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 December 20, 2011 at 20:21I am using TIM2_CH3 configured for a DMA1 request on Stream1_Channel3. On Output Compare I would like TIM2_CH3 to trigger SPI1 to begin a DMA2 request on Stream5_Channel3. How do I associate the TIM2_CH3 event wit...
Posted on December 13, 2011 at 15:35Hello there, I'd like to set up an ADC and DMA so that converted data is directly written into an array in memory. I modified the ADC3_DMA example but it doesn't work correctly. I replaced ''ADC3ConvertedValue'' ...
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 ...
Posted on December 15, 2011 at 11:24Hi , Is it possible to run RTC with 40khz LSI when power is off and CPU works on battery only? #rtc #lsi
Posted on December 14, 2011 at 20:52Dear all, I've not found a related topic. Right now I've checked with the demo of mass storage device the possible maximum transfer speed. And it looks like ~500kByte/s, for writing to the device. The define at us...
