Posted on December 23, 2016 at 13:32Good day. I use STM32L051C8. And I have a problem with GPIOs PA11 and PA12 in push-pull mode. When I trying set signal in 1, it up on short time and drop back. Other ports works perfect, but I can't understand wha...
Posted on December 22, 2016 at 12:43 Hello everyone, I want to ask something about Advanced Control Timers. In RM0008, I saw an example (Fig. 95) but I can't understand how it is possible. I tried an example and my PWM signals (ex. on Fig. 95...
Posted on December 14, 2016 at 14:36hello,I'am use for a project the stm32f429. The interrupt handler must react so soon as possible.The stm32f429 interrupt responstime is 218ns.It's fast but not fast enough. I decided to make a new design with the...
Posted on November 29, 2016 at 23:27Greetings,I am trying to achieve the following with TIM1 and TIM1_CH1:1. Generate X number of PWM pulses after an event.2. Idle state of PWM output should be low.3. Pulse output should be high immediately after PW...
Posted on December 11, 2016 at 01:29After spending a lot of time with an STM32F469 discovery board I found that the touch screen doesn't have good linearity at all. You can't draw a straight line across the screen. If you for instance, start on th...
