Developing DC2N5 for the STM32F100 Discovery too

Today after work I decided to get going with the STM32 Discovery board that I had bought a while back but never used. It’s a cheap board but it’s not quite friendly when it comes to inserting it into a breadboard.
After making the initial connections, I was able to start its bootloader and communicate through its USART1 serial port, which connects to my PC via a TTL->USB bridge (FTDI style).

Here’s the output from the stm32flash utility:

stm32flash.exe -b 115200 COM6
stm32flash 0.4

Interface serial_w32: 115200 8E1
Version      : 0x22
Option 1     : 0x00
Option 2     : 0x00
Device ID    : 0x0420 (Medium-density VL)
- RAM        : 8KiB  (512b reserved by bootloader)
- Flash      : 128KiB (sector size: 4x1024)
- Option RAM : 16b
- System RAM : 2KiB

As you can see it’s not as equipped as the primary MCU I am using for developing DC2N5, but it’s something worth exploring so I am finishing the last bits of porting my framework to the STM32F100 family of MCUs 🙂
