-- Multi buffer for HoTT description
|
|
-- To start operation:
|
|
-- Write "HoTT" at address 0..3
|
|
-- Write 0xFF at address 4 will request the buffer to be cleared
|
|
-- Write 0xDF at address 5
|
|
-- Read buffer from address 6 access the RX text for 168 bytes, 21 caracters
|
|
-- by 8 lines
|
|
-- Write at address 5 sends an order to the RX: 0xDF=start, 0xD7=prev page,
|
|
-- 0xDE=next page, 0xD9=enter, 0xDD=next or 0xDB=prev
|
|
-- Write at address 4 the value 0xFF will request the buffer to be cleared
|
|
-- !! Before exiting the script must write 0 at address 0 for normal operation !!
