Understanding the simple use of GPIO
Making an LED blink involves connecting it to a signal that alternately switches ON and OFF. General purpose input/output (GPIO) is the name of a microcontroller peripheral that provides functionality to source many signals at once (that is, in parallel). GPIO peripherals are designed to be very flexible, so configuring them can be rather confusing but using the RTE manager makes this process much simpler. We will modify our helloBlinky_c1v0 recipe to simultaneously make all the LEDs blink rather than just one. Each LED on the evaluation board is connected to a pin on the microcontroller, so to illuminate an LED the microcontroller needs to provide a voltage and current similar to the that of a torch battery. ...
