Missing is: - copy destination address - copy source address - set frame type - calculate and add CRC32 checksum firmware: Rename frame to payload 2024-06-01T10:08:57Z xengineering me@xengineering.eu 2024-06-01T10:08:57Z urn:sha1:010cf768c20c71603172ae4c300ce3d571863141 This array does not really contain the whole frame. firmware: Fix missing include guards 2024-06-01T10:07:24Z xengineering me@xengineering.eu 2024-06-01T10:07:24Z urn:sha1:71f05dc68f31e01b01bbd47d1d7454719b19cce4 firmware: Assert presence of EUI-64 MAC address 2024-06-01T10:04:57Z xengineering me@xengineering.eu 2024-06-01T09:17:50Z urn:sha1:df38994a4a784cc7b794c3f2a3c7f08172ef51ad Without that address comunication is not possible. firmware: Separate data link related code 2024-06-01T08:25:12Z xengineering me@xengineering.eu 2024-05-31T08:33:56Z urn:sha1:ff3fa235236f2d6d92f7869fb4f55e3655b0502a firmware: Add end and escape byte to UART output 2024-05-31T08:09:55Z xengineering me@xengineering.eu 2024-05-31T08:09:55Z urn:sha1:bb029aacf08983ad6c1a6360d988e89394fc4d85 These special bytes of the Serial Line Internet Protocol are contained inside the payload to validate that the escaping is working correctly. firmware: Implement send_frame() 2024-05-30T20:45:41Z xengineering me@xengineering.eu 2024-05-30T20:45:41Z urn:sha1:b1206aaa1f6bc4a04509149024402dea9da12e27 This transmits a frame via the Serial Line Internet Protocol (SLIP). firmware: Rename from uid64 to eui64 2024-05-30T20:12:34Z xengineering me@xengineering.eu 2024-05-30T20:06:31Z urn:sha1:b8147bcba2e8dfef419ba14053285bc9750dc319 The term EUI-64 is more commonly known (see Wikipedia about MAC addresses [1]). The term UID-64 was introduced because of ST documentation.
