Hello everyone,I'm observing inconsistent FLASH ACR EMPTY flag behavior on two STM32G070RB chips (DEV_ID 0x6460) after a full chip erase by using STM32CubeProgrammer]Observed behavior:STM32G070RB (REV_ID 0x2000): After full erase, FLASH_ACR EMPTY fla...
Hello All,I am very worried about this as time is short.I am attempting to get my STM32L073RZ into low power mode using STM32CubeIDE version 19, and it wakes as soon as it sleeps. I am wondering if this is a problem with my code, or possibly an issue...
Hi everyone,I'm developing a bare-metal application with an STM32H725RG MCU using STM32CubeIDE (including HAL and code generation).I want to use the IWDG1 for reliability purposes, but for some reason, it seems to not work for me at all - upon startu...
Hello Friends,Most STM32 based Evolution / Development Board has Crystal 32.768 Khz and Boot switch connected. In my Custom design board , I do not need RTC Function and Bootloader to load.8 Mhz Crystal is used for Master Clock. Can I remove 32.768 k...
Hi, IM USING EXTERNAL CRYSTAL NX2016SA-25M-STD-CZS-1 IN HSE 25MHZ AND LOAD CAPACITOR 10pF ,BUT I'm TRY TO USE EXTERNAL CRYSTAL IT CAN'T ENABLE . LSE 32.768kHZ ALSO NOT WORK ,HOW TO ENABLE THIS EXTERNAL CRYSTALS .MY CONTROLLER PARTNUMER IS STM32H753V...
Hello All, I am trying to do a loopback test between 2 i2c's on the same board, using bare metal coding and interrupts, and the clk is HSI, 16MHz. How the i2c i configured as slave is failing to acknowledge the address sent by master i2c.Here is a zi...
Hello everyone,I have designed a custom PCB using STM32F103RBT6 and I’m facing a serious issue:The MCU is not getting detected by the programmer.Symptom:When connecting via SWDIO, SWCLK, 3.3 V, and GND, both STM32CubeProgrammer and ST‑Link Utility fa...
Hi there,I tried to add support for a PDM microphone, but so far I could only get 0's from DMA. Somehow, the polling method (HAL_SAI_Receive) did return non-zero values. Here is how I set up the SAI and DMA:I did so by modifying our project's existin...
I'm trying to set up CAN communication between two STM32F4 boards using CJMCU-230 transceivers, but I'm not receiving any messages. Here's a full breakdown of the setup and what I've tried:Hardware Setup:MCU: STM32F4 Discovery (hcan1)Transceiver: CJM...
Hi all,I am working on a project involving reading from the external AD7768. I've tested to get data out of it using and EXTI and Interrupt based SPI receives, but that was too slow to capture the message, so I'm trying to get it to work with DMA.The...
