I am trying to use one STM32M4 as TX, and another STM32M4 as RX,but RX can't receive the correct i2s data that TX transmits.TX transmits 16bits data by HAL_I2S_Transmit_IT(&hi2s2, i2s_dummy_buffer, 16);RX receives 16bits data by HAL_I2S_Receive_DMA(&...
HelloMy current requirement is to generate an FSK waveform with two frequencies around 3-5 MHz, a rate of about 700K, and output a square wave using PWM. The method involves switching frequencies by updating ARR and CCR using two timers—one for PWM o...
Hi. I designed a stm32 board an am trying to program it with a stm32 development board. i am having issues with programming it. This is my board design and my programming setup. I have connected the stm32f4 to my laptop to program it and the Integrat...
Hi all,I’m currently working on a wireless mesh network project using the S2868A2 expansion board with the NUCLEO-U083RC, operating in the 868 MHz ISM band.This system is designed to be low-power, which is why I’ve selected the Sniff Mode (LDCR) feat...
Hello everyone,I am doing a project of sampling a PWM signal and reproduce it dynamically using the HRTIM. The following code:uint16_t oldPer = 0, oldDur = 0, update = 0;uint16_t newPeriod = 0;uint16_t newDuration = 0; void HAL_TIM_IC_CaptureCallback...
Hello,maybe this is bit off-topic, but does anybody know if it is possible to suspend an ERASE operation and write to another (previously erased) sector?I want to save a page in flash in case of a power outage and want to interrupt a probably ongoing...
i use stm32h750 as a decoder to translate use audio data into i2s 16bits 48khz data.however, when i use usb_otg_fs, everything works properly,but when i use the same configration and only switch to usb_otg_hs,some problem has occured. i use usb3300-e...
Hello,I'm trying to figure out the max. reliable clock frequency for NOR flash connected via SPI or QSPI interface.I've read here or here that there are custom board and evaluation board designs which are reading data at single transfer rate up to 1...
I’m working with an STM32H7R7I8 MCU and an external W25Q128JV QSPI Flash connected to XSPI2 --NCS1 -- Port1.The Flash memory is wired correctly (pins verified) and the Chip Select line (NCS1) idles high after power-up (I've used 10k pull up resistor ...
Split from this thread. Thank you for your previous responses and guidance. We are now planning to move to the STM32H750XBH6 (BGA package) with a 32-bit SDRAM (IS42S32400J-6TLSDRAM ) interface in our custom board design.Our project uses a 12.1-inch d...
