Hi all,A USB device should pull up DP when it detects VBUS power only. This is described in the USB standards and ST AN4879 factsheet. Question 1. Is there any other (smarter) way with the STM32L072 than to monitor VBUS power on a GPIO yourself (via ...
I have buy STM32F407VET6 discovery in the past, and for some reason i need some more. been looking on the local marketlist on my country most don't sell it anymore, and my past store still hasn't restocking it yet, and i'm found similar board with sa...
here are the functions:/*** @brief Return the OSPI error code.* @PAram hospi : OSPI handle* @retval OSPI Error Code*/uint32_t HAL_OSPI_GetError(const OSPI_HandleTypeDef *hospi){return hospi->ErrorCode;}/*** @brief Return the OSPI handle state.* @PAra...
Hi Guys,This is driving me mad!So this works perfectly echoing characters via uart8: int ch = 'A'; while (1) { HAL_UART_Transmit(&huart8, (uint8_t *)&ch, 1, 0xFFFF); HAL_UART_Receive(&huart8, (uint8_t *)&ch, 1, 0xFFFF); } Now if I have getchar ...

Hi, I am trying to implement printf with UART using DMA. The problem is when i use consecutive printf's in my code, transmission of the first data is not being waited. I implemented a control block to check if the transmission is completed but it doe...
Hello,I need to power the NucleoF103 development board using an external 3.3V power supply. I have read in the NucleoF103 manual that this is possible by removing SB2 (to disconnect the voltage regulator output) and SB12 (to disconnect NRST). I also ...
Hi. I am using STM32L010C6tx processor. I drew the circuit myself. I did SYS-> debug serial wire. I was able to install without any problem. But sometimes "Memory Programming...Opening and parsing file: ST-LINK_GDB_server_a14408.srec File : ST-LINK_G...
I'm developing a board with an STM32L452 and would like to find out if I can low the power consumption.The current draining is 35mA, my goal is lower it to 20mA or less to achieve a requirement.I've tried putting the device to sleep putting SLEEP MOD...
I want to receive the data from one nucleo board through CAN protocol and it should trigger the DMA and shuffle the received data and transmit back again to another board.In ioc configuration I am unable to enable the DMA (peripheral to memory and vi...
