Hello,I'm working with STM32F410RB , My question is not related to code but it's architectural. I'm using DMA uart to communicate with another device, i noticed that dma buffer change its content before my code processing the data. So i'm loosing som...
I am working on Nucleo-h745ziq board .I have to board i am doin the loop-backing. One board as master and another as slave. First I configure as both board as full duplex. After switching the switch the mode get change the MASTER only transmit and s...
DS11189 Rev 7 (May 2021), STM32F469xx Datasheet - production data, seems to omit the Flash module sectors information? Where can Flash module organization for f469xx be found?
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 ...
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...
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...
