Hello together,I'm a little bit confused by the NVIC and EXTI description in the RM0503.The NVIC vector table says the RTC / TAMP interrupts are combined EXTI lines 19 & 21 (on page 302).But when looking at the EXTI line connections table (on page 30...
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...
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...
Hello,I am working on an experiment to synchronize multiple sensors using the I3C protocol and would like some guidance. I am following the DT0155 document. My setup includes:1. Nucleo-F401RE2. X-NUCLEO-IKS4A13. STEVAL-MKI227KA4. MEMS Studio software...
