![]() If you wish to use say SPI or I2C interfaces then you are required to use only the pins shown in the datasheet for your NUCLEO board so that the compiler can arrange the requested hardware functions onto the specific pins - that is mandatory. Do respective the max voltage ranges (most pins are 5 volt tolerant but play it safe and consider to use 0 to +3V3 for most of your experiments. The use of such port pins as I/O (Input / Output) is very straightforward using the MBED library. Soon you will learn how easily MBED shelters us from the many lines of complex code to achieve the desired tasks. This should now flash the PC_8 pin on your Nucleo board.ĭo try the example and notes and certainly post back if you have any issues. Nucleo pinout Pins Legend You can find more details on the available pins and labels in the PeripheralPins.c and PinNames.h files. ![]() This interface is supported by the openocd version included in the Zephyr SDK. Flashing Nucleo F446RE board includes an ST-LINK/V2-1 embedded debug tool interface. you could also reverse the LED and connect the ANODE to your local +3.3 volts but then to turn the LED ON, you will needĬompile -> drag & drop the binary onto the target drive letter. Applications for the nucleof446re board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details). with this wiring when PC_8 = 1, you are applying +3.3 volts onto PC_8 which will then turn the LED ON and if 0, LED will be connect the ANODE (positive / long lead of the LED) to PC_8 and the CATHODE (negative / short lead) to ground How, replace the LED1 value with a port pin that you wish to use from the NUCLEO MBED page for your target board:ĭigitalOut myled(PC_8) // attach a LED with a current limit resistor of 390 ohms or higher to the noted pin on NUCLEO ![]() Pick a board that has I2C pins exposed and make a note of their numbers and locations. Next, let us say you wish to change the LED1 pin to your custom defined port pin. Now we will connect the I2C slave board that will receive the data from the master board. The file does not include the alternative pin combinations with different names like in the library for VSC. This is important to be sure you upgrade to the latest library by MBED. The PWM-pin combinations are stored in: AppDataLocalArduino15packagesSTM32hardwarestm321.9.0variantsNUCLEOF446REPeripheralPins.c. Be sure to select the MBED library inside this imported program and the select UPDATE using the right side of your compiler. You can review the Nucleo board details and assign a pin to be an output using the respective port pin name.įor example, IMPORT this quick demo (use the BLUE BUTTON on the right side of the screen once you land on the following webpage to import the quick demo into your cloud space account with MBED):īy default, if you select the target NUCLEO board that you presently own, the LED1 value will automatically map to a working LED supplied with your kit. Then review the many examples on this website including the COOKBOOK and HANDBOOK webpages at the top of this website to assist you in learning quickly about the benefits of MBED. Review the schematics for your Nucleo board from the following link:Īlso suggest to review this quick summary of the pins available through the Nucleo board with your CPU: Please review the following landing page for your STM32F44RE Nucleo board: Each of these value added services enable Strato to deliver the best products in the market today.Hello Adhelia.
