Posted on August 09, 2012 at 10:52Hello, One simple question please: Why It is mandatory to Set PA11/PA12 for USB data (+/-) as Alternate Function (AF) ? in STM32F103 for example I’m asking this because in other products such as STM32L , it worki...
Posted on January 27, 2014 at 17:31I've got the example working using the on board button and now I want to use an external button on CPIOC - 11. I've used this button with GPIO_ReadInputDataBit with PuPd_UP. I've converted over the sample code but ...
Posted on January 27, 2014 at 10:21Hi,Have anybody tried connecting camera with this board?I see that some of the pins are interfering example PA4 (DCMI_HSYNC interfering with LCD_VSYNC).Maybe someone figured how to use the camera with the LCD on bo...
Posted on January 27, 2014 at 13:42Hi,I have problem with SPI3 and st-link debugger. CLK pin is always unaveilable.I configure MCU to not use JTDO but in debug mode when I look at AFIO register there is written some other value for SWJ_CFG(always 0x...
Posted on January 23, 2014 at 08:08Hello, I'm using a STM32F439 with the MT29F2G08 NAND from Micron. When I read the NAND ID on Address 0x20, I receive the correct ONFI codes. When I Read the ID on address 0x00, I read the correct Maker ID, but the ...
Posted on January 27, 2014 at 06:13Hello,I have many questions about ADC Multi-Channel to ask and thank you for your helping. I used STM32F417ZGT6.1. I used ADC to read voltage in 2 channel with below setting.01./* Enable ADCx, DMA and GPIO clocks *...
Posted on January 27, 2014 at 11:22 Hi, Basically I have an issue with the ADC1 interrupt on EOC. It fires once in continuous mode but then after reading the value (thus resetting the EOC) it never fires again. Im stumped as to why this happ...
Posted on January 16, 2014 at 07:24Hello, I have been working with an STM32F27 in an audio application. I am using the SAI module with both blocks. Block A is a master RX block, block B is a slave TX block synchronized to block A. The interface is s...
Posted on March 13, 2013 at 14:54I would like to use SPI3 on STM32F4-Discovery. And the configuration is referred to the demo provided in the library. But when I use SPI_Write to debug it, there is no clock signal tracked by oscilloscope. The config...
Posted on January 21, 2014 at 03:09I have quite a big code, I might post it(part of it) at a later point, but first I wanted to ask if anyone can think of any reason why my microcontroller does not fire a DMA interrupt when the only thing I do is re...
