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 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...
Posted on September 05, 2012 at 11:16HiI've downloaded in the MCU TIM complementary signals example, provided in the ST Peripheral examples. PA8, PA10, PB13, PB14 and PB15 are working correctly. However, PB12 (whose complement is PB14) is displaying...

Posted on June 10, 2014 at 16:34 For several years I have developed software for an STM32F103 target using Eclipse/OpenOCD/Olimex ARM-USB-OCD. Recently my hard drive failed so I replaced it and re-installed everything. My project will not now ru...
Posted on June 10, 2014 at 16:54Hi all, I have a project where I need to deal with 4-to-8 bit and 8-to-4 bit conversion and so I have a questions: 1. I know that I can do DMA to/from GPIO but what is maximum speed of that operation. Can I go up to 2...
