I am using STM32H7 family of microcontroller as SPI Master Transmit device which needs to talk to 4 SPI slave devices receive only which are also all STM32H7 MCU's. Both master and slave are configured for software slave management. The confusion is ...
How can I avoid this?
Dear all,I am in difficulty to adjust Timer 3. Let me explain with examples:Internal Clock is 72 MHz and it is used for also Timer 3 as an input clock.1- When PSC: 36 and ARR: 124 it should generate an interrupt every 62,5 us (we can assume it genera...
Hi people.I have a circuit which must enables an LDO by pressing a button which applies 4.2~3.7V to EN pin of regulator. after enabling LDO, MCU (which is from F0 series) powers on and takes control of LDO EN pin by applying a HIGH output on EN pin w...
Hello!I am trying to generate COMP2 interrupt on the rising edge on Input[+] of COMP2.Input[-] is conected to ground and Input[+] is connected to pull down resistor.What is strange that interrupt is generated only when Input[+] is connected to ground...

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...
