STM32 Interface with FSMC and DMA

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 ...

STM 32 F4 Discovery I2C Hanging Up

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...

STM32f051C6 PF6/7 AF for I2C

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...
