The errata suggest to "insert a dummy phase with at least two dummy cycles" when using indirect data read mode.However, according to the documentation of the dummy cycle phase (AN4760 rev 3, section 3.1.4 and figure 8 ) states that in the dummy phase...
I am using STM32F103C for mcu and SPH0645 model for microphone.When I connect only one microphone and communicate with I2S it works!then I wanted to do make stereoSo I connected two microphones one with SEL=0 and the other with SEL=1However, WS gives...
MCU : STM32H743ZTi OS : RTEMS STL: en.x-cube-classb-v2-3-0STL code integrated with RTEMS os plat form and STL test initiated from boot start area. WWDG test is working as expected until RTC and HAL_PWR_EnableBkUpAccess is disable. After enabling the ...
Hi,First time poster here, I have looked around for answers and didn't find anything that could help me. I also tried to reach out to ST but they doesn't want to help and they are throwing me to local suppliers instead.So here's the thing, the ADC is...
Can anyone help me in understanding each part of the below function?static void FLASH_Program_DoubleWord(uint32_t Address, uint64_t Data){ /* Check the parameters */ assert_param(IS_FLASH_PROGRAM_ADDRESS(Address)); /* What's this? */ /* Set PG bit */...
I have a Nucleo F103 board on which I'm playing with some code to generate a variable bit rate FSK data stream. The code seems to generate the right signal but at twice the expected frequency.I have searched these boards and found one question for ex...

F4 board (Master) with huart1 & huart2 identically configured, talking to 2 identical boards(Slaves) with the same program. huart1 works perfectly, huart2 dies after receiving from slave.Sequence:Master sends 6 chars ( 9600) using HAL_UART_Transm...
Hello,I am trying to configure TIM9 input capture to detect high-low transition on a signal connected to TIM9_CH1 pin. There is a requirement to filter out short negative pulses < 480 ns. The timer is running at 100 MHz.The configuration is straighfo...
Hi All,I have been trying to configure PC13 on the STM32G474 as a regular GPIO, but havent been successful yet.Can someone suggest what could be done ?Thanks,Manuint main(void) { LL_GPIO_InitTypeDef gpio = {0}; LL_APB2_GRP1_EnableClock(LL_APB2_GR...
