I've enabled the I2C controller and ask it to send a start condition on the bus, and it does, however, as soon as I write a data byte to the TX register, it releases the bus and raises an arbitration lost flag. How can this be possible when there is...
While testing the exception traps routines I ran into an odd problem with the SRAM2 parity check on an STM32L496. As part of a unit test I force a usage error by attempting to read from 0x3000 0000, an invalid address. The usage vector is called co...
I am using the adanced control and the general purpose timers witch the STM32F334K8T6 to drive one half-bridge and one full-bridge.The problem lies with the full bridge:I use the general purpose timer with two times asymmetrical PWM (center aligned m...
Hi,I'm using an STM32F334 in a Nucleo development board. I have flashed the device both with STM32 ST-Link utility and after finishing, I connect the development board to an external supply and the MCU does not start running unless the RST button is ...
How do these series differ from each other? Especially "Cubewise"?Are there notable differencies in the Atollic/Cubeide user's point of view?Is this G4 basically F3 with F4 core?
Hello everyone, i have a problem about this condition, i use it for transmit a only one character to a function ( ChooseMenu )Actually i convert decimal to ascii with if condition.. if (__HAL_UART_GET_FLAG(&huart3, UART_FLAG_RXNE) == SET) { ...
I understand that, in order to put the F750 to sleep AND reduce power supply heat during sleep, we should use:HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);WFI();But I have not read what happens when the CPU is not sleeping (du...
Hi :) I am trying to play audio from an SD card to the built-in DAC of my Nucleo-F446RE.I am using DMA, and one buffer of 10240 size, which I want to update continuously using the Transfer Complete / Half Complete callbacks.The code is quite simple, ...
HiI am currently trying to create a delay function on my STM32F407 discovery board using a free running timer (I used TIM6 for this purpose). I set my counter clock frequency as high as possible and my max counter value to 0xFFFF. Based on my calcula...
