Nucleo boards are fully supported by mbed and can be programmed by using online IDE, tons of available libraries. But this doesn’t seem necessary as there are many tools available starting with bare metal programming with IAR, KEIL, GCC or even better you can use platform to write and compile your programs online. One thing you cannot do (at least yet) is program with Arduino IDE.
USB can be selected to be as virtual COM port, mass storage or debug interface. The Nucleo board is split in to two parts – The Nucleo part with headers and core and Stlink part which can be used to program and debug target using USB cable. There is one user programmable LED and one button (+ Reset button) to get first blinky program working in no time. Other pins are brought out by using Morpho headers: Any Nucleo board have Arduino UNO compatible headers where most of Arduino shields can be plugged and used for fast prototyping. There are 512KB of flash and 96KB of SRAM on chip and can be clocked up to 84MHz.
Lets look at Nucleo-F401RE – one of four boards available now.įirst of all it features ARM Cortex-M4 STM32F401RET6 microcontroller which of course have FPU module and DSP instructions. The shape of Nucleo board is somewhat close to Arduino Uno, just a bit wider so it could carry two types of connectors. The idea was to get closer to Arduino interface, but still have ARM power and versatility. Programming STM32 Nucleo with Arduino IDE Till now, in this tutorial, we have installed STM32 Arduino core in Arduino IDE. You can select the Nucleo boards such as Nucleo-64, Nucleo-144, etc. STMicroelectronics Nucleo boards are another way of prototyping with ARM Cortex-M microcontrollers. To check if the library is installed properly or not, you can go to tools > boards > stm32 boards groups.
