Posted on December 18, 2016 at 15:11Hello all! How's this for my very first question I purchased a 3d Printer on clearance with a tag that says Does not Start up. No warranty. I was ok with that. As I'm a developer and a hardware hacker I knew I...
Posted on March 16, 2017 at 20:16I have attempted to set up timer 4 channel 1 for input capture but unsuccessfully. The scope indicates that my 1KHz, 3vdc, 35 uSec pulses are making it to PD12 (TIM4, ch 1). However, CC1IF is never set. Although chan...
Posted on March 17, 2017 at 13:29Hello, I'm going to use the 'Character match interrupt' to identify the end (\n) of the message received from an USART. (on an STM32L4 Series ).Since I am quite new to this world, I did various tests, but I cou...
Posted on March 17, 2017 at 02:07I test audio recorder/player on STM32F746-DISCO board.So, WM8944(codec) drive speaker(2W) out.But, TFT-LCD was break sometimes at full volume level.So, I think LDO Power is lack on STM32F746-DISCO board.
Posted on March 17, 2017 at 07:39I used TIM1_channel 1 and channel 3 .TIM3 use ADC triigger.so I want to update TIM1 duty cylce.I wrote code below.HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_1); __HAL_TIM_SET_COMPARE(&htim1,TIM_CHANNEL_1,detact_pulse);HAL...
