, can you help to tell me what is going wrong, sincerely ask,
CodePudding user response:
Problem has been solve thank thank
CodePudding user response:
The building of digital tube display not all is how to solve
CodePudding user response:
Digital tube can be decoded with static drive, because the simulation non-food, scanning mode will display looks is not complete
