buildDeviceInfo()

fl::json autoresearch::flex_io::buildDeviceInfo ( fl::u8 instance )

inline

Build the device-info JSON returned by the flexIoDeviceInfo RPC.

Shape:

{
  "bus": "FLEX_IO",
  "instance": 0,
  "driverName": "I2S_SPI",          // whatever IChannelDriver::getName() returns
  "silicon": "ESP32",
  "idfVersion": "5.5.4",
  "supportedByBuild": true          // false when no BusTraits<FLEX_IO, N> for this silicon
}
