This is a 5-inch digital tube driver circuit I just made. The segment code is driven by 595+573+2803, and the bit code is made by PMOS4953. There are 4 digital tubes in total. Only one of them is show
:'( There are several integrated chips that look like switch tubes, but the manufacturer on them is erased. I only know some words written on them: 1.B3T7S 2.N4U3W 3.8A78. I can't find any information
I am a PFGA beginner learning VHDL. For FPGA programming, it is the behavior level of hardware description. Regardless of the underlying hardware structure, we still need to construct various basic ci
