UM0817 Quick start

Doc ID 16361 Rev 2 3/17

1 Quick start

It is very simple to get started using the STM8S-DISCOVERY, just follow these four steps:

1. Connect the STM8S-DISCOVERY to a PC with a USB cable.

2. Press the TS1 button, and observe LED LD1 blinking.

3. Press the TS1 button to change blinking speed.

4. Visit www.st.com/stm8s-discovery and follow the tutorial, then discover other applications.

The STM8S-DISCOVERY helps you develop and share your own application. You can discover more of the STM8S features by downloading and executing the proposed programs in the project list.

Note: The software code corresponding to this application is available under the name Discover in the project list of the STM8S-Discovery web page.

Hardware and layout UM0817

4/17 Doc ID 16361 Rev 2

2 Hardware and layout

The STM8S-DISCOVERY is designed around the STM8S105C6T6 microcontroller in an LQFP48 package. It has two distinct sections that may be separated, the STM8S105C6T6 module and the ST-LINK module.

Figure 2 illustrates the connections between the STM8S105C6T6 and its peripherals (ST-LINK, touch-sensing button, LED and connectors).

Figure 3 helps you to locate these features on the STM8S-DISCOVERY board, as well as the potential point of separation (for more details refer to Section 2.2.2: Using the ST-LINK on other STM8S applications).

2.2 ST-LINK The ST-LINK provides a USB interface for programming and debugging using a single wire interface module (SWIM). The ST-LINK module of the STM8S-DISCOVERY also supplies 5 V and 3.3 V to the STM8S105C6T6 module.

2.2.1 Using the ST-LINK

Figure 6. Typical configuration

Note: The driver for ST-LINK is installed automatically when the USB is connected.

For information about debugging and programming features refer to ST-LINK UM0627, UM0036 STVD and RN0011 STVP. For information about SWIM refer to UM0470.

2.2.2 Using the ST-LINK on other STM8S applications

You can connect your ST-LINK to other STM8S applications in 2 ways.

● By removing the solder bridges: This way uses the ST-LINK without breaking the PCB. Unsolder the two solder bridges SB1 and SB2 under the SWIM connector. See Figure 7. You can re-solder the two bridges at a later date thus keeping the STM8S-DISCOVERY usable.

● By removing it from your board: This way constitutes a good alternative to programming the STM8S devices in other applications. See Figure 8.

Note: This ST-LINK only supports the STM8S family. Do not use it with other STM8 families.

Figure 7. ST-LINK without breaking the PCB

Hardware requirements:- USB cable type A to B- Computer with Windows 2000, XP or Vista OS

Remove SB1 and SB2 solder bridges


Doc ID 16361 Rev 2 9/17

Figure 8. Separated ST-LINK module

Warning: By removing this module you will lose power supply on the STM8S105C6T6 evaluation board. In consequence, you will not be able to program and use the STM8S105C6T6 board without a SWIM cable and an external power supply.

To reconnect your STM8S105C6T6 use connector CNn see Section 3: Daughterboard connection.

2.3 Power supply and power selectionThe power supply is provided by a USB connector. Jumper JP1 selects the VDD value (5 V or regulated 3.3 V) see Figure 9.

10/17 Doc ID 16361 Rev 2

2.4 Single touch sensing A touch sensing button TS1 is available on the STM8S-DISCOVERY (see Figure 10).

Figure 10. Touch sensing schematic

To disable the touch sensing interface and to use PC1, PC2 and PC3 as standard I/O, you need to unsolder the 2-1 connection and solder 2-3 connection on SB4 and SB3, you also need to unsolder the R2 resistor.

RC acquisition principle

The RC acquisition method detects a human touch on key touch sensor (TS1) by measuring the small variation of the touch electrode capacitance. Electrode capacitance is periodically charged and discharged through a fixed resistor (R6).

The capacitance value depends on the following parameters: electrode area (A), relative dielectric constant of the insulator (eR), the relative permittivity of air (e0) and the distance between the two electrodes.

For more information about touch sensing please refer to AN2927.
