Infrared (IR) interface

The high density value line STM8L05xxx devices contain an infrared interface which can be

used with an IR LED for remote control functions. Two timer output compare channels are

used to generate the infrared remote control signals.

Development support

Development tools

Development tools for the STM8 microcontrollers include:

●

The STice emulation system offering tracing and code profiling

●

The STVD high-level language debugger including C compiler, assembler and

integrated development environment

●

The STVP Flash programming software

The STM8 also comes with starter kits, evaluation boards and low-cost in-circuit

debugging/programming tools.

Single wire data interface (SWIM) and debug module

The debug module with its single wire data interface (SWIM) permits non-intrusive real-time

in-circuit debugging and fast memory programming.

The Single wire interface is used for direct access to the debugging module and memory

programming. The interface can be activated in all device operation modes.

The non-intrusive debugging module features a performance close to a full-featured

emulator. Beside memory and peripherals, CPU operation can also be monitored in real-

time by means of shadow registers.

Bootloader

A bootloader is available to reprogram the Flash memory using the USART1, USART2,

USART3 (USARTs in asynchronous mode), SPI1 or SPI2 interfaces. The reference

document for the bootloader is UM0560: STM8 bootloader user manual.

The bootloader is used to download application software into the device memories,

including RAM, program and data memory, using standard serial interfaces. It is a

complementary solution to programming via the SWIM debugging interface.
