I have a program for which I would like to enable link-time optimization. However, once I pass the -flto flag to the compiler and linker, I get two linker errors, one complaining about multiple definition of _exit and undefined reference to _sbrk. I...
I did set up a basic STM32_CubeIDE project with 3 USARTs.When the PB11 Pin (USART3 RX) is connected to the communication signal, the signal is corrupted to a high signal level of 2.6V and a low signal level of 1.7V. This also happens also, when I con...
This is my code.GPIO_PinState boButton_state ;printf (" Hello �?� Cruel �?� World \n"); while (1){boButton_state = HAL_GPIO_ReadPin ( B1_GPIO_Port , B1_Pin ); HAL_GPIO_WritePin ( LD6_GPIO_Port , LD6_Pin , boButton_state );HAL_GPIO_TogglePin ( LD3_GPI...
I need to dynamically change waveforms on a PWM output on an STMF030 MCU.See it as a poor man's alternative to a signal generator using a DAC.It will be used to generate modulated audio waveforms.I am using DMA to lookup (a sine) waveform via a circu...
I want to know: how many analog input pins are there in each board. which board is good at taking data from sensors continuously which would be better for USB communication with raspberry pi or is there some other boards which is good at taking analo...
I am using STM32L476 Nucleo board and cubemx. I want to use Output compare channel 1 for timeout of 2ms. i have configure the timer but timer is not giving interrupt for Output compare. i am getting interrupt for period i gives for timer. but not for...
Hi, I am a beginner on STM32. I got assigned into a project where i'll use some MCUs from STM32 family (F103VE, F103CT, F303KB) to build a sensor grabber to get data from OBD-II of a vehicle and some sensor modules (Vibration, BMP280, IMU). My F103VE...
End result: same SPI channel different devices accessed individually.
I need to use all four Capture-Compare interrupts to use multiple timeouts for TIM5 on STM32F427. It is a 32-bit timer.The problem I am running into is that the interrupt flags are constantly high (e.g. CC4IF,CC3IF,etc.) . As long as only one CC-inte...
