Pwm mode stm32
How can I use PWM output pulse in my program?Normally the PWM mode for instance for TIM1 will be generated on pin PA8, but I want to use the PWM signal internally in my code. How is it applicable?

Unexpected behaviour with using STM32 QSPI over HAL
I am using the QSPI (or dual-SPI) interface of the STM32L452 to create instructions for an LED driver using the HAL. I have managed to get it to work but I have to set quite absurd configuration options for the command to make it work.Here's my initi...
How to inject your own data into the I2S line with DMA
Hi guys, as the question suggests,Mentioned by many, to fully learn how the I2S behave I must use my own valid data, so I can see what happens to it.I am having a bit of problems getting this guy to worked, I want this to implement a DMA to emulate t...
What does Data length and channel length mean both in Master and Slave mode?
Hi guys, been working on an I2S project for a while now and I am having such confusion on this bit registers "CHLEN" and "DATLEN". In Master mode it seems like CHLEN determines the frequency of the SLCK by 2 * CHLEN length * FS and data length I hav...
Resolved! STM32F446 I2S fails to work
Hi,I have setup STM32F446 MCU such that, when pressing the user blue button, it will trigger an external interrupt. Inside the interrupt routine, it contains the I2S receive function:void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ int16_t audio_buff...
Resolved! Hello All I am implementing a simple application using STM32F205 and UART. I have enabled UART as global interrupt. I want the program to detect \r or \n in a string that is received continuously.
I wish to print "String recieved" if /r or /n is detecetd otherwise i wish to print "Error" .The problem is after detecting the first string i receive an output "String Received" After which i also receive error message. I have doubt if i have implem...
Is it just a lack of consistency in HAL drivers?
I have my clock configured to external crystal 80MHz but accidentally I connected another board without crystal. STM32 started OK using internal oscillator at 4 MHz - HAL_Delay works fine, UART works fine but I2C is very slow. It looks like I2C HAL l...
How much time is required ARM controller to attend the ISR ???
I know this is a very basic question, but I want to know to decide whether the polling method is better or the interrupt method is better for time-critical applications.Kindly help me ...
