Hi there,I have problems when I m using the FDCAN controller. I m using the NUcleo STM32h745ZI with a shield with a can controller on in CLASSICAL CAN mode (NO FDCAN).If a run an example in the HAL_Driver folder it works ( @1MHz Fdcan kern freq = 40M...
I'm using PB14, TIM15_CH1 for my PWM signal. Since it's TT_a I/O structure 3.6V tolerant.
Hello,I'm working on a nucleo-f401re board, with HAL library.I'm trying sampling a signal and measure its duration, to do it I'm triyng to use the TIM2 of my board to detect rising and falling edges of the start signal, and this works fine.I would al...
Does anyone know how you're supposed to get a clock speed of 480Mhz when the lowest PLLP1 divider is 2, and the max "wide" VCO freq (Input source / DIVM1 * DIVN1) is 836Mhz? Ie This seems to cap the max speed at 418Mhz. Of note, Cube doesn't complain...
hi I used the code in this link https://github.com/MYaqoobEmbedded/STM32-Tutorials/tree/master/Tutorial%2024%20-%20NRF24L01%20Radio%20Transceiverfor communicating with nrf24l01 with stm32 and it worked fine but I wanted to rewrite it in register leve...
Could anyone tell me why the same "CPU power state: CPU in Run mode" and "Domainx power state: DRun mode" have two different GPIO states which are on the page 300 of RM0433?
I've just been caught by this very same issue:https://community.st.com/s/question/0D50X00009XkaBXSAZ/rm0090-usart-minimum-attainable-baudrateAt this place I'd like to ask ST to reconsider baudrates generation for both UART and SPI - please connect th...
I know that I will need to use UART. but I don't know how to see the data sent and received and on what terminal will I be able to see all this.
Hi.I thought this question is more suited to education.I have been working on a STM32F091 C++ project just to get an idea code size, and I noticed that the size of the binary is huge even when optimisation is set to (-Os). I think its because the co...
I have an issue with SPI in bidirectional mode (MOSI, CLK and CS). I have a device which I need to write to and from. When I have to write to an adress in the slave device, it works perfectly: reg=0x04; CS_DRIVER_LOW c=HAL_SPI_Transmit_DMA(&hspi2,...
