Dear friends,I have been using the STM32H743ZI in three phase power supply project and the controller is responsible for the zero crossing detection of the three phases. To do this I use PB0, PB1,PB2 set up as EXTI inputs 0,1,2. Mains frequency is 50...
I am making L031K6 mcu sensor. This sensor regulary sense some adc data then send the data to Android device by BLE.and I am using HAL_UART_Transmit() for sending message to android by BLE.but when android is missing, my MCU runs bad. so I guess HAL_...
Wants to stored that string in non-erasable memory location . when I off the power supply it should be present .also I want to change that string at running the programI have search on netAny help will be highly appreciated.
Hi, I would like to read AT Command responses back from my ESP2866, as I want to check whether the response is "OK" or "Error". I made a function as below but it doesn't work properly.The plan is to send AT commands on USART3 and right after that, re...
dear all,My question is about the Cortex-M0+ options that were selected for the STM32G0 products (table 1-1 from the ARM Cortex-M0+ TRM). I can hardly find them in the STM32G0 RM and DS. Do you know where I can find the answer ?Regards
HW situation is:I2C2_SCL on PB10 (pin L4)I2C2_SDA on PB11 (pin M4)Both have a pull-up resistor of 18K.The sensor attached to these lines is removed, so nothing is connected.This is not a dev-board but our own design.I have generated code through STMc...
Hi ST,I'm trying to enable PWM mode of Timer14 (STM32F030C8T6). But the output is always LOW. I do all the steps described in the ST Periferal Library. Also I successfully run the similar code on STM32F103xxxx. Could you check this simple code? Is th...
We are using the STM32H745 dual core MCU in the we are trying read and write the data using DMA. When we are trying to receive the data that controller going to the DMA error call back function ,for this what may be the issue . And also in interrupt ...
Hello,I'm using STM32f411RE with ADC and I would like to know why when the sampling time is less than 84, I don't find by calculation the same expected conversion frequency/time?My calculation is Tconv = (3+12)/210000Hz = 714 ns so a frequency of 1.4...
