IDE
●
For bare-metal programming
●
Lightweight – Arduino IDE
●
Heavy duty – STM Cube
KYPO PC Environment setup

●
Data should be stored in cloud
●
Today’s goal: configuration and test of the IDE
●
Application: just blinking the LED
Private laptops
●
Download and install Arduino IDE:
●
https://www.arduino.cc/en/software
●
Available for Windows, Linux, and MAC
●
Currently, we use release 1.8.19
●
Latest available release 2.3.3

Basic example
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on
delay(1000); // wait for 1000 ms
digitalWrite(LED_BUILTIN, LOW); // turn the LED off
delay(1000); // wait for 1000 ms
}
Basic example
●
Task: change the delay time in assymetric way, e.g.,
2000 ms HIGH state, 100 ms LOW state
●
Observe the result

Explanation?
Basic example
STM CUBE IDE
●
Offered by STMicroelectronic
●
Covers all STM32 MCUs
●
C / C++
●
Based on Eclipse → similarity with Simplicity Studio,
MCUxresso, Code Composer Studio, ...
●
Used also for ST-Link SW upgrade
●
Can help to install ST-Link drivers
●
MCU specific libraries downloaded on per project basis
STM Cube on KYPO PCs
