Hello, I am new to STM32 and I am trying to generate PWM signal of 10 KHZ and 50% duty cycle and i am not able to achive it and I am using STM32L476VG DISCO board and for reference I have attached the code. Thank you
/*CODE to generate PWM signal of 50%*/#include "stm32l476xx.h"#include "pwm.h"void pwm_init(void){ /*RCC configuration*/ RCC->AHB2ENR|=RCC_AHB2ENR_GPIOEEN;//ENABLE GPIOE RCC->APB2ENR|=RCC_APB2ENR_TIM1EN;// ENABLE CLOCK ACCESS TO TIM1 //RCC->APB1ENR1|...
DMA stay in busy state when using HAL_I2C_Slave_Receive_DMA
Hello,I'm working on 2 NUCLEO-F767ZI Demo Board.I'm using STM32CubeMX with last firmware package to generate the code and STM32CubeIDE to modify it and debug it.One of the board is used as an I2C Master, the other as I2C Slave. Every thing work fine ...
Resolved! I need to use PG10-NRST as a GPIO. So I check the Reference manual to find out how to do it. I find that it can be done if I modify the field NRST_MODE to 2 and I really do this. But it doesn't work.The mcu still reset when PG10-NRST comes a low level.
Here is my code in main() to config field NRST_MODE: HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); gFlashOBST.OptionType = OPTIONBYTE_USER; gFlashOBST.USERType = OB_USER_NRST_MODE; gFlashOBST.USERConfig = FLASH_OPTR_NRST_MODE_1; HAL_FLASHEx_OBProgram(&...
FDCAN2 4 times slower than FDCAN1 on STM32G491
I was finally able to find the correct settings to configure my CAN peripherals with correct bitrate after tweaking for a while in STM32CubeMX. The settings that work do not make sense. FDCAN2 is 4 times slower so I had to make clock divider for FDCA...
Resolved! PWM Output Not Generating Waveform for STM32F429ZI
Hi everyone, I'm just trying to test and verify some clock frequencies for a PWM waveform are correct. I used CubeMX to generate some code that has set the clock frequency of the MCU to 72 mHz and I am trying to achieve a 20 kHz PWM frequency. I enab...
Sharable D1 SRAMs in the more recent H7 chips
As per RM0468, STM32H72x and STM32H73x chips have 192 KB of SRAM in the D1 domain that is 'sharable' between ITCM and AXI SRAM, ie. it can be allocated as ITCM or AXI SRAM with 64KB granularity,It is known that SRAMs in D1 (or any other domain for th...
STM32L151RC6, I'm not clear what TIMx_IN1, TIMx_IN2, TIMx_IN3 and TIMx_IN3 alternate functions 14 (CPRI) are
Working on a STM32L151RC6, I'm not clear what TIMx_IN1, TIMx_IN2, TIMx_IN3 and TIMx_IN3 are (datasheet, alternate function 14, CPRI).Belongs to Analog Comparators or Timers?As far as I figured out, if I select AFIO14, the GPIO pad will be connected t...
