Hello, I programmed STM32F746 Discovery external QSPI flashed using STM32CUBE programmer with external loader option. I can able to see correct data at QSPI Flash when checking with STM32CUBE programmer.But when I am checking same address using IDE i...
One of the controller unit designed with STR912FAW47X6 processor part number, it has been obsolete..what is the replacement or equivalent to this?
I am trying to trigger conversion sequence on the ADC of an STM32H753 using the CC1 output of a timer. My goal is to start a conversion sequence every 25µs. I know that frequency of the CC1 output is correct; I am counting the events with an interrup...
I'm configuring HSI16 clock and I don't have any problem but when I switch to MSI clock at 262.144KHz, the ADC is not working.Datasheet describes that it's possible to configure the ADC from HSI clock or setting the CKMODE (0x01-0x02-0x03) to make it...
I am working on porting Mynewt RTOS on nucleo-l55ze (Cortex-m33) board,and able to build blinky and load.but led will blink only once and observed the issue that is unhandled interrupt/exception generated while context switching between main task to ...
hello, i am working with a stm32f407 discovery and a current sensor acs712 / 20A , the adc of the card hold input from 0 to 3.3v and the sensor presents an output from 0 to 5v so i have added a voltage divider with two resistors of 2.2k and 3.3k, whe...
Hello Community,I am new to ST MCUs.I want to receive multiple bytes of dat over UART. The size of the data can vary. So I want to use USART1_IRQHandler() when data is received by MCU over UART.I am able to get the interrupt correctly, But I can get ...
Hi ;I have worked with STM32F429i to generate square signal with various frequency. The value of frequency can be shown on OLED SSD1306. I configured I2C1 to connect with this display.When I connect just Rotary encoder, i can see the change of freque...
