Shulou(Shulou.com)06/03 Report--

The emergence of STM32MP1 series has attracted the attention of many new and old STM32 users, but many people will worry about a problem: they used to be based on Cortex M series MCU, but they are not familiar with cortex-A processors and Linux systems. How to efficiently leap from MCU to MPU is a topic that everyone is concerned about.

As the official partner of ST, Mill Electronics launched the development kit MYD-YA157C, which consists of core board MYC-YA157C and backplane MYB-YA157C. The platform adopts STM32MP157 series of high-performance processors and provides rich interfaces such as high-performance display, Gigabit Ethernet, WIFI/ Bluetooth, RS232/RS485/CAN and so on. Suitable for the product definition of the application scenario, stable and reliable hardware design, rich software and learning resources, can help you easily achieve leapfrog, is a recommended STM32MP1 development board.

1. STM32MP157 super chip

The development platform uses ST STM32MP157AAC3 processor as the main control platform, which is the first MPU launched by ST in 2019. It is also a super dual-core cortex-A7 plus single-core M4 chip. The main frequency can reach 650Mhz. The chip is rich in resources to meet the daily needs of users for image interface, and supports a variety of memory interfaces and rich communication interfaces.

Mir's board has a huge amount of memory, including 4GB eMMC and 512MB DDR, which can load rich system resources, as well as power management IC and Gigabit Ethernet PHY, which can give full play to the strong performance of the chip.

2. Application-oriented, rich in functions and multiple interfaces

The platform can be widely used in industrial manufacturing, medical applications, smart home and consumer electronics. Multi-core architecture is an ideal choice to develop open source software applications in real-time and power-constrained subsystems. at the same time, it also has a 10-year rolling renewal of industrial-grade supply commitment that consumer grade does not have.

The MYD-YA157C development platform has rich functions and highly integrated interfaces, which makes full use of the main IO ports of the core board and realizes the HDMI+RGB+MIPI interface on the basis of 3D GPU support, which is widely used in HMI design. For the field of industrial control communication, there are WIFI and gigabit network interfaces, RS232, 485and isolated CAN interfaces on the board, which can be applied to the development of industrial Internet of things.

3. Multiple sets of software supporting Wei Dongshan teacher's teaching resources

Mir Electronics provides rich software resources to help achieve product development as soon as possible, one board, multiple sets of software resources: ST official system, Ubuntu,MEasy IOT and other software, as well as MQTT protocol and power protocol Demo.

The development board is also equipped with teacher Wei Dongshan's teaching resources. Mill Electronics and Mr. Wei Dongshan, a specially appointed lecturer from a famous training institution in China, have jointly launched a series of courses, which are taught by Mr. Wei passionately and are rich in document and video resources.
