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...
Posted on February 21, 2013 at 23:36Hello all,Can someone help me please?I must be doing something wrong because I can't do something so trivial...I'm trying to output HSI over MCO1, it must be something straightforward, but...void cpu_init_mco( voi...
Posted on February 25, 2013 at 23:52Hello, Can someone inform me whether I can use (or do I need) USB CDC Driver on Windows CE. I am planning to connect STM32F4 Discovery to Cuwin Touch Screen panel which is operated on Windows CE. I checked the 're...
Posted on May 14, 2012 at 17:40hi, i am working on the stm32discovery i am trying to increment a timer (timer2 channel 1) each time the signal on the pin PA.05 is rising but the timer is random incrementing and not at each rising edge of the signa...
Posted on February 22, 2013 at 11:48Hi everybody, hi clive1! in an older PIC design, I use to store calibration data in flash. Then, an update can be done with values received via serial. With PIC, the pages to work with are smaller. With STM32F4xx ...
Posted on October 31, 2012 at 21:57I am communicating with a slave device and after the generation of the start condition, I am not seeing SCL and SDA pulsing. Below is the code: void DS2482_Init(void){ GPIO_InitTypeDef GPIO_InitStructure;...
