Application of MYIR's i.MX 6ULL SOM in Teaching Devices

With the development of robotics technology, the application of robots in social production has been promoted. However, the application of robots face some issues such as difficulties in development and poor safety. The abundant components of the teaching device can easily solve the problem of difficult robot development, and the built-in monitoring function can provide safe usage guarantee. The requirements for teaching devices have also increased. However, the mainstream teaching pendant hardware configurations on the market are generally low, and the computing power cannot meet the needs of intelligent control. The capacity of the main chip is relative small, unable to store large capacity operating data for a long time. The software part also lacks data analysis capabilities. Additionally, there is a lack of support for peripheral devices, with limited interface functions, and limited ability to extended applications.

What is a teaching device? It is also called "a teaching Programmer", which is a handheld device used in robot control. In the motion control system of robots, the teaching device is connected to the control cabinet or motion controller through communication cables. By setting motion parameters and programming the robot's motion path, the robot can work according to the programmed process file, and it allows for real-time monitoring, adjustment, and emergency stop of the robot's motion. It can also be configured to a manual operation mode for real-time control of the robot's movement.

In response to customer needs, MYIR has provided a solution for the application of teaching device based on the MYC-Y6ULX-V2 SOM. The MYC-Y6ULX-V2 features NXP's i.MX 6UL/6ULL series MPU, equipped with a single Arm Cortex-A7 core that operates at speeds up to 800 MHz. It comes standard with 512MB DDR3 and 4GB EMMC flash, providing ample storage space. With parallel LCD display capability and a resolution of up to WXGA (1366x768), it meets the requirements of high computational speed, large storage capacity, and ease of operation for engineering machinery controllers. Additionally, the MYC-Y6ULX-V2 SOM offers rich interfaces including 2 CAN buses, 8 serial ports, 8 ADCs, and 4 I2Cs, allowing for customized solution designs based on customer requirements, effectively empowering the intelligent applications of machinery controllers.

The MYC-Y6ULX-V2 SOM provides driver support for the latest Linux 5.4 kernel version, with a well-developed software ecosystem. It has undergone extensive aging tests, temperature cycling tests, and power cycling tests, ensuring stable performance after testing. The SOM has a compact form factor, measuring only 37mm x 39mm, and is designed with a stamp hole package that is soldered directly to the baseboard, providing stability and resistance to loosening. This makes it suitable for the harsh industrial environment requirements of engineering machinery products. The SOM supports OTG and TF card for various programming methods and reserves 140 expansion interface pins, which include abundant peripheral resources for flexible application development.

Features of MYC-Y6ULX-V2
