Hello friend,
i want to make display p10 using atmega 328 control board, and using ic buffer display 74hc245, do you have schematic how to use this ic, please help me, i already searching and googling how to use this ic as buffer display.
thanks again guys for helping me...
Your topic was MOVED to its current forum category as it is more suitable than the original
Please explain what is p10 and how a 74HC245 is related to a buffer display. The 74x245 has no memory included.
A p10 display sometimes referrs to an LED matrix display where the LEDs are placed every 10mm horizontally and vertically. Is that what you mean? Do you intend to build a matrix like this yourself, instead of buying a ready-made p10 matrix?
74hc245 is not really a useful chip for building your own matrix. You could consider max7219 chips. Each chip can light 64 LEDs and you can connect many chips to the same Arduino pins.
yes i want to make text running smoothly
i want to add 74hc245 to remove flickering running text for dmd p10
Would you please explain how using 74hc245 removes flickering?
74hc245 can be use for buffering moving charcater
You seem very confused. The video you posted a link to shows a ws2812 LED strip driven by an ESP microcontroller. Sometimes a 3.3V-5V logic level shifter is required to make this combination work without errors in the data signal.
You mentioned a p10 dot matrix display and a controller based on atmega328. Please explain how you believe these two scenarios are similar.
okay.. im realy confuse indeed, i want to make two text static and scrolling display running at same time, for example for display " MONDAY | 14th February 2022 - HAPPY VALENTINE"
monday| == static display and message 14th february happy valentine is scrolling text. can i make it without any additonal componen while i am using arduino uno.
Buy her flowers and chocolates. Work towards having the p10 displays working for valentine's Day 2023 or 2024. This will give you enough time to build your knowledge and skills. Perhaps at that time you can give her your marriage proposal using the led matrices. That would be a wonderful thing I think. I hope she will think that also.
this is actualy iam talking about, they are 3 major component they are :
eeprom 24C512, atmega 328, and ic sn74hc245, for communication we use rs485 and i am using rs485 ttl converter, and its working..
Display P10 Arduino uno scroll two text static and scroll in one line - YouTube this is my video while i am building this project, i am using arduino uno r3, but seem they run not smoothly
