Hello,i tried to implement a I2C slave device on a STM32L486.It is working, but sometimes (after a few seconds, minutes or even hours) it freezes/blocks the SCL line. So the master device (also a STM32) generates a error.I have no glue what happens h...
Hi, I have both rising and falling edge enabled for an EXTI interrupt on GPIO. I would like to know what edge the interrupt has been entered on, re-reading the GPIO line is error prone and not viable due to latency. I can have a counter that I check ...
Greetings !I am working on STM32F769 discovery board . I have built OS using Buildroot . I can able to get U-boot prompt through Default debug console (USART1).Here I having a requirement of changing default debug console (USART1) to USART6 . I am a...
Hello, I am estimating the max power consumption of the STM32L412RBT6. Based on the datasheet, I got two results, one is 303mW which is on page 78, and the other one is 0.462mW, which is on page 76( 3.3V X 140mA = 0.462mW). Please guide me on which o...
Hi,I use a STM32F103 as a receiver and an Arduino Uno as a transmitter.I continuously read FIFO_STATUS and STATUS registers. Before I turn transmitter on, everything is okay. Registers tell me that there is no data in RX FIFO. Once I turn the transmi...
I Have STM32F746 Disco and i have a memory section that sould be initialized to zero.and the aim behind this is to keep the memory content whenever the board is rest.but unfortanlty, this section is being clear every time i restart the debuger.the se...
I want to debug and programming STM32 MCU wirelessly using wifi is there any st or other programmer support STM32 wireless debugging and programming?
Hi there !I'm gonna use this microcontroller for one project. I start with configurate one ADC channel and i have a couple of question to ask . 1) More voltage input is close to Vref and more the value i read is close a the input ex: input 2.50 V i r...
Section Memories...The Flash memory is organized as follows:• Two independent 1 Mbyte banks of user Flash memory, each one containing 128 user sectors of 8 Kbyteseach.• 128 Kbytes of System Flash memory from which the device can boot.• 1 Kbyte of OTP...
Is there a possibility to fire DMA transfer on a positive edge on the GPIO pin (PA3) ?
