Raille display device design based on STM32

In order to keep the display apparatus reliability of reading braille point, reduce the production cost, improve the penetration rate, based on the mini stepper motor as the driving mechanism, we design a based on the STM32 braille display device. This paper first describes the overall design scheme of the blind to read and the assembly plan, and the hardware design and the function of each module is introduced, at the same time, the embedded software development and implementation process. And sets up a physical model for verification, the apparatus succeeds in converting English characters into corresponding braille raised dots, resulting in helping the blind to read electronic texts.
