I’m in development of my first product in market. I’m looking for an efficient way to display Ads and device’s interactive graphics in interoperable way.
The device measures Human weight/height on coin insert, displays the results to the display. which is currently ‘7 segments display’.
My application is running on ESP32,
However, I’m investigating how can I add display to the device running adds, which could be interrupted from the application MCU to display interactive graphics/texts (weight / height).
The MCU could send message/command through I2C/SPI/UART to RPI.
RPI can read this message.
But I don’t know how to complete the cycle with display/Screenly.
Let’s summarize it by a sequence :
- Display is displaying ads.
- Human measures weight/height.
- A command to display weight/height that is being read by RPI.
- RPI decides to gently shut off ads, And display some graphics that’s related to the data/command came from MCU.
- RPI returns playing Ads.
And All of this need to be done locally, with no requirement of Internet access to accomplish this.
