Posted on October 29, 2015 at 13:58Hello all,I have a strange question regarding speed od USB CDC and USB MSD driver for STM32F429.I implemented USB MSD + eMMC with FatFS support and I am getting 0.51 MB/s write and 0.69 MB/s read speed results with...
Posted on December 04, 2014 at 14:54 Hello, I've modified FatFs_uSD_RTOS example to write in a loop (32k files), which works fine on its own (Task SDCardStream()). When I add another task Process() which only has a calculation loop: sta...

Posted on October 30, 2015 at 16:21Hi, I try again to get my STM32F103 working with FatFS and SDIO in DMA mode. I also use FreeRtos. I got my SD Card working in blocking mode. So if I change in the sd_diskio file the BSP_SD_ReadBlocks to BSP_SD_Rea...
Posted on October 30, 2015 at 20:20Hello, I am trying to implement the LWIP_IAP application on the STM32f40g EVAL board. After compiling the project, the program size turns out to be as follows. Program Size: Code=28150 RO-data=3114 RW-data=260 ZI-d...
Posted on October 30, 2015 at 15:55Hello, I use a Cortex M0 + to develop an application. With this cortex, I need to write in memory and this take 12 seconds by bytes. Could someone tell me if this is normal or not? thanks in advance . I'm using...
Posted on December 09, 2013 at 17:03I am using STM32f4 ,fat fs & SPI mode to interface to SD card every thing works fine .but i want to use DMA to increase read performance.should i go for SDIO to achieve a little more speed or is there any way to t...
Posted on October 15, 2015 at 14:46 I suffered a week and wrote all the same USB Composite device (MSC+CDC). The point is this: I wrote Composite device MSC CDC. Everything is determined by the Manager, MSC works on both transmit and receive,...
Posted on October 28, 2015 at 19:54 Hi, I'd like to say up-front that I'm one of those people thinking that the new CubeHAL is a great improvement compared to the old SPL. However, still there are things I don't understand. For examp...
Posted on March 10, 2015 at 16:12 I am building a microcontroller based on the STM32F302K8 chip and I am trying to send data to host PC via USB. My echo code below based on an example in the forums works: static int8_t CDC_Receive_FS ...
