I have node MCU V0.9 board & SD card shield for arduino uno. On sd card, I have to make a file in FAT32 format to store data. Sd card has four out pins: CS, MISo, MOSI, CLK
- Can I use this library from arduino in node MCU for sd card?
What library?
- What should be the pin conenction between two boards?
The MISO (master in/slave out) and MOSI (master in/slave out) should be pretty obvious. All you need to determine is which pins the not-really-an-Arduino uses for SPI communication.
The CS line can connect to any pin on the not-really-an-Arduino.
The CLK line connects to the 3rd SPI pin on the not-really-an-Arduino.
