DIY: STM32F103C8T6 („Blue Pill“) + Oled (TFT-) Display..

okay,
bought some STM32F103C8T6 („Blue Pill“) of about 1,55€ (1,72$) !! at Aliexpress->Link
thought i could use it for my planned own DIY-DAC to display input-source, samplerate, filter-settings, volume etc..

also a 2.6 “ TFT (240X320)->Link (Youtube-Vid is with an 0.96 OLED)

 

 

 

you can program/flash it with a Raspberry Pi->Link, no need for a usb-ttl adapter or ST-Link or something..

so, and with this Arduino IDE u can write some little programms/“sketches“ and write/upload them directly to the chip..
now i must a find a way to read out some information (from maybe a XMOS-USB-Bridge) about the samplerate for example, or maybe which input (USB (I2S), opt, coax) and write it out on a display..
but super no clue at present !! 😉 , i´ll inform you here about some progress..
