I am using STM32H753.My TIM2 is in Encoder mode, and I give two external signals from my incremental encoder to TIM2_CH1 and TIM2_CH2. My TIM2 is counts perfectly (Up or Down) when I move the encoder clockwise or anticlockwise.Now i want to syncroniz...

I use STM32H753 and USART1 with DMA to receive data of unknown length (Min: 8 bytes Max: 512 bytes) from PC. Data will be sent in burst after every one second. My baud rate is 9600. So approx 1ms per byte.So, maximum, I'm going to get all the data in...

I am using STM32H753 for driving 800x480 TFT LCD. Currently I am using External SDRAM for my FRAME BUFFER. I am using DMA2D and TFT LCD module of MCU.#define LCD_LAYER0_FRAME_BUFFER ((int)0xC0000000)#define LCD_LAYER1_FRAME_BUFFER ((int)0xC0300000)My...

I need to run TIM8 on Encoder mode. My encoder has two channels (A and B 90 degrees), So I have used two channel TIM_CHANNEL_1 and TIM_CHANNEL_2 as encoder input (it will use encoder as a clock for TIM8) and my timer is working fine and CNT is updati...

I want demo code for STM32F746 Discovery kit as per follow.1) using lwip for TCP Server / Client.2) Not using RTOS.Demo code available for STM32F756-EVAL at Projects\STM32756G_EVAL\Applications\LwIP\LwIP_TCP_Echo_Client.This demo code is perfect but ...

@Karl Yamashita and @SofLit Thanks for your replay.I need to use other timers for scanning other external Eight Signals with respect to Encoder signals ( As Input capture ) So that i can get encoder count (Or encoder position) at Rissing or Falling ...

Finally, I got success with option 4 without any errors and minimum CPU intervention. The code is attached. (Only the required lines of code are specified. But you can implement it to your code)@JMeye.2 Link2 ( ST's Example) is very useful for me....

Thank you to all for replay@JMeye.2 AND @Piranha You mean I need to use Combinetion of 2 + 4. ?Half and Full buffer interrupt and also give interrupt for Ideal ( i.e. HAL_UARTEx_ReceiveToIdle_DMA ).I will check and inform.But as my previous obser...

STM32 Timer encoder mode with synchronization

STM32H7 UART DMA Receive unknown length of data.

How calculate TFT LCD Frame buffer size. Can we allocate it in internal memory. ?

STM32F746 Using TIM8 in Encoder mode is not working with Input capture on both edge ???

Is there any tested example for STM32F746G-DISCO for TCP server/client without RTOS..?
