General description: In recent years, one of the main trends in microcontroller designs has been the use of ARM7 and ARM9 chips as general-purpose microcontrollers. Today, IC manufacturers have introduced more than 240 ARM-based microcontrollers. ST Microelectronics has just launched the STM32 series, the first microcontroller based on the new generation ARM Cortex-M3 core designed by ARM. The ARM Cortex-M3 core is an improvement of the traditional ARM7 core, which has brought great success to ARM. The STM32 series sets new standards in performance, cost, and the ability to meet low-power applications and demanding real-time control. The ARM7 and ARM9 chips are designed by semiconductor manufacturers with their own solutions, especially in handling special interrupts (exceptions) and normal interrupts (interrupts). Cortex-M3 provides a standard microcontroller core that provides the most important, general part of a microcontroller. ARMVN The basic architecture of SMT32 - ARM Cortex M3 includes an interrupt system, SysTick timer (designed for real-time operating systems), a debug system and a memory map. The 4Gbyte address space of Cortex-M3 is divided into regions for program code, SRAM, peripherals and system peripherals. Currently, CEE Center has 8 ARM 7 kits for practice and internship for students. The kit includes basic modules for training such as: single LED, matrix LED, 7-segment LED, LCD, ... Students can come to the center to be introduced and practice on the Kit.
