Quick start

The STM8A-DISCOVERY is a low-cost and easy-to-use development kit to quickly evaluate

and start a development with STM8AF and STM8AL microcontrollers family devices.

STM8AF devices offer high performance and full automotive network connectivity with high

speed CAN and LIN master/slave modes communications. STM8AL devices offer high

performance with ultra-low power management. Both comply with automotive qualification

and conform to AEC-Q100 rev G.

2.1

Getting started

Connect CN3 and CN4 on the STM8AF board to CN3 and CN4 on the STM8AL board.

Connect both type A connectors of the USB cable to a PC.

Then connect the mini-B connector of the USB cable to the STM8AF board.

All LEDs blink once on the STM8AF board and twice on the STM8AL board, then the

LIN communication between both boards starts.

Turn the RV1 trimmer on the STM8AF board to adjust the value from 0 to 100 on the

STM8AL board LCD through the LIN bus.

Push button USER1 on the STM8AF board to sequentially display the LCD bars on the

STM8AL board through the LIN bus. Push button USER2 on the STM8AF board to

sequentially switch them off one by one.

Push button USER1 on the STM8AL board to sequentially switch on green LEDs LD4,

LD5, LD6 and LD7 on the STM8AF board through the LIN bus. Push button USER2 on

the STM8AL board to sequentially switch them off one by one.

To perform or modify the Discover project related to this demo, visit www.st.com/stm8a-

discovery.

You can discover the STM8AF and STM8AL features, download and execute programs

proposed in the list of projects.

10. You can then develop your own application using the available examples.
