Ada on the ST SensorTile



So my MakeWithAda project is now completed.

Here is a video of it:

The Air32F103

 Bluepills Its no surprise that Bluepills, such as they were, a smoking sub $2 deal would dry up eventually, taken over by clones, some subtle, some overt. With supply issues still plaguing ST parts for hobbyists, what about these cheap Chinese clone parts? Lets dive into the Air32F103. Air32F103 I bought 5 of these $1.90 boards. They look like this: Some notables vs a stock bluepill: 1) Castellated pins with flat underside for use as a module 2) 3 LEDs R/G/B (vs just the G for a bluepill) 3) Clone of ST's peripherals 4) over clockable to 256Mhz (spec is 216Mhz) (original STM32F103CB is 72Mhz) 5) 32K of ram. But, via secret regs, 97K(!) 6) top and bottom debug pads, top for JLINK, bottom, legacy STLINK SWD 7) USB C vs USB mini 8) BOOT as a button vs jumper 9) 2 12bit DACs (STM32F103CB's don't have that) 10) QSPI (hidden support) 11) Undocumented crypto block from MegaHunt (includes: AES/DES/3DES/SHA/SM[1,3,4,7]) Clocking As mentioned 256Mhz is possible. One Q is how do they...

Ada on a $2 eBay 'Bluepill' board (STM32F103C8T6)

For about $2 a 'bluepill' board can be obtained from eBay. Taking its name from the PCB patina this small board is used in the Arduino community. The SoC itself per ST's early docs on it was 64k flash and 20k data, that said, all STM32F103C8's you buy nowadays are 128k flash. The CPU is a Cortex-M3 which can be run at 72Mhz maximum. There is a good website that shows the schematic and pinout of the bluepill: http://wiki.stm32duino.com/index.php?title=Blue_Pill If you are an Arduino programmer, the link above will take you where you want to go. But suppose you wanted to try programming and using the bluepill a different way? Well that is what this blog entry is about. An Ada port was done via AdaCores Ada_Drivers_Library and the Libre GNAT toolchain to the bluepill. This is preliminary work but it is able to generate working code that the author already is using as of yesterday (a garage parking measurement sensor).  The port of the library is derivative, ...
