Using NUCLEO F756ZG & STM Cube IDE I am trying to setup & enable interrupt for TIM4 The compiler is not happy with these 4 lines of code TIM4->ARR=5000; NVIC_SetVector(TIM4_IRQn, (uint32_t)&TIM4_IRQHandler); NVIC_SetPriority(TIM4_IRQn,0); NVIC_Enab...
I am working on a pathological voice assessor device, using the STM32H747-DISCO development board. Currently focusing on sending a signal from the DSP to PC - there is also a separate connection for debugging from my Macbook which is plugged in to th...
I am trying to receive audio data from an I2S microphone (https://www.adafruit.com/product/3421) using my STM32L476RG board and its Serial Audio Interface (SAI). I'm using cubeIDE and I have the SAI set up as in the pictures below, however I am not s...
Hello there,I know this is an old debate but since we are into production of a device using STM32G030F6 chips, we wanted to make sure the cheapest options are used while keeping them "original".The minimum price for the aforementioned MCU on ST e-sto...
Hi, Can I control the level of a GPIO Pin in software, if the GPIO Pin is in an Alternative function mode ? For example, I have an application where I switch a MOSFET in Software, but I would like to use the Hardware or internal Silicon, and Softwa...
UART transmitter transmits wrong ascii value to my pc. what is the problem in my code..??I put a charecter in Data Register, but serial terminal show another ascii code.My IDE is KeiluVision5. the code is in below..... #include<stdint.h>#include<std...
Hello.Using "ITEMIS Create" I've designed this simple statechart diagram to figure out the working principles of sleep mode. The diagram is shown below:The program should work like this: Device boots up, starts a timer, that has a period of 2 seconds...
Hi there, I want to setup the NUCLEO-H755ZI-Q to run just the microcontroller alongside a VL53L4CX ToF Sensor, I am currently having troubles, can anyone help? I am having troubles configuring the controller and printing values as UART is not configu...
STM32L051K8U6 The code always gets stuck hereThis situation is likely due to the slave not responding to the address, but with the same hardware, using software-simulated I2C communication works perfectly fine.I have already checked, the slave addres...
In the thread https://community.st.com/t5/stm32-mcus-embedded-software/why-does-my-tx-only-software-3-mbaud-uart-sometimes-send-strange/td-p/218077/page/2 I learned that "DSB" is a good way to waste a clock cycle in STM32F769. Now, what's a good way ...
