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...

Posted on March 17, 2017 at 07:44Hello everyone,I am using stm32f4 discovery board. i am accessing on board digital mic with I2S protocol and decode data using PDM to PCM library from st.Now i want to use one more mic for stereo audio (one mic for l...
Posted on March 17, 2017 at 02:58I am sure this has been asked 1000 times, but I still cannot get the results I need. I am trying to generate a 12800000 clock output on TIM9 with a 50% duty cycle. I have looked at the code examples. I have the AP...
Posted on March 17, 2017 at 06:28In STM32Cube_FW_F4_V1.15.0, I find a new function: HAL_GetUID(), the brief description of this function is: Return the unique device identifier (UID based on 96 bits). I wonder, how 'unique' of this ID, unique in ST'...
