Real-time operating systems (RTOS) are designed to handle time-critical tasks with predictable interrupt latency. High interrupt latency can cause problems in real-time applications, resulting in missed deadlines or other timing issues. There are several techniques that can be used to reduce interrupt latency in an RTOS: Use Hardware Interrupts Judiciously Hardware interrupts are the main

The program counter and link register are two important registers used in ARM processors to handle program execution. While they serve complementary purposes, there are key differences between the two. What is a Program Counter? The program counter, commonly abbreviated as PC, is a processor register that contains the address of the next instruction to

The simple answer is no, Cortex-M0 does not have hardware support for floating point operations. The Cortex-M0 is one of the smallest and simplest Arm Cortex-M processor cores, optimized for low-cost and low-power microcontroller applications. It is an entry-level 32-bit ARM Cortex-M processor that only supports a reduced Thumb instruction set without floating point unit

The ARM Cortex-M0 is one of the most popular ARM processor cores used in microcontrollers and other embedded systems. It is an extremely energy efficient 32-bit RISC CPU that is widely used in IoT and wearable devices. One of the key things embedded systems developers want to know about any processor is – how many

The Arm Cortex-M0 is a 32-bit ARM processor core licensed by Arm Holdings. It is aimed at microcontroller applications that require a low power, low cost CPU with good real-time performance. The Cortex-M0 is the smallest and most energy efficient ARM processor available, making it well suited for IoT and wearable devices. One way to

When configuring the SPI (Serial Peripheral Interface) on an ARM Cortex-M0 chip to communicate with an external device, a common issue that arises is the SPI outputting 16-bit data instead of 8-bit as expected. This can occur if the SPI is not properly initialized and configured in the software. In this article, we will explore

Getting started with ARM Cortex programming using embedded C is easier than you think. With the right tools and basic knowledge, you can start building your own ARM-based applications in no time. The key is having a development board, compiler toolchain, and IDE. Once set up, you can begin coding in C/C++ and debugging your

The ARM Cortex architecture provides two instructions for entering sleep or low power mode – WFE (Wait For Event) and WFI (Wait For Interrupt). Understanding the differences between WFE and WFI is important for optimizing power consumption and wakeup latency in ARM-based systems. What is WFE? WFE (Wait For Event) instructs the processor to enter

The ARM Cortex processor architecture provides two low-power states for reducing power consumption when the processor is idle: Wait For Interrupt (WFI) and Wait For Event (WFE). The key difference between WFI and WFE is that WFI simply puts the processor to sleep until the next interrupt wakes it up, while WFE allows the processor
