Hello everyone.I'm interfacing my STM32F745IET6 (master) with an SPI device.I'm using SPI1 interface running at 50 MHz, I was wondering if there's some "rule of thumb" to calculate time needed (in terms of clock cycles) to write n bits over the bus. ...
I'm developing a custom board with an STM32U5 MCU and a MX25UM51245 NOR flash memory. I'm building upon this example, which works flawlessly, but I don't want to format the memory every time the code runs. To achieve this, I disabled the Driver calls...
Hello,I want to transfer data between NVIDIA Jetson Nano (Master) and STM32 (Slave) using SPI. On the master side, I am using spidev python library. On the slave side, I am coding using registers (without using HAL).I want to send and receive data co...
Hello,I am working with a STM32F446ZET6 and using it as an SPI slave.I use the function HAL_SPI_Transmit_Receive_IT function to receive 4 bytes of data.It used to work properly in our conception, for example when the master sends 0x12, 0x34, 0x56, 0x...
Hi all,I'm facing a problem with the implementation of a double Own address on a STM32F030K6T6 uC. the project is already working but with only 1 Own address on OAR1 (code 42 hex), now I want to update the project to enable the reception of another c...
I have added a Touch screen library and I am unable to integrate it into Touchgfx Project that is opened inside Stm32IDE -I am getting File not found errorWhat I have done so far-Added the file using Properties ->c/c++ general-> path and symbols ->In...
Hi i m learning to configure GPIO using registers, and come across the following code, can anyone kindly help to advise the following? what does the whole sentence do? what does the (volatile....) means, what does GPIO_OUT_DATA(0) does and what does ...
Hi I've been searching for some info about these two MCUs and I need some clarifications.1. What is the difference between STM32U585RIT6 and STM32U585RIT6Q?2. On page 150 of DS13086, STM32U585xx datasheet, regarding power supply scheme, I can see the...
Currently i am using USB peripheral for communication (CDC) with STM32F070CBT6 microcontroller. For generating 48MHz clock, i am using internal oscillator as a source for internal PLL circuit. I have to send certain data to STM32 (for save it to exte...
Hi, I am trying to use DMA in my project for SPI and noticed there are 2 type definitions as below:- SPI_HandleTypeDef hspi1; DMA_HandleTypeDef hdma_spi1_tx; Which one do I need to use for SPI transmission as I am having problems using 'hspi1' as b...
