Which are the pins I should use for SPI comunication with arduino DUE? please specify all four wires for SCLK, MOSI, MISO and CS. I´m currently trying to conect an ADXL345 accelerometer to arduino DUE unsuccessfully using
10 for CS,
11 for SDA,
12 SDO and
pins. This work perfectly in my Arduino Duemilanove, but I need the 3 SPI conections (4 10 and 52) capability of Due.
Those signal names are not really SPI names, more a mix of I2C and SPI, are they from the ADXL345?
Anyway on the Due SPI is as follows
SCK - 76
MISO - 74
MOSI - 75
CS/SS - whatever pin you like. There are 2 dedicated slave select pins (D4/87 and D10/77) but I don't know if the SPI library uses them.
The pinout info is here
thanks for answerring, I´ll try those pins.
In the picture is the accel that I´m using, ADXL345, so you can see the names of the conections.
One last thing, shouldn´t been 3 dedicated spi pins D4, D10 and D52?
Yep. Missed that one.
Like I said though I'm not sure if the SPI lib uses them, I would assume not.
