Hi everyone,
I’m building a simple air quality monitor using R1BBIT and wanted to share the approach and get feedback on best practices.
📌 Goal
Read data from an SCD41 sensor (CO2, temperature, humidity) and display it on a 320x240 SPI screen in real time.
⚙️ Current Approach
- I2C for SCD41
- SPI display for output
- Periodic sensor reading (~5 seconds interval)
- Updating only changed values on screen (to avoid flickering)
