -> I2C7_SCL SDA-> I2C7_SDA However, my new board has: CLK DIN CS (It also has DOUT LODA but maybe dont need to use these) However I can not find these pins in the manual. For CLK, I have found CLKOUT, I2S0_SCLK, SPI1_CLK, SPI5_CLK but not sure I found SPI1_CSN0 which maybe is for CS? Can anyone please tell me which pins required for use with Tinkerboard? According to some tutorials, Board Pin Name Remarks RPi Pin RPi Function 1 VCC +5V Power 2 5V0 2 GND Ground 6 GND 3 DIN Data In 19 GPIO 10 (MOSI) 4 CS Chip Select 24 GPIO 8 (SPI CE0) 5 CLK Clock 23 GPIO 11 (SPI CLK) VCC 5V GND GND DIN MOSI CS CE0 CLK SCK Edited May 5, 2021 by Pirate Share this post Link to post Share on other sites
Pirate 3 Posted May 5, 2021 I successfully got it working For anyone else who is wondering, I got it working on SPI5 CS -> SPI5_CSN0 CLK -> SPI5_CLK DIN->SPI5_TXD 1 Share this post Link to post Share on other sites
