Hello,SDRAMs are available in different speed option -5, -6 or -7. IMHO this specifies the max. SDRAM clock at CAS=3, but SDRAM can configured via CAS parameter to be used at a lower clock frequency.Alliance Memory -7 for example can be configured CA...
Hello,I use STM32F407G-DISC1 with Digilent PMOD I2S2. I have FIR filter project and after i enable sound or drasticly change frequency, volume spikes. After few seconds it becomes normal again. Why is that?Code:#include "main.h" I2S_HandleTypeDef hi2...
Hello everyoneI use an ESP32 to start a firmware update. The bootloader has been started, the esp32 writes block by block. In the end, I use the Go Commad from Bootloader Command Sets to jump into the application. My sequence.1. set BOOT0 Pin back to...
I'm trying to setup a pin configuration so that I can start making a PCB. I want to use two NAND flash ICs connected to the STM32F415ZGTx using the FSMC, setup in a way that there is a redundant backup of data and logs in the event of a failure. When...
I want to use the on-board RTC while all power (except VBAT which will be connected to a battery) is turned off to retain the clock.Is it possible to power the on-board RTC from VBAT and turn off ALL other supplies?What will happen after the other su...

Hi STM,I'm working on coding I2S read/write at the same time with STM32F429IGT6.I enable I2S write with HAL_I2S_Transmit_DMA and Audio playback successfully.I could also scope the signal from the Sdout pin.However, if I enable I2S read with HAL_I2S_R...
Hello,I'm looking for detailed tutorials or lessons on the STM32H7S3L8 / STM32H7R3L8 MCU. Is it possible to purchase such tutorials or lessons? I've been using Microsoft Visual Studio with VisualGDB for quite some time now, but those MCUs are relativ...
How to cancel HAL_SPI_TransmitReceive_DMAWe are developing SPI communication devices using HAL_SPI_TransmitReceive_DMA.We would like to cancel or stop HAL_SPI_TransmitReceive_DMA even in the middle of transmission by GPIO interrupt, but we do not kno...
