pub const fn header(chain: Chain, opcode: u8) -> [u8; 2]Expand description
The two bytes every frame to a front end starts with.
A command is this header and then its payload. A read sends the same frame and takes the
answer from where the payload would have been, which is why HEADER_LEN is what a
reader skips.
§Arguments
chain- the chain the front end is on.opcode- the command.
§Returns
The header.
§Examples
use pamoja_radios::sx1302::sx1250::{header, OP_SET_RF_FREQUENCY};
use pamoja_radios::sx1302::tx::Chain;
assert_eq!(header(Chain::A, OP_SET_RF_FREQUENCY), [0x01, 0x86]);
