SPI communication by DMA and SPI communication by BDMAWe would like to confirm the difference between SPI communication by DMA and SPI communication by BDMA.for some reason, the MISO data output (slave output) is delayed by 2 to 3 CLK in SPI communic...
There is no clear information in the reference manual about port pin configuration locking one by one. For example (desired code): void SomeFunction() { // locking pin configuration one by one LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_0); LL_GPIO_Lock...
Hi there,I'm working on a project with the STM32U5. This MCU comes with both a SPI and a OCTOSPI peripheral.The SPI peripheral supports a setting called MasterInterDataIdleness - in the reference manual it's shown as "master Inter-Data Idleness", whi...
Issue with SPI DMA Transmission Starting from Random Index Instead of Array Start (Circular Mode) (STM32L562VET6)I am working with an STM32L562VET6 and have a 2D array DATA defined as follows: uint8_t DATA[NOS][3] = {}; Here, NOS = 20000, and each ro...
I am writing an LPTIM driver without HAL or LL drivers on the B-L072Z-LRWAN1 board. I have been getting a number of odd behaviours here that I am hoping someone here can shed some light on.1) cannot enable continuous start -bit 2 of the CR r...
Hello, In my application USB Device, on successful enumeration, BIT13 "USB_OTG_GINTSTS_ENUMDNE"of OTG core interrupt register (OTG_GINTSTS) turns High.As per USB2.0, if my USB Device in its Device Descriptor demands for higher power than what externa...
I am using the STM32H562VGT6 and IAR Workbench. I have set up a 4kHz interrupt with LPTIM3 and started transmitting 32 bytes of data using HAL_SPI_Transmit_DMA. If I break and resume execution after starting the timer interrupt, the SP becomes 0xffff...
I'm trying to get the ethernet initialization work. I am currently dealing with MX_ETH_Init(); failing in error handler as the software reset is not happening with the phy driver. I believe my clocks are not configured properly as per manual : As ...
Hi All!Following are the proper codes for read and write the password in Micron MT25QL256ABA READ PASSWORD 27hWRITE PASSWORD 28hWrite Enable is executed before to write password using 28H, I wait for the flash to be ready by reading the FLAG STATUS r...
Hi STM32 Team,I am working on implementing a USB Mass Storage Class (MSC) application on the Nucleo-F439ZI development board. My objective is to use the Fat Fs file system to read/write data from/to a USB flash drive.I need example code for that. Fo...
