I understand that, in order to put the F750 to sleep AND reduce power supply heat during sleep, we should use:HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);WFI();But I have not read what happens when the CPU is not sleeping (du...
Hi :) I am trying to play audio from an SD card to the built-in DAC of my Nucleo-F446RE.I am using DMA, and one buffer of 10240 size, which I want to update continuously using the Transfer Complete / Half Complete callbacks.The code is quite simple, ...
HiI am currently trying to create a delay function on my STM32F407 discovery board using a free running timer (I used TIM6 for this purpose). I set my counter clock frequency as high as possible and my max counter value to 0xFFFF. Based on my calcula...
I want to use STM32 as ECU(VCU) for my formula student Electric Vehicle. I am using Orion BMS and DTI motor controller.
I would like to call C++ function from C file. How to do that.I have C++ function call Cpp_func() in test.cpp file. In test.h file, I declare as extern "C" Cpp_func(void); This gives me error that expected identifier.
Hi!I am struggling while using the DAC of my STM32F446RE with 12 bits resolution. I want to output the value of a variable (val_av) after some calculations on the STM and collect it with a data logger. At the beginning, I had a data logger with digit...
Hello,does anyone use ZLIb in their STM32?I having some problems and I wish for help...Thanks.
I want to drive simple buzzer with HAL library.I did this with mbed library and I played simple pirates of the caribbean melody.My mbed code like this :#include "mbed.h" #define NOTE_C4 262 //Defining note frequency #define NOTE_D4 294 #define ...
I need to support UK, US, French and German keyboards in my application. US/UK are working fine. German looks like a pain with AltGR needed for simple characters like @[]{} (How do Germans program in C without going mad?). If anyone has some code and...
@For a few days I'm trying to get the correct answer from the PS2 PAD on the STM32F103 Bluepil. I Used SPI2 with clock frequency is set to 36MHz (APB1) SPI prescaler 256 configuration which gives me 140KHz (or KBits / s). The first bit is taken from ...
