Currently, I am planning to work on a system, in which we will be gathering the data from the multiple sensor for more than 15 parameters, based on the sensor value we will be controlling the actuators.
Some sensors have higher priority than others, and the output from the sensor values should be displayed in the color LCD screen in real time.
When we have less sensor data I am comfortable using ARM Cortex-M4 based controllers, STM32 controllers from STMicroelectronics are my favourites. Now, as we are planning to have a feedback control system and the real-time display of the value of the sensor, a real time operating system (RTOS) programming will be required. TouchGFX is a very good tool to display the value in the LCD display. I need your suggestion regarding which system should be selected for the above-mentioned project. (basic embedded, embedded with RTOS, embedded Linux, PLC, National Instruments controllers / LabVIEW etc, is there anything apart from what I have mentioned).
For a pneumatic based system, I have heard PLC based systems are very effective. Even Cortex-A based processors ( Linux based embedded systems) like Raspberry-Pi and Beaglebone can be used. If you could help in giving direction regarding which kind of system should be used for the above-mentioned application it would be great, and if there is any rule of thumb in selecting the one, please help with it.
I am curious about what kind of processors are used in standalone embedded devices such as ultrasonic machines and mechanical ventilators. How does an engineer program the touch screen, they must be using tools like QT?
If you have any knowledge regarding the industry-standard tool, please reply.
