I’m looking to hire somebody for a couple hours of of work helping me integrate a hardware sensor (https://pulsesensor.com/) into the daisy and to help me setup a decent dev environment. Haven’t used my board for nearly a year because development feels so clunky and things are currently a bit over my head. Would really love to feel inspired again and I’m hoping having a functional pet project would do that. If you’ve got some hardware experience and know how to setup a decent tooling chain, please let me know!
Looking at this video here
you could probably just use the sensor as a CV source. You’d want to build a buffering circuit between sensor and pin so you don’t accidentally damage the STM with too much voltage.
The rest of their library is probably just DSP with that signal
Buffer isn’t needed. All that’s needed (for hardware) is power, ground, and an analog input.
The PulseSensor is powered by DC voltage between from 3 to 5.5V.
The PulseSensor output is in the range 0.3V to input voltage.
I would start with using Arduino IDE, install DaisyDuino and the PulseSensor library.
Regarding setting up the dev environment, if you’re going the C++ route, we uploaded a video recently to help with that. Things have gotten a lot easier in the last year. C++ env video
