I cannot help but test a little more how nicely the #Microwindows #NuttX port works. So there are a few more screenshots from running TECHNIC I firmware on NuttX under #QEMU. The screenshots include even dosing state where special keys for test build are used to emulate syringe diameter and other HW sensors. The original HW has been based on our PIMX1 i.MX1-based CPU board and more about the original design decision can be read in the article RTEMS Executive and XML-Based GUI in Medical Instrument Firmware and related Slides. The second MCU used in mutual supervision loop and control has been MSP430 for low consumption. The original design used a monochrome LCD, later models used a color LCD as shown in the emulator. The instruments have served in hospitals for decades. PIMX1 board has been used with #RTEMS and for less critical applications with our #Linux port.
