Honored Contributormax Clock rate at GPIO? (DE2 Board)
Hello, can someone tell me, what the max rate of the GPIO pins is? I have mapped a SPI Interface on the GPIO Pins. But when I select a to high Baud rate, the other side seems to not get all bits...

According the I/O standard used you can calculate maximum delays and clock rate for every FPGA's pin. http://www.altera.com/literature/hb/cyc2/cyc2_cii51005.pdf
