The ESC-ECL software is a Simulink Blockset that provides a simple and fast way to generate C code from Matlab/Simulink models for selected families of STM32 microcontrollers. The blockset includes support for STM32 microcontroller peripheral interfaces. The hardware layer configuration is straightforward and quick, facilitating hardware implementation so that the user can focus on solving algorithmic challenges. ESC-ECL combines the advantages of STM32CubeMX—such as graphical peripheral configuration and access to the latest ST HAL libraries—with the benefits of Matlab/Simulink, including ease of implementation, simulation capability, and code portability. Using the ESC-ECL blockset in a project allows for easy and fast implementation of communication interfaces available on the STM32 microcontroller, such as I2C, SPI, UART/USART, USB, CAN/FDCAN, and Ethernet. ESC-ECL enables the use of STM32 hardware peripherals in algorithms, such as GPIO, ADC, DAC, TIM, and SDIO. An additional advantage is the integration of Direct Memory Access (DMA) for communication interfaces and STM32 peripherals, embedded within ESC-ECL. The ESC-ECL blockset also allows for the integration of the FreeRTOS real-time operating system into the project. Task generation, memory allocation, and the handling of semaphores and mutexes are pre-implemented within the blockset.
