Posted on November 01, 2012 at 22:15I turned on a test board this morning and could not program or read the flash area (0x0000 0000 to 0x1FFF FFFF). Looking at the option bytes in FLASH_OPTCR register I see the RDp field set to FF, level 1 protecti...
Posted on June 29, 2016 at 17:57Hi,when I use an example from the SPL package for stm32 F3xx, I notice that although I do have ..._comp.h and ..._crc.h in the include folder, and they are included in ..._conf.h, the corresponding source files are mi...
Posted on July 04, 2016 at 09:30 Hi, I am trying to read the content of an EEPROM,24AA02E48T, using HAL I2C library. There is an example for this task which has been done in SPL instead of HAL and can be found athttps://github.com/Catethys...
Posted on July 01, 2016 at 06:24I am using STM32F407VET6 board.I wants to ON and OFF LED using GPIO(PORT B & PIN 8). It is 5V tolerant . I reset the gpio and glow the led .But when I set gpio in INPUT mode still LED glowing.It is 5V tolerant.Why? ...
Posted on June 25, 2016 at 01:59My UART interface was working great under CubeMx 4.14 with STM32F7 library v1.3. There are a lot of changes to the UART HAL (not mentioned in the release notes for CubeMx, and there are no release notes for CubeF7) i...
Posted on July 04, 2016 at 07:42Hi,I bought STM32L476RG Eval board. I am using SW4STM32 workbench to program my applications. Can any one tell me from where i can get the examples to start with STM32L476RG Eval board.
Posted on July 01, 2016 at 14:56The register descriptions of the USART mention several times that the feature is optional and might not be implemented on my device (or my specific usart). I've seen such a table with other peripherals, but I can't fi...
Posted on July 03, 2016 at 13:09What is the maximum data rate of the DCMI interface? When you use 10-bits mode, it is 54MB/s. But what about 12-bits mode? Is it 54Mz x 12-bits /8-bits = 81MB/s ?
Posted on June 14, 2016 at 21:24Hi, I noticed that STM32F3 has PC4 and PC5 connected to ST-LINK USART (or at least a bridge needs to be soldered). I wonder if I can upgrade the standard F3Discovery firmware (V2) to version V2-1 which support Virtual...
Posted on July 03, 2016 at 07:14Hi How i can transmit and receive 1 byte by SPI and use of HAL layer for STM32F4 to do for example below routin: while(1) { while (__HAL_SPI_GET_FLAG(&hspi1,SPI_FLAG_TXE) == RESET); temp=0x00; HAL_SPI_Tran...
