Hi,I'm following RM0390 reference manual's PWM input mode example for calculating frequency and duty cycle for incoming PWM signal. Basically I'm using TIM1's CC1 for capturing rising edges and CC2 for capturing falling edges. The question is that is...
I am looking at the STM32H7 reference manual and STM32H745 code examples to determine how to transfer and signal new information between the cores. Currently I see two possibilities: Shared memory and a hardware semaphore/interrupt or shared memory a...
Hi all! I'm fighting witn CMSIS, and now I'm triyng to start a timer in PWM mode. The MCU is a STM32F303CCT6, and the timer I want to use is TIMER3, activating a led on PA6. I didnt modify any clock, so I supose the MCU uses the HSI clock at 8MHz.Thi...
Trying to get best of STM32F373CCT6 & its differental moded SDADC1 for a pressisios bridge type sensor.Datasheet's say that the SDADC speed limit is 50kS per second.Ive reached only 68uSec (~15k) for thisHAL_GPIO_WritePin(GPIOA,GPIO_PIN_4,GPIO_PIN_SE...
STM32F7 HAL_EXTI_SetConfigLine() causes a Hard Fault whenever the parameter is one from the HAL_EXTI_GetConfigLine(). CubeIDE 1.2.1STM32Cube FW_F7 V1.15.0Nucleo F746Following is the sample of the sequence. This code retrieve the EXTI configuration of...
First I want to say that I am a newbie in this field. I am trying to upload and debug a code on a custom-made board based on STM32F303CB chip through a NUCLEO-F446RE board. I am using Eclipse IDE (2019-12), a GNU toolchain and a SEGGER J-Link debuggi...
Hi,I am using STM32F072VBT6. I need a PWM waveform output that is gated with a PWM output of another timer channel.I am using TIM3_CH1 as the master that will control the output of another PWM of TIM2_CH1. Please refer the image for clarity. I need w...
In an application, for reasons I don't want to discuss here I try to write the program being binary fully compatible for both 'F407 and 'F427. Sticking to the 'F407 as subset, the 'F427 seems to be pretty compatible, the only exception I am aware so ...
the RM0090 reference manual for 2014 ,in the description of the “Chip Select togglest�? different from RM00990 reference manual for 2018，which one is correct？The results of our tests are consistent with reference manual for 2014,Is it wrong in RM0099...
my English is poor，In the same program ,cpu 407 do not have this problem,only happened in 427，somtimes.It's like 2.3.4 Corruption of data read from the FMC. in <Errata sheet - STM32F42xx and STM32F43xx - STM32F427/437 and STM32F429/439 line limitati...
