Canbus Transmission and Receiving Problem

I have a project which is include Stm32f4 and CAN Trasceiver and I also using CAN Analysing to analyse the line. And I also have 120 Ohm.When I configure CAN1 and try to send CANBUS data with canheader.DLC = 8; canheader.IDE = CAN_ID_STD; canhead...

Is stm32 disco board supports CAN Communication?

Does Level 1 Read Protection mean I cannot backup my program from flash or have an IAP application?

I'm using a Nucleo F429ZI and I'm using a dual bank configuration. I'm trying to make sure I understand the read protection levels. If I want a feature that allows me to save a program written into the other bank (e.g. save it to a usb as back up), i...

STM32 USB HID host with CP2110 - problems with modyfing the code

Posted on April 30, 2018 at 23:15 Hi, I have a project where I need to communicate with CP2110 via USB (medical device having this interface). I am prototyping the application on STM32F746G-DISCO. I have started by running the Application exam...

how to terminate I2C master-receive transaction?

target CPU: STM32F427IGI set up STM32F427IG as master receiver via DMA. I wait on "DMA_GetFlagStatus(I2Cx_DMA_STREAM_RX, I2Cx_RX_DMA_TCFLAG" to figure out if I received what was sent.After running for 20 minutes or so, I2Cx_RX_DMA_TCFLAG flag does n...

Problem with HRTIM Nucleo-H743ZI2 Frequency of timer should be 480 MHz but it is still 240MHz

Hi I want to use the high resolution timer for a 10 bit resolution PWM output. Even the ioc file tells me that it turns on 480 MHz but it doesn't.I tested with a digital storage Oscilloscope the output of the PWMI used the basic configuration so i ha...

ADC conversion stops working with timer interrupt

Hi, I am new on mcus and STM32 board. Now I am stuck on a test project. I have a STM32F56ZG nucleo board and want to sample values from 4 ADC inputs; process them and then output the result on DAC channel 1. I am using DMA triggered by timer 6. The...
