Posted on December 15, 2011 at 20:30Hello, I'm trying to put USB communication in suspend mode, but when I force wake up, just can read data from PC, but nothing is sent. The interrupt for correct Tx transmition isn't fired. The end point is well co...
Posted on December 19, 2011 at 10:40Hi, ADC resolution is working for ''ADC_Resolution_6b'' and ''ADC_Resolution_12b'' but not working for ''ADC_Resolution_8b'' and ''ADC_Resolution_10b'' resolutions, they're same with 12-bit resolution. Does anyone...
Posted on December 19, 2011 at 00:33Hi, I am a complete novice to the stm32f4discovery, I have made a 8x8 RGB led matrix using 4 74HC595 8 Bit Shift Registers with only 3 wires going to my now fried arduino, from the old arduino pins I had the 74HC5...
Posted on December 18, 2011 at 01:56Hi, I am trying to get the quadrature encoder working. I found and copied code from these forums for setting it up with a different micro controller but the one on the STM32F4 does not support RCC_APB2Periph_GPIO...
Posted on December 16, 2011 at 16:33Hello,I've recently bought a stm32l-discovery board and I want to start developing for the onboad processor. I have some previous experience with 8bit atmel microcontrollers but not with (32bit) ARM processors.I ...
