Now with Sweep and Scan Modes
And more RF output with optional Post Amp board!
Now Controls AD9912 Boards!
And AD995x Boards Too!
Here is a controller that works with the new Silicon Laboratories Si570 programmable XO chip, as well as the Analog Device DDS chips used in the popular AMQRP cards. And now also works with the WB6DHW AD9912 and AD995x boards. Plug the WA6UFQ Si570 oscillator card, your AMQRP DDS-30, or DDS-60 card, or an interface cable to a WB6DHW board into the universal controller board, select your card or board from the controller's menu, and then select the Si570's start frequency, or the DDS chip's master clock frequency.
Then from the controller's menu, set start and stop frequencies, and other features such as a frequency offset, or an output multiplier. The configuration is saved in EEPROM, and the controller is now ready to go.
Universal Controller with DDS-30 Card Installed (socket for Si570 card is on left)
This is a stand-alone controller; no computer is required. Communication with the Si570 card uses an I2C interface and code developed by John K5JHF for a Freescale micro controller.I have ported it over to the Microchip PIC24HJ high performance micro controller.
