Resolved! Best ADC accuracy that can be obtained with a Nucleo board or similar.
I am using STM32F407 and STM32F767ZI on Nucleo and other boards. My configuration is a simple potentiometer as voltage divider (200K or 1K) to generate the analog input voltage.Even with stable voltage on the ADC input (verified with my fluke 117 & ...
Resolved! Does the STM32F411CE support CANbus?
I don't find any information about what pins to use for CAN, so I'm guessing it doesn't, but I'd like to be sure. I have a "blackpill v3" board.If not, what is a commonly used CAN controller IC?
UART RX Busy Flag Constantly Set
I had a project I was using on the L053 Discovery Board (STM32L053C8T6 micro) that was receiving some data from the UART that was working fine. Built my own board using a different L0 part (STM32L010F4P6). When I try to run this same project, the UAR...
why I can only run *(__IO uint32_t *)(0x6C000000) = data; from main.c
I am trying to use FMC and I am using *(__IO uint32_t *)(0x6C000000) = datato send the databut it only works from main.c I had bunch libraries included in other files too.when I try to create new c file and put there I am getting errors. Can anybody ...
IAP with UART
Hello everyone,Here i am trying to implement IAP using UART in stm32 and successfully implemented also but using YMODEM but i want to use only UART without Ymodem protocol can anyone help to create a function or file to receive .bin file from UART an...
STM32F103 and I2C TX using DMA, byte array issue
Hello, i have the following setup code for i2c and DMA, where i use i2c1 to send some buffer data to a display. DMA_DeInit(DMA1_Channel6); DMA_InitStructure.DMA_BufferSize = DMA_I2C_BUFFER_SIZE;//BufferSize; DMA_InitStructure.DMA...
Usage of TIMER2 on STM32F103C8 for encoder & pwm generation
Hello,i am using on stm32f103 timer2 where channel1 & channel2 are used as input capture for reading a external rotary encoder.Since my design is quite tight ( using almost all pins available), i need to generate a PWM for an external LCD backlight ...
how to get 50 % duty cycle with complementry pulse
i want to generate 50 % duty cycle at freuency (100khz-200 KHz), but i am not getting 50% , i am getting 33-34% duty cycle.this duty cycle change when the frequency change.
STM32H743 - Problem with DAC DMA and SPI Receive DMA when adding the FreeRTos.
HiI am working with a project were i am using two DAC channels and a SPI port set to receive mode and I want to use these in DMA mode. I am using the CubeMX to set this up and if I only setup the DAC and SPI in DMA mode, then it works as it should, w...
