Posted on April 24, 2014 at 17:27 Dear everybody, I found a strange behaviour, which I have no explanation for currently. This code doesn't work NCAN_Outgoing.DLC = 8; NCAN_Outgoing.ExtId = 0; NCAN_Outgoing.IDE = CAN_ID_STD; NCAN_O...
Posted on April 24, 2014 at 19:43Hi,I have to revceive data from a device that is sending I2S with 8 bit data format....The smallest I see is the I2S_DataFormat_16b,...Is there a way that I can receive correctly this 8 bit data format?Thanks
Posted on April 25, 2014 at 09:43Hi , I am working on a project that requires the GPIO to be set to tri state HIGH/LOW/HIGH IMPEDANCE mode.Is there a way to set a gpio on STM32F4 to high impedance ?Thanks.
Posted on April 25, 2014 at 12:10 Hi all, I would like to interface a NOR Flash using the FSMC. However I cannot find a tutorial how to compute ADDSET and DATAST. I found application note AN2784 but it is forSTM32F10xxx. Also looking a...
Posted on March 14, 2014 at 10:16Hi everyone,I have develpped a bootloader firmware for the STM32F415ZG microprocessor board. I developed it with Keil uVision 4.23 IDE and used Keil ULINK2 debugger.When I have the ULINK2 connected to the board SW po...
