I have written some codes to work with ADC Of STM32F103RE MCU, the problem is there which when I write this codes the result is 4059 for untouched and around 3585 when touched.The Codes: void ADC_DMA_init(void) { //enable DMA1 clock RCC_AHB...
Hi,I am using the STM32L496 and I have wired an SRAM to it using the FMC to read and write. I have configured it to be a 16 bit Data bus, it is a 16 bit SRAM. I am using NE1.It works well, except when I write a half-word to an odd memory location I c...
With all the distributor including arrow, digikey, I couldn't find any place that I can get this board. Is this board obsolete? or just it needs very long time to reproduce?
Hi everyone,I got a problem when i setup my can bus network. data 115200 Brate -> stm32f746vg(120 OHM //) --> CAN BUS----DEV1 --3M CABLE-- DEV2 --3M CABLE-- DEV3 (120 OHM //) DEV1,2,3 = STM32F091CCI need to explain my installation. i have 4 device...
Hi, I am using the stm32f407 card and I am developing keilda software but when I compile it does not fail but the delay does not work and I would be glad if you could help what could be the reason.

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",...
