Posted on June 14, 2017 at 12:20Hi,I'm using STM32F303VB in my custom hardware that has USB.When using STM32CubeMX I see a lot of Standard USB Device classes that I can use (Audio Class, HID, Custom HID,.. etc..). But I do not see an option for Vend...
Posted on March 23, 2018 at 03:40Still having issues with tracking down how this is supposed to work using F746G-Discovery board, F7V1.11.0 CubeMX, with the board configured to use FreeRTOS, FatFs, SDMMC, and DMA. Everything is fine up to f_close, ...
Posted on March 21, 2018 at 15:12 Hello there, I am trying to connect 3 sub-systems: qspi flash memoryFatFSUSB mass storage device I have successfully written low level drivers for qspi and have connected it with FatFS middleware. I can read ...
Posted on March 23, 2018 at 18:36Dear all,I am having some issues making the USB FS to work using the STM32F405 microcontroller. The setup is pretty simple by following the guidelines found in this forum, however it still not working. My custom boar...
Posted on March 23, 2018 at 11:46Hello,I am trying to use the character LCD with I2C expander together with BluePill bard (STM32F103C8T6).I have the Makefile project generated by STM32CubeMX (latest 4.25).Because LCD was not working (not initialized...
Posted on November 22, 2017 at 20:27At least on the SMT32F103x parts, the SWJ_CFG bits in the AFIO_MAPR register are write only. Reading these bits is undefined. All of the __HAL_AFIO_REMAP macros in stm32f1xx_hal_GPIO_ex.h do read/modify/write op...
Posted on March 21, 2018 at 10:00I have STM32F103C8 as a SPI master and a STM32F407VE as a SPI slave.I haven't worked with SPI enough to find optimal way to write communication mechanism, and earlier work with SPI only on AVR and Texas Instruments C...
Posted on March 21, 2018 at 17:35Hi,It came to attention that there is bug in stm32f7xx.h for CMSIS version.__STM32F7_CMSIS_VERSION using __STM32F7_CMSIS_VERSION. It cause compilation error. So existing code :&sharpdefine __STM32F7_CMSIS_VERSION_MA...
Posted on January 22, 2018 at 19:15The HAL documentation http://www.st.com/content/ccc/resource/technical/document/user_manual/41/78/8e/63/f9/32/44/12/DM00113898.pdf/files/DM00113898.pdf/jcr:content/translations/en.DM00113898.pdf seems to correctly...
Posted on February 07, 2018 at 13:33 Greetings. I wasted a lot of time trying to figure out what is wrong with I2Ccommunication and thus found this issue. Following code works as it is expected to (it changes corresponding CNFy bits to 0x03 and M...
