Posted on November 23, 2013 at 14:58I have implemented RTC in STM32F107RB at 50Mhz operating frequency, it works good but the problem is shift in time about 5 to 6 seconds in a day. Is there any correction factor? Here i have attached RTC intialis...
Posted on April 17, 2013 at 08:26 Hi all, I have a ST7753S 8 bit bus, 8080 style, hooked up to STM32F103VE FSMC with config as below. However I find that there are 2 bytes being written every time I write a char. Is this how it works...
Posted on November 24, 2013 at 16:12Hello,I have implemented a USB microphone which uses OS default driver. I define the volume from 0x0C00 (MAX) to 0xE000 (MIN) correspond to +6dB...-24dB.Control in Windows,Linux works. However taper is the wrong w...
Posted on November 24, 2013 at 12:25Hello guys? I have bought some STM32F030F4 chips ?but i donnot know how to program on it?I am confused of the Related firmware?So can someone tell me how to creat a new project using Keil-MDK without the give...
Posted on November 23, 2013 at 23:09I know this is weird, but any help would be great. This is driving me nuts. I'm tyring to use A5, A6 and A7 as SPI for communication with a touchscreen controller. SCLK and MOSI work fine, but MISO (A6) works only...
Posted on November 22, 2013 at 17:19Hello community, I am trying to communicate a STM32F207 uC with a uSD card via the SDIO interface, what I am trying to do is to get the CID of the inserted uSD using CMD commands, and verify that both parts are co...
Posted on November 23, 2013 at 18:50 I'm now trying to receive an image from my OV9655 over the DCMI port and send it then to the pc. With low resolution (160x120 pixel) and saving the image in the ram it worked good. Now I want to geht higher r...
Posted on November 22, 2013 at 17:57Hello, I've been attempting to set up two discovery boards. One as a signal generator that generates a 1 Hz pulse (50% duty cycle), and the other to accept that signal as input capture. I can't seem to get the inp...
Posted on March 21, 2012 at 12:56Hi, I have to read a 15 bit parallel data coming from a camera sensor and one bit as a request signal which tells whether the micrcontroller should initiate memory transfer or not. Does FSMC has any trigger signal ...
Posted on November 21, 2013 at 15:51Hi, I am having a problem with using the I2C on the STM 32 F4 discovery to read 3 DevanTech SRF-08 ultrasonic sensors, There was a previous post on this matter, but it was unresolved as far as I know, clive1 did i...
