How it works

This project implements a settings recommender for photography. The ISO, shutter speed and focal ratio values are inputed using a rotational encoder and a four-digit seven-segment display. After inputing the values, an external luxmeter is read via SPI interface and all of the values are used to retrieve the recommended setting from a LUT in an SPI Flash. The recommended value is displayed on the four-digit seven-segment display.

How to test

This project uses a user interface consisting of a rotational encoder and four-digit seven-segment display. After reset or power-up, first the ISO value is selected by rotating the encoder. The current value is displayed on the four-digit seven-segment display and it is confirmed by a short press on the rotational encoder. Next, the shutter speed is selected by rotating and confirmed by a short press of the encoder. Finally, the focal ratio is selected by rotating the encoder and it is confirmed by a medium press of the encoder. After reading the luxmeter and the flash-based LUT, the recommended settings value is shown on the four-digit seven-segment display.

External hardware

External hardware comprises of a rotational encoder, a four-digit seven-segment display, SPI luxmeter (e.g. Pmod ALS) and SPI flash (e.g. MX25L3233FMI-08G).
