Hardware

Two STM8L boards can be used with this firmware:

●

The STM8L discovery board. It can be used as a demonstration board.

●

The STM8L evaluation board. It can be used as a development board.

8.2.1

STM8L discovery board

The STM8L Discovery board helps you to discover the STM8L ultra low power features and

to develop and share your applications. It is based on an STM8L152C6T6 and includes an

ST-Link embedded debug tool interface, an LCD, LEDs and push buttons.

The LCD of the discovery board used the most of available GPIO and the available GPIO is

not enough to communicate with the CR95HF devices. This is the reason why the LCD of

STM8L discovery board is deactivated.

The LEDs are the only information source for the user application.

The STM8L discovery board documentation is available on STM website.

8.2.2

STM8L evaluation board

The STM8L1528-EVAL evaluation board is designed as a complete demonstration and

development platform for the STM8 core based STM8L152M8T6 microcontroller with I2C,

two SPI channels, 3 USART channels, 12-bit ADC, two 12-bit DACs, an LCD driver, internal

SRAM, data EEPROM and Flash program memory as well as SWIM debugging support.

The full range of hardware features on the board is provided to help you evaluate all the

MCU peripherals (motor control, USART, microphone, audio DAC, LCD, IR LED, IrDA, SPI

Flash, MicroSD card, temperature sensor, EEPROM… etc.) and develop your own

applications. Extension headers make it possible to easily connect a daughter board or

wrapping board for your specific application.

An ST-LINK V2 is integrated on the board as an embedded in-circuit debugger and

programmer for the STM8 MCU.

The STM8L evaluation documentation is available on STM website.

8.2.3

CR95HF plug board

The PLUG-CR95HF-B is a board which includes a CR95HF device and a matched antenna.

A host configured as a master can communicate with CR95HF through the SPI bus.

The PLUG-CR95HF-B is powered through the Vps pin and no external power supply is

required. It includes a CR95HF contactless transceiver, a 47 x 34 mm 13.56 MHz inductive

etched antenna and its associated tuning components.
