CH32V003F4P6 Microcontroller: Completely Eliminate Ghosting in 74HC164 Driven Seven-Segment Displays
Many developers using the serial-parallel driving CMOS integrated circuit74HC164 have reported ghosting (segments that should not be lit are slightly glowing). It is better to switch to74HC595. However, it is possible to achieve ghost-free operation using74HC164 to drive seven-segment displays with the synchronous serial port of the STM32F103 microcontroller. The STM32F103 microcontroller is limited in … Read more
