Week 2: GPIO, SPI, and LCD

After prototyping the ECG front end board we were focusing on configuring a GPIO pin to accept an analog input. After proper research on configuration parameters and experimentation of how to properly access the desired registers, we successfully configured a GPIO pin to take an analog input and read the analog value.

Our next step was to integrate the GPIO analog input configuration and our ADC monitoring program so that we can read our ECG front end input. We were successful at this integration and started to move onto using writing data to the LCD. We were able to configure sending simple data via SPI and are now focusing on how to properly configure the LCD.

We have a good lead onto how to use the 2.2 Adafruit LCD and write more complex data for display and plan to properly display our data to the LCD.

After properly implementing the LCD we plan to look into writing data to a SD card.
