To program the STM32F103C8T6 board, click on the Compile button and save the binary to the NUCLEO virtual disk.

Connect the NUCLEO board to your PC over a USB cable.

(The VDD_TARGET pin on the NUCLEO board CON4 does not work as source of power).

Provide power for the STM32F103C8T6 board through a 3.3V pin, 5V pin or over a USB cable.

That's why it's recommended to connect also the VDD_TARGET line when an external programmer such as a Segger J-Link is hooked up to program the board. That works with the ST-Link programmer but could potentially damage the target micro controller in case it's running at a lower voltage (e.g. Please notice that VDD_TARGET is not connected.

Connect the NUCLEO board CN4 connector to the STM32F103C8T6 board using flying wires as follows:.

Remove the two jumpers from the CN2 connector as illustrated in Figure 8:.

To do that, an additional NUCLEO board is needed (any type equipped with ST-LINK/V2-1 will do). You can use the NUCLEO virtual disk to program the STM32F103C8T6 board (drag and drop programming). Programming the STM32F103C8T6 board NUCLEO ST-LINK/V2-1 and drag & drop

Have a look at mbed-STM32F030F4 and Andy's hints for some good tips. Try to optimize your program until it's using less than 64kB flash memory. In order to fit into an STM32F103C8T6 board the used Flash should not exceed 64kB (depending on your actual board). Once the compilation is complete (started by clicking on the Build only button in the Compile drop list or by pressing Ctrl+B) you can visually check the size of used flash memory in the Program details - Build tab. Although it seems that majority of Blue Pill boards sold online usually feature 128kB Flash rather than 64kB. However, the STM32F103C8T6 is equipped with only 64kB. Keep in mind that the online compiler is checking for 128kB maximum flash size. Or click here to import this demo into your online compiler. Using the mbed online compiler to build programs for the STM32F103C8T6 boardĬreate a program as if it was for a NUCLEO-F103RB board (select NUCLEO-F103RB as target platform for the online compiler). Once saved to your local drive, change the extension from png to lbr.

Schematicīecause neither lbr nor zip files can be uploaded to mbed wiki pages anymore to download the eagle library right-click on the link and select Save link as. So to turn the LED on or off you have to set the DigitalOut to 0 or 1 respectively.

Arduino (green/white) and the additional naming labels are not indicated on the board.Īlso notice that the on-board LED is connected to pin PC_13 and, via a resistor, to +3.3V. Instead of 'PA_1' you can find the label 'A1' on the board). Please notice that in order to fit the small size board, the leading 'P' and the '_' characters are omitted from labels indicated on the board (e.g. SERIAL_RX=PA_3 I2C_SDA=PB_9 SPI_MISO=PA_6

For more details on pin definitions see Table 5 in the Datasheet. Maximum allowed I/O voltage levels (next to pin names) are courtesy of Thor Sten to help you avoid board damage.

Flexible board power supply: USB VBUS or external source (3.3V, 5V).

GPIO (32) with external interrupt capability.

The board is equipped with an STM32F103C8T6 microcontroller compatible with the NUCLEO-F103RB platform. It provides an affordable (about $2 on eBay) and flexible way for users to try out new ideas and build prototypes.
