Hello,I am using the internal pull up for the input pins, but when read the port status using the program, it always reads 0 instead of 1. I expected it to read 1 and if make that pin grounded it shall read 0.
Hello all, I made my first "from scratch" STM32 board (in the past I always used demo boards). I cabled JTAG connector : I was able to flash and debug from CubeIDE in SWD mode with a Stlinkv2, but did not succeed in JTAG mode, don't know why but ...
Hello, I am using STM32F469BIT with W9812G6KH-6I TR SDRAM and no matter what I did, I could not write to or read from SDRAM since MCU goes into hardfault whenever i want to access SDRAM. I configured FMC according to this article. I am running SDRAM ...
I have set up a UART as receiver. I use circular buffer to copy the data in. The code pretty much works ok with one exception:If the last byte of incoming data frame is to be saved in index 0 (UARTRx[0]), the data appears at this address AFTER the bu...
usart1 connectedHercules setup utility Issue with Sending Bootloader Command on STM32According to AN3155, the 0x7F command should initialize the USART. I have ensured that I am in bootloader mode and have made the following connections:Connect th...
Hi,I am using STM32H757 in one of our projects and operating the IC to power through Internal SMPS only and made the connections as mentioned in the datasheet. The VSSSMPS was connected to VSS of the IC which is a regular practice. With this connecti...
Hi, I am using the STM32 NUCLEO-F401RE board and have already use the HAL APIs to blink the led. now I want to blink the onboard user led [LD2] using the FTDI module and want to use the USART6 for it can anyone please help and explain me in detail th...
I noticed the current draw of my STM32L011 increases after returning to stopmode from a RTC wakeup timer interrupt. The current remains higher until a reset is performed. I've narrowed it down to a minimal bit of code that reproduces the problem howe...
Hello.I need 9 channel ADC data on STM32F030 MCU.I want to read ADC CH0, ADC CH1.... ADC CH8 in order. (PA0, PA1, .... PA7, PB0) It will be a simple application. I don't need DMA. I could not change the channel in Regular Conversion. I tried to read...
Hello, We are using the STM32H747AI on a custom board and attempting to enter standby mode for power savings. The system supply is configured as "SMPS supplies LDO (no external supply)" to be able to use the boosted performance at 480MHz, but the chi...
