Issues with Sending Data to Microcontroller via SPI Using DE10-Lite Board

Hi Everyone

I am using Intel DE10 lite M50DAF484C7G from this i am trying to communicate with microcontroller just a basic communication sending some random data but its not sending any data so in that i am using Arduino pins for spi pins can i have just a basic code for simple spi master and arduino pins i am using are correct or should i use other pins

Thanks

    Hi,


    We don't provide code support for 3rd party tool but I believe you may grab the code in Arduino website.

    Hi,
    some issues with the code

    - bit_cnt == 8 (else condition) does never happen, need reg [3:0] bit_cnt;

    - data_reg is only loaded once on POR, spi_master sends mosi == 0 constantly after first frame

    - using always @(posedge sclk) is legal but might cause timing issues in a complexer design. Better use single system clock and modify
    clock-enable scheme respectively

    What's the indended SPI mode?

    Regards
    Frank
