Resolved! When cache is enable DMA not update data
I am working on Nucleo-h745ziq board .I am enable the ADC ch3 and 12 bit resolution ,DMA is enabled and circular mode. I connect the 3v supply to ADC channel. But I doesn't get the updated value when I reset board I get updated value, when I disable ...
STM32H753i-EVAL2 LCD functionality
I am using the STM32H753i-EVAL2 board to test LCD and touch screen functionality. Currently I am unable to generate the code using CubeMX as sample codes dont have the .IOC file. I need help in setting up the LCD and touch screen via CubeMX.It is dif...
STM32H7 watchdog does not correctly reset. Example attached
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...
Custom bootloader on UART (with an existing QSPI External loader)
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...
STM32H743 3ADC's With DMA
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...
STM32 Nucleo I2C Slave answer with Interrupt
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...
Resolved! Wake-up from RTC-alarm works only once
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 ...
Is it possible to use analog watchdog without adc interrupt?
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'...
STM32f070c6 ADC values are not zero. when the pin was floating(not connected to any analog sensor)
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...
