STM8 development tools

Typically, the following tools are needed to get started:

●

STVD, IAR workbench, or RIDE for integrated development environment

●

STM8 C compiler (from Cosmic, Raisonance, or IAR)

●

ST toolset from STMicroelectronics

●

Firmware libraries from STMicroelectronics (STM8TL5x_StdPeriph_Lib and

STM8TL5x_STMTouch_Lib for STM8TL5x)

●

STM8TL53 Touch keypad Evaluation board or STMT-BOX™ (a) Evaluation kit from

STMicroelectronics.

●

The debug interface ST-LINK is included in STMT-BOX™ Display board

●

If you do not use STMT-BOX™ Display board, you may need the hardware debug

interface ST-Link from STMicroelectronics or "Rlink" from Raisonance.

●

STMStudio is a graphical user interface that allows sampling and viewing user

variables in real time using any hardware debugging tool while the application is

running.

9.1

Single wire interface module (SWIM)

9.1.1

SWIM overview

In-circuit debugging mode or in-circuit programming mode are managed through a single

wire hardware interface based on an open-drain line, featuring ultra fast memory

programming. Coupled with an in-circuit debugging module, the SWIM also offers a non-

intrusive read/write to RAM and peripherals. This makes the in-circuit debugger extremely

powerful and close in performance to a full-featured emulator.

The SWIM pin can be used as a standard I/O (with 8 mA capability) which has some

restrictions if the user wants to use it for debugging. The most secure way to use it is to

provide a strap option on the PCB. Please refer to the STM8 SWIM communication protocol

and debug module user manual (UM0470) for more SWIM protocol details.
