STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on April 24, 2014 at 22:15I am having trouble using I2S to connect an audio codec, CS42L55, to the STM32F405. When I configure the STM32F4 to be in MasterTX mode, the codec reports that there is a clock ratio error. With an oscilloscope, I me...
Posted on April 23, 2014 at 02:21Guys, I'm just wondering, Is it possible to use my old DDR SDRAM PC133 module from my old PC for FSMC on STM32F103VCT6, I can see one chip for 8Mbytes, not bad for my experiment and it's cheap... The type is GM72V66...

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...
