Posted on March 02, 2016 at 00:07I am using the Stm32CubeL4 to generate a USB device with a CDC class. This is on a custom board. I am not using the USB ID line or VBUS. It runs, but USBD_CDC_Init() is never called. On the Windows side, I see an ''...
Posted on March 04, 2016 at 21:12Hi All,I am now trying to building a USB sound card with microphone.When I use USBlyzer to monitor the usb communication, it didn't have ''set configuration'' and start fails.which part is wrong?Thanks.
Posted on March 04, 2016 at 06:47I'm developing an application using the stm32f429 and have completed the firmware. The total size is only ~300kB so I'm trying to downgrade to the 'VE' version with only 512kb as it's substantially cheaper.On my prot...
Posted on March 02, 2016 at 16:40Hi all,The issue that I am having is that I having is last night I was programming and found that my code suddenly stopped functioning completely. After running in debug mode I found that the code immediately enters ...
Posted on February 26, 2016 at 02:55I'm trying to deal with the setting clocking of STM32F103 MCU without the use of third-party libraries.I wrote several functions for this: http://pastebin.com/kLQS9UmwIf I setup clocking by stm32_rccUseHSE, then e...
Posted on March 04, 2016 at 18:00Can I use an external oscillator module to drive a clock directly into the 'oscillator in' pin?ST documentation only shows crystal with load capacitors. #stm32 #oscillator #-
Posted on March 04, 2016 at 17:18Hi,Anyone knows if it's possible use the ULPI interface for MCU-to-MCU communication??I need to have a high throughput bus communication. Even SPI is not fast enough.I am using the STM32F427.Regards :) #ulpi-stm32...
Posted on March 04, 2016 at 15:32I built a test program using STM32CubeMX to test the STM32F746 in TCM flash interface mode (selected from the dialog box brought up by using the Cortex M7 button on the configuration tab). I imported the project int...
Posted on June 03, 2014 at 18:01Hi, I've been trying to get SDIO working on the STM32F4 Discovery board. I've wired up the SD card and created a basic project using CubeMX. The MX_SDIO_SD_Init() function completes successfully but I cannot get the H...
Posted on March 04, 2016 at 09:19 I worked with stm32f373. To reduce power consumption I change the Hclk to 24Mhz and 48Mhz System clock. (use AHB prescaler to /2) But I confused by flash setting. reference manual said that the latency is 000: Ze...
