How to get started with ARM Cortex-M and RTOS?

The ARM Cortex-M series of microcontrollers are extremely popular in embedded systems due to their low cost, low power consumption, and good performance. Using a Real-Time Operating System (RTOS) allows you to better structure your application software and take advantage of features like multithreading and inter-task communication. Here is a step-by-step guide on how to

Can ARM Cortex-M processors do division?

Yes, ARM Cortex-M processors are capable of performing division operations in hardware. While earlier Cortex-M0 and Cortex-M0+ processors lacked a hardware divider, Cortex-M3 and newer Cortex-M processors include integer division instructions that can divide 32-bit values efficiently using a single cycle hardware divider unit. Hardware division support in Cortex-M processors The Cortex-M processor series is

Understanding Interrupt Latency and Jitter in Cortex-M

Interrupt latency and jitter are important performance metrics to consider when using Cortex-M processors. Interrupt latency refers to the time delay between the assertion of an interrupt request and the start of the interrupt handler execution. Jitter refers to the variation in interrupt latency from one interrupt to the next. Minimizing interrupt latency and jitter

What is the maximum frequency of cortex-M0?

The Cortex-M0 is an ARM microcontroller core designed for low-cost and low-power embedded applications. It is the smallest and most basic member of the Cortex-M processor family. The maximum clock frequency of the Cortex-M0 core depends on the specific implementation in silicon by ARM partners and vendors. However, the typical maximum frequency ranges from 50

How does one do integer (signed or unsigned) division on ARM?

Integer division on ARM processors is done using the SDIV and UDIV instructions for signed and unsigned division respectively. Here is a detailed guide on how integer division works on ARM and how to utilize the division instructions. Overview of Integer Division on ARM On ARM processors, integer division is done in the Arithmetic Logic

How to properly enable/disable interrupts in ARM Cortex-M?

Enabling and disabling interrupts is a critical aspect of working with ARM Cortex-M microcontrollers. Interrupts allow the processor to respond to events and requests from peripheral devices. However, incorrectly enabling or disabling interrupts can lead to issues like race conditions, deadlocks, and reduced performance. This article provides a step-by-step guide on how to properly enable

How does bootloader work in ARM Cortex Series?

The bootloader is a crucial software component in ARM Cortex-based systems. It is responsible for initializing the hardware, setting up the environment for the operating system, and eventually loading the OS kernel. Understanding how the boot process works provides valuable insight into the startup sequence and configuring the bootloader for different needs. Overview of the
