How to connect W25Q128JVSIQ (Flash memory) to Wireless Tracker

#1

Hello,

I’m trying to connect 128Mbit Flash memory (W25Q128JVSIQ ) to Wireless Tracker.

I’m planning to connect:
TFT_SDIN (MOSI) to DI
TFT_SCLK (SCK) to CLK
some GPIO to #CS

But which pin can I use for DO / SPI MISO? Can I use GPIO15 / GPIO16 or maybe GPIO17 / GPIO18?

Whatis the best way to add Flash memory?

Thankful for any tips!

Hello! All GPIO pins can be used for SPI linking, as defined in the code.
But if you use those pins that are being used, it may cause you to be unable to use the corresponding functions, such as when you use TFTSDIN, it may cause you to be unable to use the display screen.
