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'...
Posted on March 15, 2017 at 22:47Hi,I have a STM32L0538 discovery board. I put the STM32Cube example code into it for Stop mode (no RTC) and it does not go into stop mode. It exits stop mode immediately. The only change I added was to toggle the ...
