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,...

Hello,I'm trying to write a PWM input capture function(I only need the on time. not the frq and duty cycle) and I see that it takes two channels of a timer. I need to use all four channels, Is it possible?Thanks
