with all your help I tried to change multichannel using DMA but I cant able to read the values can anyone please help ADC_HandleTypeDef hadc1; DMA_HandleTypeDef hdma_adc1; UART_HandleTypeDef huart2; /* USER CODE BEGIN PV */ uint16_t mains=0; uint16...
HeyI try to work with the Timer1 in interrupt mode. I saw that Timer1 is belong to APB2 BUS. I configure my source clock to the TIMER1 to 96MHz (picture1),at APB2 Timer Clocks But I saw that the frequency is match to the number on APB2 Peripheral clo...
Hi CommunityI could use some help regarding UART on the "Bluepill" board so I can get my night sleep back againI'm working on a small project where I'm creating some interrupt driven bit frames on 16 outputs. Each frame is 16mSec long and consists of...
Hello Team,I am currently working on Ethernet to send data to server. I have tested the Ethernet and have sent data to server via "TCP" but my requirement is to send data using "Post" method of any URL.Do you have any example code or can you provide ...
Hello,I am experiencing counting errors (specifically overflow counting errors) on LPTIM1.A bit of context first: the goal is to use the LPTIM1 to count pulses which are first treated by the COMP1 (to convert the input signal into an all-or-nothing s...
Using F401 ADC continuous conversion and DMA for multiple channels.I have pins A0-7, B1, PC0-5 running conversions. For consecutive pins in a group (A0-7) (C0-5), the final pin in use always has a different offset error to the rest. Note this actuall...
KeilA USB drive is connected to the STM32F407VGT6.The USBH_UserProcess function is located in the FatFs library for USB drives.I wrote this code in the USBH_UserProcess function: uint8_t Array[1000]={0}; for(int i=0; i<1000;i++) { printf("%d\n", Arra...
Hi, I am currently using two SMT32F207 for I2C transmission (MASTER writes SLAVE). Below is my configuration and waveform diagram.The problem currently encountered is that once the bit changes from 1 to 0 (HIGH to LOW)The transmission of SCL and SDA ...
I use two Nucleo-G0B1RE to communicate with each other using UART. UART5 of the master board is connected with UART1 of the slave board and both of the UARTs use DMA receive. When I first pressed the reset button of the slave board and then the maste...
This is not description of normal ADC operation, but experiment aimed at revealing of details of the ADC internals, inspired by this thread.I wrote a simple program for a 'F407-Disco (in attachment), which performs a 2-step sequence of ADC conversion...
