hi i use two spi and connect together spi 1 send(Full D Master) and 2 receive(Full D slave ) all in dmaif i change send buffer, in receive first array not change. it was first init that send dma uint8_t TXBuf[]={0,1,2,3,4,5,6,7,8,9}; uint8_t RXBuf[10...
The STM32H7 reference manual revision 6 gives the FastSinc response as:However this seems to make no sense. The first part is a normal sinc^2 filter, but the second part describes an impulse + delayed impulse, which results in a quite strange frequen...
Hi All,I config UART on interrupt, after receving data on UART simple sending data at that time hard fault occur.UART enabling code MX_GPIO_Init(); MX_DMA_Init(); MX_USART2_UART_Init(); MX_RTC_Init(); MX_SPI3_Init(); MX_TIM2_Init(); MX_TI...
Can i transfer files from my pc to stm board memory using this config of usb memory device , else i should configure it as a host please let me know this. thanks in advance.
I want to know if is possible power OFF the SRAM1 (256kb) and keep only SRAM2 (64kb) ON, during Run Mode. I know that is possible power OFF SRAM2 in Standby-Mode with the register PWR_CR3 (bit RRS). - Reference Manual pag. 187
I want to FDCAN LOOPBACK using STM32G474RE. but i'm not find example. help me please. I don't have much time left. :(
I couldn't find this mentioned in another thread, most discussion was based around LSE vs HSE & LSI. Basically, I'm wondering if we used an external 32.768 kHz clock with the STM setup in bypass mode, whether that clock could be used to maintain RTC ...
Hi I want to communicate with a device that uses SPI, I want to grab data from this device but when it transmits a byte waits for an acknowledgment signal which is a positive pulse with 2us lent. So I should wait until it sends 1 byte of data, store ...
the debugger of IAR EARM V8 has lots of bugs in tracking C codes sentences, has anybody experienced it and find a solution?V7 is pretty stable but no support for many recent ST MCUs, I think F7(not all of them), H7, L4+any idea to add these MCU as pa...
