We are seeking an experienced developer to configure data exchange between a Jetson Nano and another device via the CAN bus, utilizing the RS485 CAN HAT. Documentation and examples for the RS485 CAN HAT for the Jetson Nano are available here: [login to view URL] Project Requirements: Data packets to be transmitted are split into frames of 8 bytes each, with the first 7 bytes of the frame encoded in ASCII. The last byte is an integer frame counter that does not convert to ASCII. A checksum is generated from the packet data and appended at the end of the packet using the following function: c Copy code uint16_t crc_chk_value(uint8_t *data, uint16_t size) { uint16_t crc = 0; while (size--) { crc ^= *data++; for (unsigned k = 0; k < 8; k++) crc = crc & 1 ? (crc >> 1) ^ 0xa001 : crc >> 1; } return crc; } If the last frame has free space, it is filled with zeros. An example of a packet structure and its breakdown into frames will be provided. Tasks: Receive a packet from the CAN bus. Verify the correctness of the checksum. If the checksum is correct, send a response to the CAN bus indicating "all is clear:crc", where crc is the control signature. The response packet must also be split into frames accordingly. Consider the necessity of data buffering due to the very short interval between packets. Skills Required: Embedded Systems C/C++ Programming Electrical Engineering Linux

As a freelancer with a diverse skill set that spans beyond just C/C++ programming to include Electrical Engineering, Linux and more, I believe I'm uniquely qualified for this project. Not only have I configured data exchange between multiple devices using the CAN bus in the past, but I also have hands-on experience with the Jetson Nano and the RS485 CAN HAT. By leveraging my understanding of these specific tools, I can seamlessly adapt the provided documentation and examples to suit your needs. Thanks to my background in Electrical Engineering and Embedded Systems, I am well-versed in packet management and know how to effectively handle checksum generation processes like the one you've defined. Plus, I appreciate that timing is crucial here given the short interval between packets, so adequate data buffering will be implemented to prevent loss or interference. Throughout our partnership, you can expect meticulous attention to detail in every task. Any incoming packet will be promptly received and its checksum rigorously verified before generating a correct response – "all is clear:crc", where 'crc' signifies the control signature. Finally, I bring strong communication skills and the ability to work within tight deadlines ensuring swift delivery of results without compromising their quality. Let's get started on integrating your devices proficiently!
