Posted on June 08, 2018 at 21:20This may be a galactically stupid question, but I'm an 8-bit programmer making the leap to 32-bit programming.On 8-bit CPUs, we could 'share' (read and set) a 1 byte (char, uint8_t) variable between ISRs and the main ...
Posted on June 08, 2018 at 10:55Dear All, I have an question about CAN bus transmit interrupt. I use STM32F303.In reference manual, it describes when transmit mailbox becomes empty, the interrupt will be triggered.It also means of that when transmit...
Posted on April 29, 2018 at 02:12Hi, trying to get I2S working with 24 bit data. The function call HAL_I2S_Transmit takes a pointer to unsigned 16 bit var so there needs to be 2 transfers to get 24 bits into the I2S. I am using an unsigned 32 bit va...
Posted on June 06, 2018 at 21:40 I am building code to show all jpeg images in SD card and print their names. I use the STM32F746 Discovery. The jpeg decoder crashes after the first image. The Jpg decoder stays at hard fault loop. If I comment the ...
Posted on June 10, 2018 at 23:14Hi,I am using the SDMMC module of the STM32F767ZI to read data from SD cards.In general everything seems to work but I have some problems because I am getting CRC errors when reading 512 byte data blocks from the SD c...
Posted on June 10, 2018 at 04:49Hello,I am working with a STM32F767-NUCLEO board, rev. Z and I am running into a bit of trouble with the example project provided for lwip. Out of the box, I can run the program in debug mode and ping the address acqu...
Posted on June 08, 2018 at 12:34Hi,sorry for this beginner question: I am new to developping with the STM32 platform.I just acquired an STM32F103 evaluation board and the Atollic TrueStudio software.This works perfectly, I could compile and execute ...
Posted on June 10, 2018 at 01:35Hi,I'm using 2D DMA to draw sprites on the screen, but there is a surronding black color around the sprites.So I have enabled the layer color key, and its not working, still there is a black rectangle around it.BSP_LC...
Posted on September 30, 2014 at 15:43Hello, will ST offer a STM32F7 discovery board? If yes, when can we expect it? Regards
Posted on May 04, 2018 at 07:38Hi ST !There is very limited support on STM Touch with TSC application use case on community. Most of the questions are not responded and almost nil application examples.Ti and Renesas are very aggressive with respect ...
