Laboratory Exercises

Attendance is mandatory. Laboratory exercise mainly servers to acquire practical experience of the programming skills. The results of partial tasks are available in the upload system: https://cw.felk.cvut.cz/upload/.

The aim of the exercise is to apply the constructs explained in lectures at an example, which is derived from daily-used applications. The C language is used in an embedded system for software developmnet for applications that require fast access to the hardware (controller, data collection). In the exercises, students shall create a system coposed from embedded device and a PC which is capable to sucessfuly exchnage data via serial interface. The objective is to implement a software platform for NUCLEO board and for Linux (text mode). Both applications will communicate through a serial interface which is integral part of the STlink 2.1 debug interface. The NUCLEO implementation will use a state machine to maintain the communication and the PC based app (Linux OS) will use multithreaded approach. The aim of the exercise is to implement a system currently used to connect external hardware (various bus analyzers, cash registers in stores) with a graphical terminal (PC: Windows, Linux, Tablet: Android, MAC OS).

The designed device will allow to:

• Control the state of the LED light
• Read the state of the USER button
• Read the state of the analogue joystick
• Draw on the display - basic commands - set position, line
• Read the state of the touchpad
