Hi,I am currently developing with the STM32F769I-DISC1 development kit and get audio output via the CN7 Line Out connector when setting the initialisation to OUTPUT_DEVICE_HEADPHONE in the sample example as below: if(0 != audio_drv->Init(AUDIO_I2C_AD...
I'm working on a low power driver for our project and want to put the mcu into sleep mode to be woken up by a timer. The mcu enters the Sleep mode but does not exit from the same. Since I have the Seggar J-link connected to over a JTAG port for debug...
I am using the STM32F407 discovery board and Wolfson pi audio interface. I have a problem in analysing sample values received from MEMS microphone.I wanted to plot the data sensed by the MEMS microphone, which is just sensing the surrounding environm...
Hi,I use I2C like this uint16_t I2cAddrTemp = 0x90; uint8_t I2cWritedata = 0x00; uint8_t I2cReaddata = 0xFF; uint8_t read_i2c_temp(void) { hi2c1_status = HAL_I2C_Master_Transmit(&hi2c1, I2cAddrTemp, &I2cWritedata, 1, 1000); //PRINTF("I2c = %02X",...

Hi all,I'm having some trouble getting DMA to service sequential uses of I2C+DMA transactions.I can have the I2C+DMA initialize our demodulator, which involves some 12,000 reads and writes. (So, I2C+DMA works *very, very well* when it works.) I ca...
Posted on March 29, 2018 at 04:32I am trying to get the STM407VET to communicate to an SD Card using the SDIO interface and drivers. Code base was generated from CubeMX and Eclipse is the IDE. Debugging with Open OCD. Hardware is custom. I have trac...
Hello,I have a little confusion regarding FMC memory map. I hope someone can help me with it.Accoring to reference (stm32h743) FMC external memories are mapped as following:0x6C000000 -0x6FFFFFFF FMC NOR/PSRAM/SRAM 4 Bank1 (or remap of FMC SDRAM Ban...
Hi,I am running into a strange problem, I am using strncpy function to copy one array into another. If i include this in my code i get a Hard fault DEBUG_VT . I have read quite few article on hard faults and how to track them down but this one that i...
