I am experiencing an issue with the STM32 microcontroller used in a Battery Management System (BMS) application.Issue Details:I am using ADC to measure Temperature using NTC and voltage.When a specific GPIO pin is detected as HIGH, all ADC channel va...
Last week my debug/development environment was working. My laptop is connected to a docking station. I have a long USB-A to USB-A extension cable (15 feet) to an unpowered USB hub with 5 ports. My 'scope, power supply, DVM, and STLINK-V3MINIE are ...
Hi Team, We are working on a USB-PD sink solution to negotiate 140W (28V 5A - EPR in USBPD r1.3) and planning to use STM32G491 MCU which has an embedded UCPD interface.STM32 solutions for USB Type-C and Power Delivery page mentions that:- > STM32 UCP...
Hello!I am running the UART_Printf example on my Nucleo and the output to USART3 (default) works fine, but when I change the output to USART2 or USART6, it doesn't send data.
I need to update ST based peripherals, due to constraint of wiring and flash size, I may not be able to connect BOOT pin or make a custom bootloader on the peripherals. I am planning to implement ST's boot protocol on host side, and add a command to ...
Hello,SDRAMs are available in different speed option -5, -6 or -7. IMHO this specifies the max. SDRAM clock at CAS=3, but SDRAM can configured via CAS parameter to be used at a lower clock frequency.Alliance Memory -7 for example can be configured CA...
Hello,I use STM32F407G-DISC1 with Digilent PMOD I2S2. I have FIR filter project and after i enable sound or drasticly change frequency, volume spikes. After few seconds it becomes normal again. Why is that?Code:#include "main.h" I2S_HandleTypeDef hi2...
Hello everyoneI use an ESP32 to start a firmware update. The bootloader has been started, the esp32 writes block by block. In the end, I use the Go Commad from Bootloader Command Sets to jump into the application. My sequence.1. set BOOT0 Pin back to...
I'm trying to setup a pin configuration so that I can start making a PCB. I want to use two NAND flash ICs connected to the STM32F415ZGTx using the FSMC, setup in a way that there is a redundant backup of data and logs in the event of a failure. When...
I want to use the on-board RTC while all power (except VBAT which will be connected to a battery) is turned off to retain the clock.Is it possible to power the on-board RTC from VBAT and turn off ALL other supplies?What will happen after the other su...
