Hi,I'm trying to use SPI to communicate between two boards. On the MASTER side, i am using the HAL_SPI_Transmit(&hspi4, (uint8_t*)TxData,sizeof(TxData),100); and on the slave side i have enabled the interrupt, HAL_SPI_Receive_IT(&hspi4,RxData,1); The...
Hey,I have a discovery board (https://www.st.com/resource/en/data_brief/32f429idiscovery.pdf)This board has an on board 64 MBit SDRAM.Now i have read in other posts that RAM extension is not possible in an SPC line MCU. However what about the STM32F4...
have written this ARM assembly code. It is supposed to put the Fibonacci sequence numbers in R4 register. I'm trying to implement this C code in assembly:int fibbonacci(int n) { if(n == 0) return 0; else if(n == 1) return 1; ...
Hello, I connected my probe StLink V3 MODS via only: GND, SwClk, SwDio (CN2.pin8.13,4) for the beginning. And it rather works. Rather as once I got a strange message instead of debugging. I would like to have my probe reliable so I have found that I...
Dear experts,I'm using Cube to assign pins for my stuff (yep...) and it offers some pins with _C sufix (PC2_C, PC3_C).From the RM0433 fig.75 I gather this is something with the "analog switch" and in order to use these _C pins as AF for some device (...
Greetings everyone, I am trying to communicate with NT3H2211.My specific problem is marked red on the picture (everything else I manage to successfully send/receive). When reading data NT3H2211 wants to get " 7 bits SA and '1' " and then it will send...
We have built custom board using STM32H750VBT6.We have tried to make external loader for this MCU with w25q128Jq NOR flash of winbond.Also take one reference project from community which name is SW_H750_QSPI_Ext_LoaderKeil and modified command for NO...
Hi,There are two points I want to understand them.first one:-I want to use PSRAM with STM32F407 FSMC when I used STM32cubeMX it support Muxed PSRAM only although, STM32F407 reference manual says that it support Multiplexed or nonmultiplexed PSRAM (...
HiI have a project were i should communicate with an AD7768 ADC from my Nucleo-H743ZI2. The AD7768 is setup as SPI master and the stm32H743 is setup in SPI Receive slave only mode.There is three connections between the two devices, a clock signal, a ...
