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 June 11, 2014 at 10:58Hello,I can't found a guideline for migrating from STM32F2 (207) to STM32F4 (429) on st.com. I find only STM32F1 to F2 or F4Has anyone docs or note about it? Or some reference to doc...Are there any different between ...
Posted on September 25, 2012 at 00:36When I use DMA on the transmit SPI2 chanel (STM32F205) I consistently get FIFO errors at the end of the transfer, even though the FIFO is disabled. I verified the DMDIS flag is 0 in the DMA_SxFCR register but th...
Posted on June 10, 2014 at 04:55The scenario is as following:1. Data is transferred by DMA from a camera or from an ADC via SPI to SRAM2. Computation should be performed based on the incoming data.3. The computation includes multiplication with look...
Posted on June 10, 2014 at 22:51 Hi all; I'm trying to make two boards communicating with SPI. The Master is a board based on PIC µC and the slave is Discovery F3. The protocol that i have to establish is as follows: 1) The master...
Posted on September 23, 2012 at 12:34Hello. I colided with the following problem: ADC1 doesn't start conversion in injected channel from TIM1 CC4 event. Below I quote a piece of code of my initialization of ADC1 and TIM1:RCC->APB2ENR|=RCC_APB2ENR_TI...
Posted on June 11, 2014 at 15:04 Hi, I am measuring the distance with ultrasonicsensor that has both one pin for the echo and trigger signal. For this task I'am using 2 timers: TIM2 AND TIM3 TIM2 is responsible for the periodic tri...
Posted on May 13, 2014 at 12:03Has anyone got any experience using the SPWF01Sx series of wifi modules? I recently got one and am having some early teething issues just getting it to join networks...
Posted on June 11, 2014 at 11:53Trying to generate a simple PWM Output using STM32-Mat Timers 1 and 8 work flawlessly, however the other available timers (2,3,4,5) all produce error 6200: TIMx-IRQHandler multiply defined by stm32f4xx.o and PWMTest.o...

Posted on June 11, 2014 at 09:04 Edit: Ok, I used the scope and measured the signals. Actually there is a lot of noise on the inputs. Also connecting the pins directly to ground isn't a good idea as well. So, I guess this threat can be close...
