Also, I see three different possible design approaches for this project. It's a fairly simple control loop that we're developing. The 3 options seem to be:. I don't think we need an RTOS. Do you know if the addresses and ports are the same between the F3 and F4? We will be building our own trancievers. With board-to-board you'd need at minimum a diode arrangement as CAN RX needs to see TX data to confirm signal has been placed on bus, and you'd need a responding device to acknowledge receptions.

I'm getting closer. I only have a scope on the pin outs and don't have a transceiver or 2nd CAN device yet. The following line overwrites the Timeout parameter that is passed in:. Before that line is executed the Timeout parameter is 10 the value passed in but after that line executes, it is hammered and has a value of 0x The value of. Maybe the problem is that there isn't a real CAN bus yet.?.

I hope adding the transceivers will get things talking. The AF mux maps a specific peripheral to a specific pin.Cookie Notice.

STM32 CAN Example

Cookie Policy. Privacy Preference Centre. Can someone please help me!! But i am unable to receive any data on my receiver. Please be aware that the forum was just ported to a new platform, old users and posts may not be responsive. Ask yourself if framing a new question, with complete details of the part you are using and the code and configuration you have now might be more productive?

Thanks for your advice, if you know something about these libraries would be helpful, so if you can help me my code is:.

But when am transmitting data on CAN2 am not able to receive any data on bus. Am getting bit stuff error on PCAN viewer. Though its not a slave on CAN network.

I have already verified my tranceiver using CAN1 ,So am sure about the hardware setup. Thanks for the reply. I could see the Tx starting pulse on CAN bus. Looks fine. I don't like what you did with the Filter ID, but don't know if that impacts the situation. Seems like an issue at the HAL level, you'd need to dig into that a bit, not really something I can expend resources on.

All forums and questions are now archived. To start a new conversation or read the latest updates go to forums. I'm actually working on the backend and hardware of that project and I'm tight on time and grew frustrated at integrating the CAN bus functionality on the mbed platform.

I'm actually having the CAN working on the IAR studio, but I need it to work under the mbed platform too to make it easy for all the users. Ugly but working. I need: functions to read the buffer in and send messages, functions to initialize the hw and filters, a way of handling interrupts and errors. If I am bored during holidays I might have a look. Please let me know how it works.

I tried a lot to make your library work earlier but with no success before this update - I'll try it tomorrow. I'm still trying to get it working, the CAN is not initializing. Hi Mastro, I'm glad that I was able to help you. That's good enough for me. We are building here open source so just forget about any PP. By the way, you have a nice and challenging project so keep on and good luck.

Application Presentation 1.STM32F3 Discovery board is a great device for studying robotics and mobile automotive tools. This board is good enough to develop a flight-controller or a fancy smart robot.

This evaluation board has several LEDs. We will use port E pin 8 for blue LED blinking. It seems to be an ordinary task. In fact it includes some complex routines that are not visible at the first sight.

You might know that every program starts at main function. In fact before the main function is called the start up code initializes MCU, interrupt table and configures crystal oscillator.

The source code can be compiled, linked and the firmware is ready to be downloaded into the STM32F3 board. This multi-layered bit bus is composed of several masters and slaves. MCU core controls the data flow over the buses and firmware developer does not need to know its internals. But it is important to understand how to configure peripheral devices connected to this bus. I should mention that APB1 is a slow bus.

Its speed is limited to 36MHz. This picture gives an understanding of how the bus multiplexer is designed. Some peripheral units can work autonomous with each other. The text version of the peripherals interconnect matrix can be found in Table 22 of the Reference Manual pageCh. Knowing these interconnections allows the following benefits:.

Tutorial: Getting started with STM32F3 Discovery board

Interconnection details are described in different sections of the Reference Manual. I think we should keep in mind this feature and use it when possible to improve performance. Although the STM32 is a 3. Every port contains 16 pins Port pins can be individually configured. I should say a few words about Alternate function AF.

A pin can behave as a clock line or a data line for specific communication protocol. In the User manual you can find table 6 where all functions are listed. The hardware basic structure of a port pin is shown in the figure. There are three important built-in units:. For example, a typical hardware I2C connection between the host master and the slave target requires pull-up resistors.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
