I have setup my NUCLEO-446RE as my transmitter and it works fine, But i am not able to read any data at the Receiver i.e. the blue pill. Main things i noted are: -> The MISO pin in any stm32F4 MCU has a function of "Alternate Function push pull" with...
While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...
Hello everyone, I'm trying to sample some signals inside a timer ISR. I use all three ADC units of the mC (multiple channels in the first unit and 1 channel in each of the other two units) and I use software triggering and DMA transfer.This operation...
Hi everyoneI'm trying to get involed with the nulceo STM32u575 board developing an application that should perform synchronously a GPIOB pins output configurations over time (periodic) and set a specific analog value to each GPIO pins, So ideally I'd...
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...
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...
