# Film Drum Roller | |
A repository containing the embedded code for a DIY film drum roller (to be added later) | |
Collaborators: | |
* Radu Corcodel | |
* Danny Spence | |
To Do: | |
* Capture case when sequence changes RPM but in the same direction | |
* Derive new equation for mapping cosine to byte when the byte doesn't start from 0 or end at 255 | |
* Derive new equations for controlling ramping time based on difference in RPM | |
* Make custom PWM brackets (0-255) doesn't necessarily correspond to (0-n)RPM because of internal friction, magnetic field saturation and moments of inertia | |
* Store and read pre-built programs from EEPROM | |
* We should probably have an E-stop button too (maybe hooking it up as an interrupt) | |
