Choosing the Best ARM Cortex M Series for Beginners in Embedded Programming: STM NXP or Microchip Atmel
The initial steps in embedded programming can be both exciting and challenging. Given the wide array of options, a beginner might wonder which specific ARM Cortex M series is best suited for them. This article will explore two popular contenders: STM microcontrollers (MCUs) from ST Microelectronics and Microchip Atmel MCUs. We will also discuss why AVR or PIC might be a more suitable starting point for those new to embedded systems.
Why Start with AVR or PIC?
For absolute beginners, high-level languages and simpler architectures like AVR or PIC can be a better starting point. These microcontrollers offer a more straightforward learning curve, requiring less “voodoo” to configure and get set up. This is crucial for initial learning because it reduces frustration and makes the process more enjoyable.
STM NXP Cortex M MCUs: A Comprehensive Choice
For those looking to dive into ARM architecture, STM NXP provides a robust set of Cortex M MCUs. With over 1,200 different derivatives in their product portfolio, they offer a wide range of options for different projects and applications. ST Microelectronics supports their MCUs with several integrated development environments (IDEs), including Keil uVision, IAR, and STM32Cube IDE. They also provide evaluation kits to help users learn and evaluate their MCUs effectively.
As someone who has worked professionally with STM Cortex M MCUs, I can attest to their versatility and reliability. These MCUs are ideal for higher-end projects and offer extensive support through comprehensive documentation and evaluation kits.
Microchip Atmel Cortex M Ecosystem
Microchip Atmel also offers excellent Cortex M MCUs with a strong ecosystem. They provide the MPLAB X XC compilers, extensive libraries, and application notes, making it easier for beginners to start. The dsPIC series, designed specifically for motor control, is another highlight. Additionally, Microchip’s devices are supported by the MPLAB X environment, which offers a wide range of tools and features for project development.
For beginners, Microchip Atmel supports MCUs available in DIP packages, which is a significant advantage. This means initial development can be done on a breadboard or custom-made PCB, making it easier and more accessible for those new to the field. It’s also important to note that other companies offer similar solutions, but Microchip leads in terms of the number and variety of devices.
Recommendation and Conclusion
While both STM NXP and Microchip Atmel offer excellent options, Microchip Atmel is particularly well-suited for beginners in embedded programming. The availability of DIP packages and extensive application notes make it a user-friendly choice. Additionally, the best starting point might be spending more on a demo kit. These kits come with everything ready to go, eliminating the headache of PCB design and providing a head-start in your project.
Microchip Atmel’s rich knowledge base and comprehensive application notes are exceptional resources for learners. They provide deep insights into various applications and areas of interest, making them invaluable for both beginning and advanced users.
In summary, whether you're a beginner or looking to expand your knowledge in embedded systems, Microchip Atmel’s Cortex M MCUs offer a compelling and supportive ecosystem. Starting with a DIP package and demo kit can make your initial adventures in embedded programming much more manageable and enjoyable.
