After finding some time for research activities, we decided to simplify and thereby improve our main products based on ARM microcontrollers (STM32), which are FlashOnline, CobraRTP Honda Edition and MotronicRT.
Background
All our devices with a USB interface communicate with a PC as a USB-COM bridge (virtual COM port). To do this, we used USB controllers as separate microcircuits, which are tasked with coordinating communication between the PC and the device's processor.
