Surprisingly enough, this came up recently on the IRC channel for a DBS RX daughterboard. I think they wanted to tune the MAX2118 chip to do GSM frequency hopping. Anyways, the issue is that the SPI bus goes over to the FPGA, but not the I2C bus which connects up to the daughterboard. From wh

Hi all, I'm trying to understand if this is possible in the FPGA. Let's assume we initially tune a card to 2.4G and then every 650us we want to retune it to the prev frequency plus 100MHz, up until 2.5G and then wrap back to 2.4G. That is very easy to accomplish using inband command packe
