In function USB_EP0_OutStart is: if (dma == 1U) { USBx_OUTEP(0U)->DOEPDMA = (uint32_t)psetup; /* EP enable */ USBx_OUTEP(0U)->DOEPCTL |= USB_OTG_DOEPCTL_EPENA | USB_OTG_DOEPCTL_USBAEP; }In my opinion enabling endpoint should be out of DMA condi...
So I'm working on a hardware prototype which utilises two STM32F303s on two separate boards. I need to provide DFU firmware update functionality so that a package can update the firmware of either or both chips. The master board contains the USB conn...
I just got the eval board.I am clueless , too much info on the site , can someone point me to a get started pdf or something ? Shouldnt I see the board in the Audiweaver server? Where it now says native?I have Touch FX and the audio weaver ,but neith...
Hi,i'me trying to develop a firmware for STM32F107RCT with a 4 port Microchip switch.The switch has 3 port with phy and 1 port in MAC/PHY mode. I've set it in MII PHY mode.It get's the 25MHz clock from MCO1 pin (set HSE that use a 25MHz quartz) and g...
I have my window comparator fully working Triggering an interrupt every time it crosses the thresholds .But my problem now is how do i know if it is positive or negative edge..?I am using the HAL for this.Thanks
I have a "hello world" example that works fine on a STM32F765Z6T6 (custom board). It basically waits for a USB serial port to be opened on the host side, and outputs "Hello world" every second over and over again. Unfortunately it's based on libopenc...
Hello,I use an STM32F4 as a USB CDC device, I would like to add the MSC functionality (SD card). I have read many threads, but have not found a way to implement it.Is it possible? What needs to be adjusted?Does anybody have found an introduction or t...
I have the USART2 setup for RTS/CTS flow-control and Rx DMA for one byte transfers into a ringbuffer. The problem isn't that the ringbuffer is overflowing, it appears that the DMA process is stalled during the erase flash pages operation and the UART...
