A "Drogue IoT" Thing

An example device, implemented with Drogue IoT in Rust.

NOTE: This is mostly my personal example project and playground.

Pre-requisites

• STM32F723E-DISCOVERY board
  • ESP-01 (plugged in the Wi-Fi slot)
• STM32F411 Nucleo 64
  • ESP-01 wired up to UART1
  • BME680 sensor connected to I2C1

Build

For STM32F411:

env CC=/usr/bin/clang cargo embed --release --features stm32f411

For STM32F723:

env CC=/usr/bin/clang cargo embed --release --features stm32f723

Wi-Fi credentials

You can put your Wi-Fi credentials into the following files:

• src/wifi.ssid.txt
• src/wifi.password.txt

When you enable the feature custom_wifi, it will use the information from these files.

Display

The example allows to plug in a display as well. As there is a huge varietey of models and drivers, it is necessary to adapt the code to yours. That is why this is an additional feature display, which needs to be activated explicitly.

When enabled, by default, it expects an "ssd1351" display having a size of 128x128, with RGB565 color format. As display support is implemented using embedded-graphics, it should be relatively simple to implement a different display type.
