This blog as a making memorandum on an amateur HAM radio Homebrew. Parts supply was also becoming difficult gradually recently. I should be very much obliged if you can do much person's communication.
Homebrewer Mr. Veselin Georgiev (LZ2WSG) of Bulgarian residence. He made my mono-band DDS VFO(Ver3.0) on STM32-arduino,
I didn't know anything as STM32-arduino well, but when it'll be checked, it's quite attractive MPU.
It's equipped with STMicro ARM(ARM32Cortex-M3) and it is arduino-nano interchange by a high-performance board equipped with operation clock 72Mhz, 64Kb flash memory and 20KbSRAM. The development environment is also possible in Arduino IDE1.6.5, and a sketch is also just as it is and they seem to move. It's the performance near arduino duo.
When it's the program of which you request the speed, it's a recommended board.
When it's China, it's possible to buy it for 1.5 dollars. I'm also happy that can get it very inexpensively.
Their basis is OPEN. A wonderful way of thinking which will elucidate all information and share by everyone. Everyone shares information and enjoys through a radio. I think really so. It would like to feel sympathy with this way of thinking as well as be oneself so, too.
