If I'm interested in the availability of STM32L4 chips that come in a LQFP64 package and also has a DFSDM interface, I use the "View all STM32L4 series products" and select the appropriate filters. I then get a list of 17 different micro variations. ...
Hi guys,I would like to know how can I read PWM (duty cycle) generated from stm32?And how I can read Pwm generated from 1 stm32 send to another stm32?Sorry my bad englishTy
Hi,I want to do SPI transfer every 1ms without wakeing up CPU.In one SPI transfer, I want to send 10 Half words.It was possible to send SPI every 1ms with dma.But I can transfer only a half word in one transfer. What should I do ?Best regards.(Below ...
Have several boards with problems keeping time accurately. We calibrate each board in factory test, but some boards have very large errors in the 1 Hz calibration signal and very jittery frequency readings. To make it more interesting, when there i...
It's not clear from the datasheet under what conditions pins are 5V tolerant, or what the pins can tolerate when configured as output. I'd like to know 2 things:What is the max voltage on a pin (PB0) configured as open drain? I want to have it pulled...
I'm a bit confused what ISR==0 means in a DMA IRQ handler. I can skip it but wonder if something is configured incorrectly. Is "ISR==0" an expected and valid case or do I need to delve into settings? No error code is set, I am funneling all BDMA ISRs...
Hey everyone.In my project, I want to reserve some flash sectors to write data that I don't want erased when flashing new code on my processor.So I changed the .ld files to reserve my memory as follow :M7 files :STM32H755ZITX_FLASH.ld and STM32H755ZI...
I'm using the HAL_UART_Receive_IT function on stm32f303re to recieve data. After each use I want to delete the content of the receive buffer so that the next data that will arrive will start at the first index of the array. Is there a function to del...
I'm using MSIS at 24 MHz for everything, like this: SET_BIT(RCC->CR, RCC_CR_MSISON); while (0 == (RCC->CR & RCC_CR_MSISRDY)); SET_BIT(RCC->ICSCR1, RCC_ICSCR1_MSIRGSEL); MODIFY_REG(RCC->ICSCR1, RCC_ICSCR1_MSISRANGE, RCC_ICSCR1_MSISRANGE...
