Posted on June 17, 2018 at 12:09I'm reading data from a UART with DMA and want to write that data to an SD card (on a F722). Since the data is much longer than my buffer, I chose circular buffer for the DMA.The problem now is that I need to save the...
Hi all,my SDRAM setup seems to work EXCEPT that I have a strange behavior:When I write any value (8, 16, 32 bit) to an address (example 0xd000004),it in fact gets written to the address - 2, in this example 0xd0000002.All written bytes are readably @...
Hi, I want to set 3 channels of adc and transfer data via dma to buffer.But I want to read randomly, sometimes only ch1, sometimes only ch3 etc. One channel at time. And fill buffer with data from one channel.Do I have to set:-adc continous - dis...
Hello i am working on stm32h743 , and in it ADC DMA stop working but when i try to start again i does't.what is the problem in it?
Hi,I want to use lfn feature in sd card and i use stm32f4 for this purpose i set _USE_LFN to 1 and _MAX_LFN to 255 . when i create the file , file is created but when i want to return file name , returns wrong.please guide me, how to return file name...
Specifically I'm looking for any app notes on using the USB s/w HAL and drivers on a STM32F7 based processor.
Hi,I am using STM32F103RDT6 for my project. I need only two seperate uart lines and 2 Gpios for to connect 2 RS485 transceivers.I need TX ,RX pin only. So what about the CTS & RTS pin. can I make that as float?There is 2 boot pins in the IC. how I co...
Hi all!I have NUCLEO H743ZI board, and I am playing with HRTIM.I am trying to take advantage of fault logic, found in HRTIM module. HRTIM can have GPIO hardware input, which can shut down all HRTIM outputs, without ANY software overhead. Now, I would...
I would like to know the maximum number of quadrature encoders (looking for up to 8) that can be supported with a STM32F777ZITx. Any other STM MCU's that do better? Can more be supported if using LL interfaces instead of HAL?RE: HALI am referring to ...
