I have been battling an issue for a while where upon a watchdog (WWDG1) timeout, the system was not correctly reset. I was finding that the CPU and NVIC are reset but all the peripherals are not reset after a watchdog reset, they keep their exact reg...
Hi all,I would like to add on my project a custom bootloader using an UART.In my project I have already an external QSPI loader used by TouchGfx to transfer the new graphic contents while programming my stm32h743 microcontroller.This is my first expe...
I have implemented 3 ADC with DMA. ADC1 with DMA1 stream 0 , ADC2 with DMA2 stream 0 and ADC3 with BDMA channel 0 Resolution : 16 bit , ADC clock : 7MHZ , Sample : 8.5 cyclesAll these ADC are Time trigger for that i am using timer 1 as center aligned...
Hello, everyoneI'm trying to make an I2C slave with a Nucleo-F401RE.Writing from Master (Raspberry) to Slave (Nucleo) works very well.But the response of the Slave (Nucleo) to a read command from the master (Raspberry) does not work.I tried a very si...
I am trying to set RTC-alarm event to wake up an STM32F103C8T6 from sleep-mode (not standby, not stop) and it works once, but subsequent alarms never wake the MCU up. Nothing I've tried seems to work and I no longer have any idea how to fix this.The ...
I am thinking of turning on ADC with DMA when analog watchdog detect certain level of signal. Then I would like to turn on ADC with only watchdog first and when LevelOutOfWindowCallback() is called ADC with DMA starts. I tried code below but it didn'...
Hello,I AM working on the stm32f0760c6 custom designed board in that our controller adc values are not zero when the pin was floating(not connected to any analog sensor). how can we make it is zero(when sensor is not connected), if I use a capaci...
I'm trying to get ADC values from multiple channels of ADC1 of STM32F103C8T6 using DMA where conversion is triggered by TIM3 every 1ms. However, I'm not seeing the right values. I tried the polling mode and that worked fine. Here is the main function...
Hello,My goal is to evaluate several ARM Cortex-M4F chip manufactures and select the one that best fits my needs for building IoT devices. I will admit that I am on the learning curve and that I’m doing this on my spare time. I’ve read a lot of books...
