Posted on July 11, 2018 at 11:56Hi,I'm currently working on a project that needs to 'Read' a File in SDCARD.My MCU is STM32H743XI, and the base for the project, I modified the FatFS uSD standalone application example in Cube FW for H7 V1.2.0, for ST...
Posted on May 02, 2017 at 16:10 Hello, today I updated my Cube libraries to the last release and I found that in stm32f7xx_hal_can.c the HAL_UNLOCK is missing, in HAL_CAN_Receive_IT(). HAL_StatusTypeDef HAL_CAN_Receive_IT(CAN_HandleTypeDef*...
Posted on October 02, 2013 at 15:11Hi, I have some DMA problems with USB HS in Hostmode on STM32F4. I use USB Library V2.1.0 and set up USB HS with internal PHY in Host Mode and MSC., USB FS in Device Mode and MSC.If Compiler (Keil UVision) sets al...
Posted on July 10, 2018 at 21:18Hi,I am using the USB VCP to connect to a PC serial window. I have connected using PuTTY, correctly received messages from the Nucleo, and correctly sent messages to the Nucleo from the window and I could see those in...
Posted on January 22, 2018 at 19:02Hi. Does ST sublicence PID numbers? I use STM32F303Rx micros in my products. Who should I contact. I have tried ST UK office and several distributors, but unfortunately I was not lucky enough to get in touch with a...
Posted on July 10, 2018 at 15:54 Hello everyone, I want to connect one LM5066 to a STM32F072 (currently a Nucleo) via the provided SMBus/PMBus. Unfortunatelly the configuration and daata transmission seem to be very different from I2C, that I ...
Posted on July 09, 2018 at 21:26 I've been experimenting with writing to an external https://www.microchip.com/wwwproducts/en/93LC46B using SPI and I've had mixed success. The data does get shifted out but in an opposite manner. The EEPROM req...
Posted on June 24, 2018 at 06:41Hi everyone.We have run a project on discovery f746 board consist of FREE RTOS , emwin and fat fs sd card library,that it works fine.Now we want to add USB OTG Host in FS mode to our project.We tried to append config...
Posted on July 07, 2018 at 08:45Hello,I am using STM32F401RE microcontroller board and trying to interface LTC1859 with it. I am using STM32CUBEMX to generate code with following parameters for SPI:Data size : 8 bitsPrescaler : 8Clock Frequency : Ch...
