I have created a simple c-library to read and write to the fram. So I know my PMOD interface to the arty is working correctly. Next step is to write a more complicated hdl to allow the fram to be accessed directly via a memory location rather than with c code. With that in place I will be able to run the rom directly from the FRAM
fram_spi->begin();
uint8_t test = fram_spi->read8(0x0);
printf("\r\nRestarted %d times\r\n",test);
uint8_t test2 = fram_spi->read8(0x1);
printf("\r\nfirst letter 0x%x\r\n",test2);
// Test write ++
fram_spi->writeEnable(true);
fram_spi->write8(0x0, test+1);
fram_spi->writeEnable(false);
fram_spi->writeEnable(true);
fram_spi->write(0x1, (uint8_t *)"FTW!", 5);
fram_spi->writeEnable(false);
printf("\r\ndone\r\n");
