Shutter
Shutter is an open source STM32 PCB design by eddyem: a 2-layer, 61 × 49.5 mm board with 40 components (29 distinct parts). It is built around the BME280, STM32F303CBT6, ISO1050DUB. Filed under sensors.
Code samples and ready projects based on bare-metal STM32
Works with bi-stable shutter. You can find the device in /dev/shutterX (symlink to /dev/ttyUSBX).
After powered on, the device will try to close shutter (during one second).
The CCD (or manual) controlled input allows to open/close shutter by changing its level (depending on ccdactive parameter). If current configuration can't open or close the shutter immediately, it will be opened/closed as soon as possible, while the input holds its level.
