I added a constant to SLIP for ISR. The user will have a choice. each
is good and bad in their own way:
1. The ISR only gets characters and puts them in the buffer. It is up
to the user to check if there is a packet available. This is the
default setting. Here's an example:
procedure slip_received_packet_callback(byte in packet_size) is
for packet_size loop -- for each byte in packet
serial_hw_data = slip_rx_buffer -- do something with the packet
data
end loop
end procedure
-- your main loop
forever loop
if slip_packet_available then -- if a packet is available
slip_received_packet_callback(slip_packet_size_buffer)
end if
-- do other stuff here
end loop
2. The ISR will receive characters and when a full packet is received,
it will run the callback within the ISR:
procedure slip_received_packet_callback(byte in packet_size) is
for packet_size loop -- for each byte in packet
serial_hw_data = slip_rx_buffer -- do something with the packet
data
end loop
end procedure
-- your main loop
forever loop
-- do other stuff here
end loop
--
