The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-32 board is a low-cost and easy-to-use development kit used to quickly evaluate and start a development with an STM32 microcontroller in LQFP32 or UFQFPN32 package. The Arduino™ connectivity support and ST Morpho headers make it easy to expand theįunctionality of the STM32 Nucleo open development platform with a wide choice of Microseconds for one run through Dhrystone: 9.The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. Microseconds for one run through Dhrystone: 10.70 Dhrystone Benchmark, Version 2.1 (Language: C)Įxecution starts, 300,000 runs through Dhrystone.And the result of two tests I did, one with Dhrystone and another from the SpeedTest video, are as follows: This program is here to compile something inside these microcontrollers in Arduino. This is a measure taken from some generic operations. The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone. Dhrystone became a representative of overall processor performance (CPU). Weicker, which is intended to be representative of (integer) system programming. This is unlike the Arduino Due, which needs a genetic processor to do that.ĭhrystone is a synthetic computer benchmark program developed in 1984 by Reinhold P. * I highlight here the separate FPU of STM NUCLEO-L476RG, which means that the chip makes trigonometric calculations with amazing speed. GPIO (51) with external interrupt capability (ART Accelerator ™) allowing 0-wait state execution from Flash memory Total DC Output Current on all I / O lines: 130 mAįlash Memory: 512 KB all available for the user applications I have used this model in videos: Nema 23 Stepper Motor with Driver TB6600 with Arduino Due, and SpeedTest: Arduinos - ESP32 / 8266s - STM32, with STM NUCLEO-L476RG, which is an ARM Cortex-M4 Ultra Low Power, and is in the image on the right side.ĭigital I / O Pins: 54 (of which 12 provide PWM output) Here is a comparison with the Arduino Due, which is an ARM Cortex-M3.

I've already ordered this chip, and I hope to talk about it soon. Just to illustrate, I show the details of an STM32F746G DISCOVERY, which I consider a beast. Also, I’ll explain the main characteristics of the STM32 Kits. So, while working with two versions of this powerful microcontroller, I’ll show you how to install the Arduino Core in the STM32 family. The STM32L432KC is identical to the Arduino Nano and the STM32L476RG, which have equivalent IOs to the Arduino Uno. In this image, we have two versions of L4. It implemented the Core Arduino in the chip, which enables programming through the Arduino IDE. But while researching more about it, I discovered something that the manufacturer STMicroelectronics does not disclose. I already talked about this microcontroller in the video, “The easiest way to program a microcontroller!” In the video, I showed how to program the STM32 L4 with MBED. This allows for a very efficient management of energy, and with high performance. Thus, it spends little energy and shows why this STM32 is incredible! It spends microamps and has a system inside that can identify the expense of each chip part. I want to start this article explaining that this letter L (of the L4) means Low (or, basically, Ultra Low Power).
