In this project STM32 Primer1 can be used as colour mini-display. Device receive command from host PC via USB, draw some texts and graphics on small LCD display, return result message. Device firmware based on PrimerVirtualCom project with small changes. Virtual COM-port device driver must be installed on host computer before any using of this project.
Program or service from host (PC) send command to virtual COM port. Device parse this command and draw received text - computer state, CPU temperature, core voltage, firm logo or some other. Currently supported drawing only for strings and rectangles. Command format and parser support Line and Picture drawing, but it's not implemented. Some more commands (BackLight on/off, Pixel set, etc.) can be added as improvement.
