Quick start

Before installing and using the product, accept the Evaluation Product License Agreement from the www.st.com/epla webpage. For more information on the STM32C0116-DK Discovery kit and demonstration software, visit the STM32C0116-DK product webpage.

5.1 Getting started
Follow the sequence below to configure the Discovery kit and launch the demonstration application (Refer to Figure 3 for component location):

Check the JP1 jumper position on the board (Refer to Table 4).
For the correct identification of the device interfaces from the host PC and before connecting the board, install the ST-LINK/V2-1 USB driver, available on the www.st.com website.
To power the board, connect the Discovery kit to a PC with a Type-A to Micro-B USB cable through the CN3 USB connector of the board.
Then, the LD1 COM red LED lights up, and the LD3 green LED blinks.
The demonstration software, as well as other software examples for exploring features, are available in STM32C0116-DK product web page.

6.3 Embedded ST-LINK/V2-1
The embedded ST-LINK/V2-1 supports only the SWD for STM32 devices.
The ST-LINK/V2-1 programming and debugging tool is integrated into the STM32C0116-DK Discovery kit. For information about debugging and programming features, refer to the user manual ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 (UM1075), and the technical note Overview of ST-LINK derivatives (TN1235), which describe in detail all the ST-LINK/V2 features.
The additional features supported on the ST-LINK/V2-1 are:

USB software re-enumeration
Mass storage interface on USB
USB power management request for more than 100 mA power on USB Known limitation:
Activating the readout protection on the STM32 target prevents the target application from running afterward.
The target readout protection must be kept disabled on ST-LINK/V2-1 boards.

6.3.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows 7® and Windows 8® , is found at www.st.com. For Windows 10®, it is not necessary to install the driver, as the ST-LINK is automatically identified.
In case the STM32C0116-DK Discovery kit is connected to the PC before the driver is installed, some Discovery board interfaces may be declared as “Unknown” in the PC device manager. In this case, the user must install the dedicated driver files, and update the driver of the connected device from the device manager as shown in Figure 6.
Note:
Prefer using the “USB Composite Device” handle for a full recovery.

6.3.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the in-situ upgrade through the USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the STM32C0116-DK Discovery kit and periodically, to stay up-to-date with the latest firmware version.
6.4 Power supply
The STM32C0116-DK Discovery kit is designed to be powered using the CN3 ST-LINK/V2-1 USB connector.

6.5 Board functions
6.5.1 LEDs
LD1 ST-LINK COM LED
The LD1 green and red bicolor LED provides information about the ST-LINK communication status. LD1 default color is red. LD1 turns green to indicate that the communication is in progress between the PC and ST-LINK, with the following setup:

Blinking red: The first USB enumeration with the PC is taking place
Red LED ON: When the initialization between the PC andST-LINK is complete
Blinking red or green: During programming and debugging with target
Orange ON: Communication failure

LD3 user LED
This green LED is connected to the PB6 GPIO of the STM32C011F6 microcontroller. To light this LED, a LOW logic state must be written in the corresponding GPIO.
6.5.2 Push-buttons
B1 Reset/user button
This push-button is connected to NRST (PF2-NRST) and is used to reset the STM32C0 Series microcontroller or to generate a user event.
B2 joystick
This joystick is a 5‑way rock switch using a single ADC input pin (PA8). Push-in “Select” can be used as a digital user button and EXTI wakeup interrupt. The joystick position for the ADC value refers to Table 5.

Table 5. Joystick position versus ADC value

Joystick position	Measurement ratio	ADC value (In volts)
Select	0	0
Left	0.2	0.67
Down	0.4	1.32
Up	0.61	2.01
Right	0.8	2.65
No key pressed	1	3.3

6.5.3 IDD current consumption measurement
The IDD‑labeled JP1 jumper is used to measure the STM32C0 Series microcontroller consumption by removing the jumper and by connecting an ammeter.

JP1 ON: The STM32C0 Series microcontroller is powered by 3V3 voltage (Default).
JP1 OFF: An ammeter must be connected to measure the STM32C0 Series microcontroller current. If there is no ammeter, the microcontroller is not powered.

6.5.4 Solder bridges
The solder bridges are located on the top layer of STM32C0116-DK. Their configuration appears in Table 6.

STM32C0116-DK board information

9.1 Product marking
The stickers located on the top or bottom side of the PCB provide product information:

Product order code and product identification for the first sticker
Board reference with revision, and serial number for the second sticker
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision and “zz” is the assembly revision, for example B01. The second line shows the board serial number used for traceability. Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference designs or in production.
“E” or “ES” marking examples of location:
On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the STM32 datasheet “Package information” paragraph at the www.st.com website).
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
