Friends, which algorithm do you use to control the LEDs in this structure? I need your ideas. I have prepared a table of the LEDs' turn on order.

When I give the delay time greater than 300 for the code below (500ms or 1000ms), GetTick or HAL_Delay(500); functions do not work.If I make the time 100ms, 200ms or 300ms, it works.When I want to control the delay at longer times, the program does n...

Hal_Delay çalışmayı durdurdu ( STM32F030C6T6 )Forumda buna benzer birçok konu okudum ama bir çözüm bulamadım. Sanırım sorunun kaynağının bu olduğunu anlayalı 7-8 gün oldu. Hal_Delay() çalışmadığı için GetTick() fonksiyonunu da kullanamıyorum. Basit t...

I haven't been able to wait 500ms without affecting the timers for 7 days.In this block, doesn't PB14 become "0" after 500ms?Even if I use comment lines, it doesn't work.Note: volatile uint32_t Counter = 0;The "Counter" variable is incremented every ...

if(htim->Instance==TIM16) { Counter++; if(HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13)==0) { if(HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_2)==0) { if(PA10_On==0) { HAL_GPIO_WritePin(GPIOB, G...

First of all, thank you very much for your kind and detailed explanation.I have some problems.1. I do not know English. I am writing to you via Translate. That is why I cannot understand some of your technical statements. It is not understood when t...

Friends, I will give you the document you want in a moment, but I do not understand how this forum works. In the country where I speak my own language, we can understand what we mean very quickly without giving too much detail. Here, people either ha...

In LED display, segments are sent at once. Scanning is done as many times as the number of digits. In my design circuit, you have to scan 24 LEDs one by one. 24x5ms= 120ms causes very large flicker.

There is a real circuit. There is a transistor for common cathodes in the circuit. There are also forward resistors for the LEDs. There is no mistake in the design. I can also share the full design. I did not want to consult about the design. I opene...
