Posted on June 22, 2014 at 14:16NRST is pulled high (+3,3V) by a 1,5k resistor, and gets manually connected to ground by a latch, that I press by hand. BOOT0 is pulled to ground by a 3,6k resistor, and there is also a 2k resistor connected to BOOT0,...
Posted on June 21, 2014 at 19:10I have a STM32F105 connected over USB. In order to flash a new firmware I pull Boot0 lowhigh and replug the USB cable. That works. I would like to be able to go into bootloader mode without having to replug the USB ca...

Posted on June 21, 2014 at 09:41Hi, I have a problem with STM32L151xB I use USB in VCP, work very well. ANd I enable ADC in PA0 The adc work very well, but when inizialize USB primarily the USB_Cable_Config(ENABLE); , enable the USB internal pull-...
Posted on June 19, 2014 at 15:29Hello,I'm trying to use SPI master with DMA in full duplex to communicate with accelerometer. I don't want to use DMA interrupts (or should I?).I've managed to activate the SPI with polling mode and got the correct re...
