De1-soc uart spi i2c

[aiedb]

HII I HAVE THE DE1-SOC BOARD , AND I LOGED IN TO THE LINUX CONSOLE ON THE BOARD
on the board i can reach spi i2c tty devices under /sys/class

and my question is lets say i want to write a c program the send data using i2c

under i2c-dev there is i2c-0 and i i2c-1 , how do i know which pin is connected to i2c-0 and which connected to i2c-1 , are the pins accessible by a header on the board i be very glad for hel thanks

is there a table that shows ' where the communication pins (uart,i2c,spi) is connected to the FPGA pins and where are thy connected to the header pins ?

Hi aiedb,

I think you will require to select the correct pinmux in the design to indicate that specific pin which you will like it to function. Those pins for I2C can be found on the Bank 7A on the schematic.
