I want to play audio on STM32F4 Discovery board. Audio is stored in SD card which connected by SDIO. On discovery board, I see below connections.I2S3_SCK -- PC10 -- (SCLK) CS43L22I2S3_SD -- PC12 -- (SDIN) CS43L22but PC10 & PC12 are also connected to...
EXPLAIN ABOUT SECURE FLASH MEMORY
HelloI'm using Abracon 25MHz( ABM11W) crystal for HSE clock on STM32H750.CL1 and CL2 are set to 12pF after some calculations. And it works on the prototype.Question is regarding the resistor do reduce/control driving level to this crystal. I have bee...
I have enabled USB Device FS and successfully use it as a virtual com port.I now need to determine the best way to send messages from master to slave over this port, and how I will handle potentially corrupted data, timeouts, and how enabling CRC wil...
Dear ST,I try to use SPI1 in full-duplex slave mode with hardware NSS and interrupts.Interrupts work fine, the only problem is that data is all 0After connecting the logic analyzer I noticed that the CS and SCK signals are ok but the MOSI and MISO ar...
Hello,I'm trying to use the I2S transceiver on a STM32H7.I did a first simple experiment using the HAL function: HAL_I2S_Receive_DMAI use a basic loop in the main:while (1){ if (i2s_bsy == 0) { i2s_bsy = 1; i2s_status = HAL_I2S_Receive_DMA(&hi...
OK so here is the finale of the trilogy (first two installments here and here).If SDA is pulled low externally *after* I2C is enabled by setting I2C_CR1.PE, I2C_SR.BSY goes high; and if under that condition master communication is started, there's no...
i am using IMU ICM-42688-P sensor communicating with stm32 GOB1CET6N board using spi protocol. but, i am not able to read WHO_AM_I Value for more than 2MHz frequency. i have tried all settings but nothing is working. datasheet of sensor says SPI work...
Hello all, I want to ask you that is any microcontroller in STM32 series which gives the 5V digital output .. I'm using STM32F746ZGT6, that gives 3.3V as digital output.. I want 5V digital output from microcontroller.. if somebody know then please su...
I'm using a Nucleo-H563ZI in non-secure mode.When I access the FLASHSIZE_BASE address:#define FLASHSIZE_BASE (0x08FFF80CUL) /*!< Flash size data register base address */I get a hard fault (16 or 32 bit access).In the debugger the memory dum...
