Posted on December 20, 2015 at 03:00I have seen, that there exist a host mode MTP driver for STM32 in STM32Cube. Anyway there are ever recurring questions if there is the possibility to write data simultanously in datalogging appliation to an SD Ca...
Posted on July 27, 2015 at 22:13Hello, How to easy increase external sdram from 8MB to > 16MB? Do you know any chip 8Mx16, 16Mx16, 32Mx16 and the same package? In my opinion this kit should have minimum 16MB ram... #stm32f7-disco-sdram-uclinux-et...
Posted on December 15, 2015 at 17:20 I have problem with STM32f103 FatFS library. If I start it with SD_SetDeviceMode(SD_POLLING_MODE) everything works OK. But when I change it to SD_SetDeviceMode(SD_DMA_MODE) it is fired HardF...
Posted on November 05, 2015 at 14:52I am implementing new class driver for USB device. Basically this is PTP/MTP compatible class driver for device. I run into problem during USB transmission. For now I have device descriptor configured and transfe...
Posted on December 15, 2015 at 20:08I've found a bug where the order of the interrupt handlers causes the HAL driver to get stuck in TxState==1, causing CDC_Transmit_FS() to always return USBD_BUSY leaving it unable to send any more IN transfers.The...
