I'm designing a custom PCB using an STM32F103 microcontroller to control a triac-based light dimmer. The firing angle for the triac is determined by reading the voltage from the potentiometer.The potentiometer output is routed through a header and th...
I'm trying unsuccessfully to erase a 4K sector at 0x73ff0000 using STM32CubeIDE code, but the STM32CubeProgrammer works fine. I've tried using BSP_OSPI_NOR_Erase_Block() and MX25LM51245G_BlockErase() with no luck. My code base is the HTTP_IOT_WebSer...
I wanted to do a full chip erase using STM32Programmer (I am trying to debug a custom bootloader) but kept getting the error "Mass erase operation failed. Please verify flash protection".I sent the following option byte screenshot to ChatGPT....Chat...
Hi, I designed the us and ms delay functions using timer 2 and 4. Initially in the PLL source, I was using HSI, but it had some errors, so I switched it to HSE. I was using my delay function to control the DAC output, but when I switched to HSE, all...
Hello everyone, I'm using two STM32H503 boards. One is programmed as an I3C controller, the other as an I3C target, and I'm trying to achieve the following sequence on the I3C bus: IBI from target -> Repeated Start -> Private Read I find two things...
Hello, I am struggling to use the following ST library for a project I am working on, I am using an stm32u5 with an MX25UM51245G NOR chip connected to the OSPI1 bus. The library provided is setup to use XSPI_HandleTypeDef, Can this library be used w...
标准时间（标准时间)的标签产地和芯片产地不一样,请问这个是否正常 Translation: The label on this device (Standard Time Clock) indicates different countries of origin for the product and the chip. Is this normal? Edited by ST moderator. In next time please use English as this is an i...
I'm reading the RM0008 Reference manual.....I can't find a description of the registers and events associated with the entry point of Vector table for USB_HP_CAN_TX and USB_LP_CAN_RX0....What does it mean USB High Priority and USB Low Priority ?How d...
Hello, I am working on STM32U5G7VJT6 with FDCAN1 peripheral.In CubeMX I configured 8 Extended Filters, and in my code I set them as dual filters. That gives me a total of 16 CAN IDs that can be allowed by hardware. Now my application requires filteri...
I am using the DAC on the NUCLEO-L433RC-P board for development and have also designed a custom PCB using the STM32L433.The DAC is used for audio voice prompts (12 bit, 44.1kHz stored in external flash) and fed into an audio amplifier (TI LM48100Q).H...
