Field Documentation

◆ checksum

uint8_t ec_host_cmd_request_header::checksum

Checksum of response and data; sum of all bytes including checksum. Should total to 0.

◆ cmd_id

uint16_t ec_host_cmd_request_header::cmd_id

Id of command that is being sent.

◆ cmd_ver

uint8_t ec_host_cmd_request_header::cmd_ver

Version of the specific cmd_id being requested. Valid versions start at 0.

◆ data_len

uint16_t ec_host_cmd_request_header::data_len

Length of data which follows this header.

◆ prtcl_ver

uint8_t ec_host_cmd_request_header::prtcl_ver

Should be 3. The EC will return EC_HOST_CMD_INVALID_HEADER if it receives a header with a version it doesn't know how to parse.

◆ reserved

uint8_t ec_host_cmd_request_header::reserved

Unused byte in current protocol version; set to 0.
