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 23, 2013 at 20:04Hello, for those who can be interested in programming an STM32 with Python, have a look at this Kickstarter project : http://www.kickstarter.com/projects/214379695/micro-python-python-for-microcontrollers. the pro...
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...
Posted on November 22, 2013 at 17:04how to use the accelerometer stm32F4 for application control motor??
Posted on February 26, 2013 at 07:38Hello, I try to make I2C on PF6/7 on the STM32F051C6 (48 Pin device) working. To get what AF to use, Ref man points to the datasheet. But the datasheet is not clear to me, it has a AF Table for PortA and PortB an...
Posted on November 21, 2013 at 17:52Hi,I am using SPI2 with DMA1 on STM32F427 to communicate with an external processor. The problem is that when the data on MISO and MOSI pins (PB14 and PB15) are somehow corrupted i.e. the data comes out as shifted...
Posted on October 23, 2013 at 21:20Using the 3 channels of the SDADC in Single Ended Zero Reference Mode, Gain 1, with a SDREF at 2.5V. Spec lists gain error of -2.4% to -3.1%, but our devices appear to have a positive gain error of approx +2.8%. ...
