Posted on March 26, 2016 at 07:54Good afternoon, I have problem in use ADC in differential mode. In differential ended mode ADC do not work on my device and Nucleo-F334R8 also. I use Ac6 System Workbench, CubeMX and ST-Link V2 for develop. I do not...
Posted on April 02, 2016 at 04:16What is the good way to store video capture from camera to microSD?I am using the lib ''sd_diskio.c'' to storage frame size 480x272x2 bytes but the quality is terrible, only 1 frame/second. It seems it took too much...
Posted on April 01, 2016 at 16:47 That's right, the very same acknowledgement error found during calls to CAN_init(CAN1, &CAN); is found waiting on the INACK bit to be cleared. And yes, the CAN clocks are turned on. This error is n...
Posted on April 01, 2016 at 19:24I need to have a modest amount (say 512 bytes) of EEPROM emulation on my F030 design. I found app note AN4061, but it only allows for swapping between two 1K pages of flash.Does anyone know of a better implementatio...
Posted on March 31, 2016 at 14:20Hi to all, I encounterd a problem using Real Time Clock. After I initilaized it, everything seems to work, but when I reset MCU it stops and I can restart my board only powering it off and then on again. Hereafter th...
Posted on April 01, 2016 at 07:06Hi. We would like to store some data in a backup registers using supercap as an additional power supply. Do you have maybe any recommendation for the circuitry around the supercap? Or maybe an example of it? It shoul...
