Qt for Memory-Constrained Devices
Qt for MCUs should better be called Qt for Memory-Constrained Devices, as Yoann Lopes, the Technical Program Manager for Qt for MCUs at The Qt Company, pointed out in a conversation in mid April. Qt for Memory-Constrained Devices gives a clear hint where The Qt Company wants to position Qt for MCUs. You should expect Qt for MCUs to run on both microcontrollers and low-end microprocessors in the medium term.
Yoann highlighted that the main driver for companies to use Qt for MCUs is cost. Unsurprisingly, Qt for MCUs is used for the HMI of high-volume consumer devices like dishwashers, washing machines, ovens, refrigerators, coffee machines, printers, e-bikes, e-scooters, wearables (see EM Microelectronic case study), motorcycles and oximeters. 50 cents more for a more powerful SoC make quite a difference when you sell one million devices per year.
