memcpy vs split SPI transfer
Hello,I came across this question while writing a driver and I would like to ask what is your best practice in this regard. So lets say you want to interface with an chip via SPI. To perform any action, a command byte or a sequence of commands is req...

STM32F779AIY6 - What if NC pins are connected to GND?
Hello,i just received some custom boards with a STM32F779AIY6 on it.3V3 net and GND net have a short circuit when MCU is soldered, without MCU there is no short circuit.I checked everything, it should be fine.But what i just found was that the datash...
Why is my ADC reading zero for values?
My objective is to utilize ADC peripheral for reading analog signals and converting them to digital. I am using the polling method for reading ADC values. When setting up the chip configuration, I am currently using the Nucleo-H743ZI with default set...
HAL_ERROR calling HAL_TIM_PWM_Start_DMA to generate variable duty cycle PWM
Hello,i am trying to generate a fixed 800kHz PWM signal with variable duty cycle on a STM32F446RE (Nucleo-446RE). As you already might have suspected, i am intending to drive WS2812B LEDs.For this I intend to let TIM1 run at 800kHz and have TIM_CH1 r...
Variable NOR flash wait-states using the STM32F4's FSMC
Hi all,I'm planning to use an STM32F405 and its FSMC to interface with an external, parallel 16-bit NOR flash chip from Infineon/Cypress.This chip has a read page size of 32 bytes / 16 half-words.When reading a half-word that is located in a page whi...
ADC+DMA fills all the buffer when calling to HAL_ADC_ConvHalfCpltCallback()
In a stm32f303rb76, I commanded to operate ADC+DMA by setting of the ADC DMA with circular modeThe ADC I activated continuous conversion modeand DMA continuous requestAlso the analog input signal (no scan mode)In the initialization made following com...
