Posted on February 12, 2013 at 17:54Hi there, I am working on STM32FDiscovery and USB CDC. For this purpose I used:/public/STe2ecommunities/mcu/Lists/STM32Discovery/DispForm.aspx?ID=1311 (I do use CooCox). Well Compiling + Linking successes. The USB...
Posted on July 20, 2013 at 11:30Hello all, I am a bit new to ARM processors. I want to read images from USB Flash drive attached to STM32F4 Discovery.I used the USB host library +FATFS.While debugging I figured out that the device is not getting enu...
Posted on January 11, 2014 at 14:22Hi everybody ,I am biginner with STM32F407 VG Discovery. I am working on a project in wich I must interface the STM32F4 controller with 2 sensors, then I must display some information with a screen using VGA protoc...
Posted on December 29, 2013 at 18:56Hi. I'm developing an Open Source project (a JavaScript interpreter) for STM32 microcontrollers (http://www.github.com/espruino/Espruino). One part of this is a bootloader that mimic's ST's serial port bootloader,...
Posted on January 06, 2014 at 13:38Hi,I am developing an USB HID device with a STM32F4xx microcontroller, using the ST USB stack version.When there are some data to send to host (PC), the device just puts the data into the buffer endpoint. During th...
Posted on February 14, 2012 at 02:38Hi All I am wondering whether anyone has worked in detail with the USB FS device and can share some insight into it? What I have been doing for some days is working on a driver specifically for the device mode and...
Posted on January 04, 2014 at 23:49Greetings, I managed to create a custom Audio library with 17 wave samples (at 11Khz, 16-bit Stereo) that takes 380 KB ROM memory. The library is composed by 17 ''const arrays'' in the same way than the original on...
Posted on December 31, 2012 at 21:15Hello, I want to hold the completion of a EP0 Control transfer by delaying the sending out of the zero-byte transfer or Zero-Length Packet (ZLP). Is there a way to do that? I don't see that the firmware has cont...
Posted on September 10, 2013 at 18:55I was wondering if there is any DFU software compatible with Linux that can be used to upgrade the firmware of an STM32F405 using the USB interface? Essentially I'm looking a Linux version of the Windows DfuSe s...
Posted on December 22, 2013 at 12:56I read the USB CDC/VCP device driver code (STM32_USB-Host-Device_Lib_V2.1.0) and saw that it was built on interrupts.How does the RS receive routine cause the USB device endpoint interrupt?How about the USB host? ...
