This is the source code of how to drive a RAV4 VFD display by using STM32 chip, currently using so called "blue pill" with stm32f103c8t6 on board. Currently using the GPIO control, it should be able to using HW SPI interface. Maybe next step. This is project generated by STM32CubeMX with TrueSTUDIO project.
