Hey guys.Im using cubemx for i2c initiallization and i have a problem while using this HAL_I2C_Mem_Read_DMA function.When i call it in while(1) it works one time and after that it returns error or busy. while (1) { HAL_Delay(1000); HAL_I2C_Mem...
I need to modify ongoing the ic polarity of a timer input capture channel. I could act by changingchange TIM_CCER_CC1P directly, but i want to know if there is any other solution using HAL libraries. I'm using an STM32G0 mcThank you in advance.Enric...
In specific circunstances (power available, ...) I want to put the MCU in STOP2 mode. That decision is taken on a FreeRTOS task. I've tried some approaches but the MCU didn't stop at all. Is there any example available using FreeRTOS? The code I'm us...
Hello. I have STM3H723ZG Nucleo, by pulling boot pin high and providing reset condition, Nucleo stays in system bootloader mode. With Slave select low, I am send sync byte ( 0x5A) connections made over SPI3 port of STM32H7 controller form my Host con...
I was seeking option to run application without debug via UART, but dont found it yet. Can i download my FW to mcu from IDE without second program?
Hi all,I am just starting a new project with a STM32H7A3 processor and need to connect the system via USB as Device in CDC mode (Virtual COM Port). STM32CubeMX only allows to configure HS instead of FS. What has to be done to use the USB port in FS ...
Hi! i am using STM32F401CCU6 for BLDC/FOC motor control application.For foc application requirements, i need sampling 3 phase current in inject mode, vbus and motor temperature in regular mode.However, there is only 1 adc available for sampling. i tr...
Hi ALL,Can any please share a simple example application for STWIN STEVAL using FreeRTOS in Tickless Mode?I tried with few examples but I the current doesn't drops when MCU enters sleep mode. I am attaching modified Serial_DataLog example code which...
"HAL_I2C_MemTxCpltCallback" is not executed when using 'HAL_I2C_Mem_Read_DMA' in STM32F407VE MCU of STM32Cube_FW_F4_V1.26.0 while is executed normally in the old version STM32Cube_FW_F4_V1.25.0. It seems that it runs "I2C_MemoryTransmit_TXE_BTF" onc...
The MX_RTC_Init function resets the SSR register of the RTC, so with every power cycle there is a average error of 0.5s! That can accumulate to quite a huge error pretty quickly, if the device is switched on and off several times a day.Is this intend...
