Description

MicroXplorer is a graphical tool enabling users to
configure the pinout of an ST MCU very easily by
selecting the peripherals needed for the
application.

In a first step, MicroXplorer helps find the MCUs
in the ST portfolio that feature the peripherals
required. In a second step, by selecting the
operating mode of each peripheral, MicroXplorer
assigns the pins needed for the peripheral in that
operating mode.

MicroXplorer

MCU graphical configuration tool

MicroXplorer provides two viewing modes for
performing the microcontroller configuration: the
Peripherals Panel for selecting the operating
mode of each peripheral and Chip View for
advanced users to force the mapping of a function
of a peripheral to one physical pin.

Table 1. Device summary

Order code Reference

As ST MCUs allow the same pin to be used for

MICROXPLORER MicroXplorer software

different peripherals and functions (GPIO, USART
TX, ADC input channel for example),
MicroXplorer searches for and finds the pinout
that allows using all the peripherals selected by
the user, if that configuration exists.

In addition, at any time users can freeze the pin
assignment of peripherals that have already been
configured while the user continues selecting
peripherals and allocating other pins. The pins
which have been frozen keep their assigned
positions and will not be moved again by
MicroXplorer.
