Really no code?
Really. For simple interaction with a peripheral to “get to blinky”, no code is needed. For example, with an I2C-controlled digital potentiometer, one only needs to poke one or two values into the pot’s registers to set the device to a specific resistance. Likewise, an A/D converter may just need a few operations for set up, and its output data can be fed directly into Edger’s graphing function.
Though it supports a wide range of functions, Edger is not a one-size-fits-all solution. More sophisticated operations can be supported via user-generated HTML/JavaScript or other code if desired. Support for running user-generated native application code (such as C++) alongside the Edger controller code is also in development.
