I need to find look for some test code for the Spartan 3 board and get the tools setup (I have a shortage of Windoze machines ...) Once I get the board going, I need to remove the 3.3 volt oscillator from the main board and get the same code running with the 1.8 volt oscillator. Then the real fun begins :)
I've got some simple stuff laying around if you want to try. Doesn't need anything except the Spartan 3E starter kit.
The photo is to give people an idea of where we are headed. Hopefully, the board Chris (and others) come up with fewer components than the dev board.
Yeah - that board has a lot more stuff on it than is needed for radio applications (and not enough for radio applications - no fast ADC/DACs).
Fundamental requirements for a radio board: - FPGA - Power supplies (switchers or linear regulators for multiple voltages) - ADC/DAC (any decisions on these yet?) - Frequency source(s) - Control interfaces for radio (SPI/I2C) - FPGA Configuration stuff (Flash memory or Beagle interface) - JTAG Download/debug interface. Should be fairly compact... Eric
