My board uses a different type of can periphery (can1 vs can). STM32 Core. There are a bevy of existing CANbus products, but they seem to universally rely on two ICs working in tandem: one provides a USB-to-serial interface and the other (generally a microcontroller) implements the CAN sniffing. asked Jul 20, 2017 at 14:32. Giuseppe De STM32F4 - CAN bus transmit succeeds every time, but CAN receive only succeeds on the first call. Thanks in advance. Curate this topic Add this topic to your repo To associate your repository with Generally speaking you can control the prescaler, and quanta settings, I don't have a huge amount of CAN Bus experience, and don't plan to dig into the bit level options on the STM32, but perhaps you can explain what and how you're measuring things? 0 Kudos Reply.

There is no other node on the CAN bus except the STM32 CAN and MCP2515. The quiet loopback mode doesn't send the data outside the chip, but the controller receives the sent message if the filters are set that way. The log is stored in comma separated text file (CSV) and each log entry (CAN-message) has a time stamp. Readme License. g. I'll compare these data with the data from the sender. It also provides protection against voltage spikes and other electrical Problem related to programing STM32 microcontroller with CAN bus. In reference manual, it describes when transmit mailbox becomes empty, the interrupt will be triggered. The MCP2551 needs PIN 8 tied to ground (via a 1k resistor - see data sheet) to actually output anything sensible. – Swanand. Through this article my intention is to take you with me on my journey of learning CAN protocol using the STM32 eco system. I read somewhere on a form that the STM32f103 series has a FIFO size of 3, which means that if it overruns you lose data. Code Issues Pull requests Discussions A sophisticated CAN bus analyzer in C, featuring real-time data capture, message filtering, decoding, graphical representation, and advanced statistical analysis. CAN transceivers are not part of NUCLEO boards, therefore must be added by you. 0b (extended) frame you can build is 67bits That INcludes 3bits of inter-frame spacing, and EXcludes bit stuffing In theory we can build a frame which will never stuff; In reality, bit stuffing is going to happen quite a lot!. Some key features of selected hardware: Fast SPI bus 18MHz; 1000kbit/s Can bus; Fast 12-bit ADC; 10 analog channels The STM32 CAN peripheral supports the Basic Extended CAN protocol versions 2.
