So far, the project has integrated LVGL with STM32F407 and also supports touch screens using STM32F407 + SPI for resistive touch screens. Therefore, integrating the touch screen with LVGL is a natural progression. You can refer to the official documentation at https://docs.lvgl.io/master/details/main-modules/indev/overview.html#indev-creation. It is simpler to refer to an official example template, especially for touch … Read more

Recently, Renesas Electronics announced the launch of the RA0L1 microcontroller (MCU) product line based on the Arm® Cortex®-M23 processor. The RA0L1 microcontroller operates with a mode current as low as 2.9mA and a sleep mode current of only 0.92mA. Its fast wake-up feature reduces standby power consumption to 0.25μA, achieving a 90% reduction compared to … Read more
Click the blue text to follow us When using Siemens touch screens, many engineers find that their response speed is noticeably slower compared to certain brands (such as MCGS). This is primarily because the default variable acquisition cycle for Siemens touch screens is set to 1 second. This delay is particularly evident in scenarios requiring … Read more
The configuration software for Mitsubishi touch screens is: GT Designer3 This is the screen creation software used for the GOT2000 series and GOT1000 series. This software allows for project creation, simulation, and data transfer between the GOT and other devices. Here, we will directly explain the editing of the configuration interface. 1. Create a button … Read more
How to Operate the Control Cabinet of a Shaking Table? A Practical Guide with PLC and Touch Screen Easy to Understand for Beginners! In industries such as mineral processing and coal selection, the shaking table is the “main sorting force,” and its “brain”—the PLC and touch screen control cabinet—directly determines the sorting efficiency and product … Read more
