    FPGA to CortexM3 problems

    Here is the SPI code (most of the SPI section came from fpga4fun.com) module LPCFPGA(input clk, input SCK, input MOSI, input SSEL, output MISO, output reg step, ); // SPI Registers reg [7:0] mem [0:24]; reg [7:0] memCount; reg [7:0] sendmem [0:4]; reg [2:0]...

    FPGA to CortexM3 problems

    I have checked the SPI lines and like I said, when I set it to the static value (123456789) that comes through perfectly. Its when I read a previously sent value, it comes back but not in the correct order ("7B 7B 00 00" instead of "00 00 00 7B") So the number is there its just losing order or...

    FPGA to CortexM3 problems

    I have a FPGA pulse generator design that is connected to a STM32 board with SPI and I am having a strange problem with sending / receiving data. The basic operation is that I send a quantity of pulses to the FPGA and then a frequency to pulse them at. The FPGA then counts them down as it...
