Posted on February 26, 2013 at 06:37While trying to get an interrupt working that monitors the USB VCC voltage to detect USB cable connection/disconnection, I found a very strange problem. Whenever USB is enabled (as it should since that's what I'm ...
Posted on February 23, 2013 at 10:32 Hi , I am using the following code to configure my external interrupt on PH10 , PH11, PH However , the interrupt does not occur when a signal is applied to PH10 , bothe PH11 and PH12 is working ...
Posted on February 25, 2013 at 17:46Hi Is it possible to connect an external I2S microphone to the stm32f4discovery? I know that the board already has a MEMS mic but I need to use my own microphone. Can I route the signals (MCLK, SD, WS, SCLK) to th...
Posted on February 26, 2013 at 10:53I am using an STM32F4xx MCU and have configured it for external interrupts (EXTI) on PH2 (rising edge). Everything works OK until the odd occassion when the input to PH2 is left high at the end of the ISR. In this...
Posted on February 22, 2013 at 10:48I’m using a slightly modified version of the USB CDC example on STM32F205. The modification is that I’m terminating the STM32 end with a simple command line rather than tunnelling to and from a UART. This is a...
Posted on February 25, 2013 at 14:18 Hi, I'm switching from a stm32f100 to the stm32f051, most of the code is working already. but the usart1 does not work. The output doesn't change when I am trying to send something. Here are some snipp...
Posted on February 25, 2013 at 13:01 This is a piece of code from usb_core.c/* set Rx FIFO size */ USB_OTG_WRITE_REG32(&pdev->regs.GREGS->GRXFSIZ, RX_FIFO_FS_SIZE); /* EP0 TX*/ nptxfifosize.b.depth = TX0_FIFO_FS_SIZE; nptxfifosize.b.startaddr = RX_...
Posted on February 26, 2013 at 01:13HI ST COMMUNITY, I just wondering why my stm32f4 Discovery board seems to slowed down, I am still using the same program. I've just powered it on as usual and make it do its usual task of capturing data.. Then whe...
