I’m working on a program to transmit data over SPI1 and SPI2 using DMA. For output I only use each peripheral’s CLK and MOSI lines. SPI1 and SPI2 differ only in the exact data being sent—their configurations and the number of bytes are identical. Als...
I am looking at a project where I would typically use an SBC, but wondering if ST has enough usb host support to accomplish this with existing usb stack software. If so what would be recommended models? Will be used as a usb host only (role change...
Hello everyone, I'm currently working on an SPI bus on an STM32U031C6 + S2LP. I'd like to use my SPI with DMA mode. The SPI bus I used previously worked on this board. As this is my first time using DMA, I'm simply trying to send data without necessa...
Hi,I’m using EDataBank_1 on an STM32 device to store user data after a power cycle. I based my code on the EraseProgram example and made these changes:What I did:Enabled FlashPeripheral and set EDataBank_1 size = 2On first boot, I do:Init → Erase → P...
Hi ST expertI'm ready to use STM32H723 now. Vcores can use internal LDOs or external power supplies via Vcap pins. If you use an external power supply, what is the current of the power supply, I see that there is only Idd in the datasheet.Thanks
The errata for the STM32U575 series includes the following: We would like to use the first option of the 2 listed workarounds (the one that does NOT require disabling and reenabling the ICACHE). Does ST have any implementation examples of this worka...
Maybe it is not supposed to be used like this:Regular receive interrupt handler and using LL_USART_TransmitData8 function.Then sending a larger configuration file using HAL_UART_Transmit_DMA on demand.This leads to these flaws:1. HAL_UART_Transmit_DM...
Hello.. can anyone advise where to download the F767 Nucleo BOM list?
Peripheral: QSPIBug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for athreshold leve...
Does HAL_RTC_AlarmAEventCallback work if the the MCU is in shutdown ?I am using RTC wake-up timer for wake/shutdown cyclingRTC alarm for shutdown trigger via HAL_RTC_AlarmAEventCallbackBut:RTC Alarm A interrupt never fires if the MCU is in Shutdown m...
