The signal generator is still under construction.

Hello.
In previous post I described theory of DDS - now I am going to deal with all connected with construction:
- power,
- communication with PC,
- PCB board,
- etc...

As I wrote in first post, signal generator will be independent device controlled by PC. In last week I created electrical schematic for power and STM32F100. Signal generator will be powered by battery Li-po 3.7V and charged from USB - I will use charger from TI.

Next important issue is communication between PC and SG (signal generator). Communication will be based on modules HMTRP which working on 868MHz. There are modules simply to utilize and enough to my use.

I hope that in next post I will be able to show you picture with results of my work.
