Hi all,How loop back handled in hal layer if uwTick reach to the max limit HAL_MAX_DELAY=0xffffffff
Resolved! DMA UART RX idle line interrupt earlier
Hi,i have been using F030C6 with 1 uart and make DMA works. but when i received a modem message( like AT+CPIN? e.g.) DMA stops 2 or more times. We can see the image below that i put one toogle pin to show when DMA interrupt occurs.my question is how ...
STM32H7 - SPI test will not work unless I add pull down resistors to the MISO line
I have a test running on a Nucleo-H743ZI2 board which consist on a SPI master and a SPI slave sending data to each other. In particular, the master sends the slave the following sequence: {0xaaaaaaaa, 0x55555555} and the slave sends the master the op...
STM32H750B-DK sample multiple GPIO with DMA
Hello thereI am trying to port a logic analyzer from STMF407: https://code.google.com/archive/p/logicdiscovery/to work on my STMH750B-DKI even found some pins I (think) I can use (PB4,PB6,PB7,PB15 (right arduino connector (D0,D1,D10,D11)I tried to po...
STM32Cube IDE I am converting a basic program that I have written ages ago running on a CUBLOC CB30 connecting to a Picaso processor by 4D Systems (4.3inch touch display) I am converting it to c using STM32F401 Nucleo-64.
The serial output sent to the uart in the 4D displayis typically a string consisting of the following 3 items,#define Put_string &H00, &H18Const m_Alarm_Set As String = "Alarm set" #define NUL ...

The data is not coming on MOSI line when using the DMA forSTM32H7
Hello,I am trying to transmit data to DAC using SPI DMA method on STM32h745 I tried all the methods that mentioned on forum. But i did not get the data on MOSI pin, when I use the polling method the data is successfully transmit .const uint16_t addr[...
STM32H7 ADCs with DMA when D-Cache enabled
Dear all,I am trying to configure ADC1, ADC2 (ADC1 and ADC2 in multimode) and ADC3 running simultaneously with DMA.I have a running code for STM32F7 series and I assumed that I could use DMA in the same manner but DMA cannot store data taken from ADC...
