The datasheet says that power must be supplied on this pin if USB is to be used. It must also be the last power supply to be energized and the first to be removed.If my design does *not* use USB. Can I tie this pin to VSS and call it a day?I want to ...
I have an STM32-L4P5DK connected to an external ADC, with SPI2 configured to read ADC samples on every falling edge of the DRDY signal. The DMA1 configuration is as follows:DMA1 CHANNEL1: DMA_GENERATOR0DMA1 CHANNEL2: SPI2_TXDMA1 CHANNEL3: SPI2_RXThe...
Hi Everyone, I have a project utilizing a STM32G030F6P6 with a 32.768kHz crystal and the LSE to source the RTC clock. It is exhibiting 2% clock error (which is huge!) over a 10 minute period despite using a 20ppm crystal. I am measuring this error by...
I need to generate a pulse which is activated high immediately by rising/falling input signal around 100Hz with varied width. I have tried One Pulse Mode and Gated Mode on STM32f334R8T6 so far but none of them were successful. Even I tried on HRTIM,...
Hii, I am trying to interface ADC module cs5532 using SPI communication with STM32H563ZIT6 on NucleoH563zi board. I have also completed pin configuration on .ioc file and successfully generated a code. But SPI communication is not initializing. I h...
Hi, I'm working on ADC1, on a STM32U5 (on a Nucleo board). In reference manual (RM0456) § 33.4.13 "Channel-wise programmable sampling time" we can read how to compute the total conversion time Tconv. The example is given for SMP = 5 ADC clock, at 55...
I'm using stm32h5-nucleo144-board to develop USB (HID or CDC_ACM) application, I start with STM32Cube_FW_H5_V1.3.0 code by directory STM32Cube_FW_H5_V1.3.0\Projects\NUCLEO-H563ZI\Applications\USBX\Ux_Device_HID_Standalone.firstly, when I download th...
How to trigger different ADC channels for conversion at different frequency?
Hi guys,I am wondering, if there is any “real” benefit in using the HAL over the LL for simple peripherals like GPIO, ADCs or Timers.So far it looked to me like the HAL does not make the user code more compact or readable. Instead, it just gets more ...
Hi i plan new design and require activate for example on PA3 ADC1_IN4 and same time COMP2_INP.Is this possible and if yes how sequence to setup HAL LL or direct?EDIT: Renamed from more AF ... only one AF poss.
