Hi i am unable to see SCL,SDA signals in logic analyser. Connected Pullup resistors to Scl,Sda pins. Interfaced with PCF8574 IC (I/O Expander) ,Hardware Connections are fine but i am not getting even clock(scl) in STM32F401RE#include<main.h>#include<...
While I was looking for H7 DMA data,I saw the article below that DMA is not working on the H7 device.https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesSolution 1 from that article is shown below.--------------------------...
/* Peripheral DMA init*/ hdma_sai1_a.Instance = DMA1_Stream0; hdma_sai1_a.Init.Request = DMA_REQUEST_SAI1_A; hdma_sai1_a.Init.Direction = DMA_PERIPH_TO_MEMORY; hdma_sai1_a.Init.PeriphInc = DMA_PINC_DISABLE; hdma_sai1_a.Init.M...
Hi All,To get around a problem I was having with timer capture using DMA (another topic) I changed my timer code to use interrupts. The seems to work when I debug step through it but not when I run. I am using TIM8 in input capture mode for CH1 and C...
The STM32H743 datasheet says nothing about clocking the timers. Reference manual has a chapter dedicated to each timer's counter clocking. For each type of timer the only clock is so called "Internal Clock" CK_INT . What is it? Opened my project's Cu...
Hi, I'm trying to execute an interrupt with the pin PCO with stm32f303re Nucleo board, but the interrupt routine never executes, actually, it just stops the program. this is my configuration code for the interrupt: //set gpioc 0 as interrupt _...
I have this sentence and please give me a feedback that is it true or not true."The problem was that DTS had what appeared to be a bad batch of STM32F030C8T6 processors that would fail to reboot after a power off/on cycle once they reached higher tem...
I describe in more detail what I did. The STM32L051C8T6 controller operates from an external oscillator at a frequency of 20 MHz, a general purpose timer TIM2 with a prescaler 199 and a counter period 99, thus the counting frequency is 1000 Hz. The 4...
Please help me upvote In the CMSIS-mandated device header, use a struct to define DMAMUX registers.Thanks,JW
My testing appears to consistently show that whenever I update the calendar time and date, the RTC_SSR I read straight after the set operation is the RTC_PRER_PREDIV_S value.However, I fail to find this explicitly stated anywhere? Maybe its obvious, ...
