I this illustration we will going to install and configure the newly Micro Mini Pro Microcontroller Board. This board can run as Leonardo bard or using boot load SF32U4 boards. Below are the steps how to install and configure using SF32U4 on the Arduino IDE. The first step is you need to locate the Arduino sketchbook directory located at the Documents folder, you can verify by opening the Arduino IDE > Preference > see the steps below.
- Micro Mini Pro Board MCU
- Download SF32U4 Boot Load and Driver
After you unzipped the folder named SF32U4 you need to create a hardware folder inside of the Arduino folder see below illustration for the structure of the folder.
Wiring the Reset Button
Boot Loading / Flashing Firmware
Demo Sketch Code
int RXLED = 17; // The RX LED has a defined Arduino pin
// The TX LED was not so lucky, we'll need to use pre-defined
// macros (TXLED1, TXLED0) to control that.
pinMode(RXLED, OUTPUT); // Set RX LED as an output
// TX LED is set as an output behind the scenes
Serial.begin(9600); //This pipes to the serial monitor
Serial1.begin(9600); //This is the UART, pipes to sensors attached to board
Serial.println("HELLO! 14CORE"); // Print "Hello World" to the Serial Monitor
Serial1.println("14CORE"); // Print "Hello!" over hardware UART
digitalWrite(RXLED, HIGH); // set the LED on
TXLED1; //TX LED is not tied to a normally controlled pin
delay(1000); // wait for a second
digitalWrite(RXLED, LOW); // set the LED off
