Have someone working program for demonstrating USART with interrupts for STM32L152VB?
I written a code for uart.Transmission working properly, but when i using interrupt, then no output shown on docklight screen

Does STM32 MCUs support runtime change of GPIO mapping between alternative functions?
Hi,We would like to make a design where we have several LEDs grouped to banks (3 LEDs per bank and 3 banks thus 9 LEDs total)In each bank of 3 LEDs, only one of the LEDs would be driven with PWM (brigthness control) and other would be either ON / OFF...
I am a totally new in code also totally new in use STM32F407 and now i doing the assignment for implementation of a state machine that will be driven by the joystick input.
The question including in the 1st picture i want to ask that is that any material allow me to learn for coding and solve assignment question.2nd picture whole part of board3rd picture is STM32F4074th picture is the part of the joystickThis is my curr...
Resolved! Can I set the system clock identically with the maximum?
Hello, everyone.I looked at the difference between VOS0 and VOS3 through the datasheet to set the clock speed of STM32H753 to a suitable value.I am currently setting the system clock at 200 MHz and the FDCAN input clock at 50 MHz.When set to VOS3, th...
Understand how interrupts work
Hi all,I'm trying to figure out how to handle an interrupt. In particular I would like to handle an interrupt without using the HAL library. I want to handle the uart interrupt in reception: RXNEIE enabled: when the data is received an interrupt occo...
32L0538Discovery ADC
Hello,When trying to use ADC, I ran into a problem that I don't really understand.If I try to use ADC through the PA4 pin, the values read fine and are correct.However, when I try to use any of the other pins for ADC, none of them seem to read the co...
Reading pin state with LabView
I'm using an STM32L476RG and making a LabView program to display sensor data. When a pin is set to HIGH I want to take a data sample and store it in an array in LabView. I am having trouble detecting the state of my 'sample' pin while continuously st...
UART and STOP 2 Low Power mode [stm32L496VG]
Hi,UART stops transmitting (both IT and polling modes) after entering and exiting from STOP 2 mode. Although I'm renabling the UART when I'm exiting STOP 2 I don't see the data received on the other side.When I'm connected to MCU via JTAG everything ...
How to count input pulses without waking from sleep mode.
Hi, I have an STM32L072 micro. I need to count the transitions on two IO pins.I would like to do it while the MCU is in sleep mode and periodically wake to process the results.In this MCU there is only one LPTIMer . Is it possible to configure the ot...
Has anyone been able to get the camera module on the STM32 469I-EVAL kit working. I made sure to disconnect J3 like the datasheet says, and have probed the crystal output on the camera to make sure it's receiving power.
The rest of the signals aren't easily accessible, but I've been trying to run the example camera project and I'm just seeing a blank white screen. After some debugging in the software, I found that it's getting hung up waiting for the first valid fra...
