TM1640 16-bit digital tube driver module

Project Description Based on the 0.56-inch digital tube display module
of Tianwei TM1640 digital tube driver chip sold in Lichuang Mall https://www.bilibili.com/video/BV1N84y1a7oC/?vd_source=be70fa55ac113f4735a6b71fc42e5574 Reference code microprocessor data passed The two-wire bus interface communicates with TM1640. When CLK is high level when inputting data, the signal on DIN must remain unchanged; the signal on DIN can only change when the clock signal on CLK is low level. Data is always input with the low bit first and the high bit transmitted last. The starting condition for data input is that when CLK is high, DIN changes from high to low; the end condition is that when CLK is high, DIN changes from low to high. . This chip is not compatible with any existing bus protocol, so we need to implement the driver code ourselves. Attached to the project attachment is a driver code under the AT32F435 firmware library, which contains the timing and basic writing code of TM1640. You can follow This code is ported to other platforms. If used in an operating system, please be careful to enter the critical section to prevent interruption by operating system switching.
