Does erasing an already-erased Flash page contribute to wear?Reason for asking: the EEPROM emulation code erases pages which should already be erased without checking that they are already erased - is that just laziness, or is it because there is act...
Hello,I'm working on an audio application using a NUCLEO-H723ZG, where I am trying to setup two DMA channels for full duplex audio. I am using the Zephyr RTOS with a modified I2S driver I am writing since the one in mainline zephyr is non-functional ...
Hello All,Do you support all UVC versions on UsbX Azure RTOS running on STM32H735XGT6? Or do you have some restrictions?Best regards,
Hello everyone, I'm trying to use MPU6050, HMC5883L and MS5611 all together in a project with an STM32F446RE. The problem is, while every components all work fine alone, when is use MPU6050 and HMC5883L together, it doesn't work. By not working, I'...
I want to use STM32H7 SPI to drive DAC chip to generate sinusoidal wave. Can you recommend me relevant routines or ideas
I am having issues with the use of HAL_CAN_RxFifo0MsgPendingCallback. I've set every configuration (filter, start, interrupt, notification, and priority), but the function doesn't seem to be called at any time.Most of the code is generated from the c...
Hello ST expert.I'm trying to create SPI communication as shown in the CubeMX image.and the following code/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c ...
I have a signal biased around the VREF output (2.048V) of an STM32G4. I have a comparator (COMP7) peripheral configured to compare this signal to VREF and it fails. If I set the second input of the comparator to DAC2 and set the DAC2 output value to ...
Hi,I am facing an issue with IWDG in STM32G051G6U6.HAL_IWDG_Refresh(&hiwdg); not refreshing IWDG and the core resets after IWDG overflow time.IWDG overflow is set at 13Sec (varying wrt prescaler) and I am refreshing it at every 1 sec.Counter presc...
Hi,I'm relatively new to the STM32 world and I'm becoming frustrated that I can't make a simple UART work. No DMA, no interrupts just trying to send bytes out of the UART and then receive them. Here is my setup code: void UART7_Init(void) { GP...
