My work environment is heavily disturbed by EMP which particularly has frequency of 2.44GHz. I measured the frequency and 2.44GHz is most frequently affecting, but 900Mhz range has other influences to MCU operation.Sometimes, ST-LINK V1 and V2 is dis...
In the h745 reference manual, the RAM region of memory is write-back while the code region is write-through. According an app note, cache coherency issues can be avoided by using a write-through ram region. In the h7 the sram sections are aliased in ...

Posted on March 15, 2016 at 18:16 I'm trying to debug an I2C interrupt handler that I didn't write, on an STM32F207ZG. My problem is that after sending a Start, when waiting to send the Address byte, a Stop happens. What am I doing wrong that mak...
Hi, does htim4.Instance->CNT = 0 resets the counter value in TIM4_CNT ?Does it guarantee atomicity ? Thanks in advance!
Hello, My company is evaluating a graphical application according following specs. Res. 640x360, RGB565 interface, JPEG / JPEG stream images / videos /animations. The selected uC is STM32V3A3VGT3. Data information for videos and images will be stored...
Hi,Is there a way to create trigger event on each rising pulse of external clock gated by internal clock? The closest that I got is to create trigger event on each 2nd pulse of external clock.I use TIM2 in gated mode triggered by internal clock, ETR2...
