Created an issue in makers-for-life/makair-control-ui that received 2 comments
Move all the plotters-conrod library f64 internal types to i32, as to speed up highly-repeated numeric calculations on the RPi
2 graphs at 30 FPS currently consume up to 30% CPU. I suspect that the ARM CPU is quite slow at dealing w/ f64 operations (comparisons, additions, …

- Investigate on partial re-rendering of the UI with Conrod
- Move graph saturation detector to a sliding register of highest + lowest pressure & flow values in the chip module (~0.5% CPU load at 30 FPS)
- Reduce telemetry widgets rendering time (10% CPU load at 30 FPS)
- Compensate for telemetry serial jitter, so that the graph runs at a full 30 FPS (probably due to interrupts at the MCU level)
- The ventilation "heartbeat" animated indicator should adjust its data source based on ventilation mode (pressure or flow)
- Settings for all new ventilation modes
- Firmware and Control UI OTA updates
- Implement new telemetry fields
- Auto close a settings modal by clicking on its black-transparent background
- Minimize graph rendering CPU usage (once moved to ConrodBackend)
- Move graph BitMapBackend to ConrodBackend (need to build it)
- Mix up graph image with the top header image in a single texture (cuts CPU usage by half)
- Add new alarms (added in firmware for new ventilation modes)
- Send an heartbeat telemetry message to the firmware every second (RPi freeze watchdog)
- Ability to snooze alarms and view current snooze status
- Unsupported telemetry protocol version check and error if protocol is incompatible
- Improve error screen (large warning icon and the error text below)
- Re-use the GPU 2D texture at every draw pass, and avoid re-uploading all pixels for rendering
- Optimize the graph rendering algorithm (currently consumes most draw loop CPU)
- Build a minimal Linux image for the Control UI runtime
