Real time buffer commands

Command

Response

4/0 (Buffer info)

0x04 | 0x00

status | size*2 | write position*2

size: Ring buffer size (90), write position: position next to be written

Command

Response

4/1 (Find oldest)

0x04 | 0x01

status | read position*2 | lap counter

Read position: position where is oldest data,
lap counter: how many times ring buffer has rolled over (0..255)

Command

Response

4/2 (Find newest)

0x04 | 0x02

status | read position*2 | lap counter

Read position: position where is newest data,
lap counter: how many times ring buffer has rolled over (0..255)

Command

Response

4/3 (Read buffer with
index)

0x04 | 0x03 | index*2

status | index*2 | lap counter |
timestamp*4 | id*2 | type | data*n

index: buffer read position
lap counter: how many times ring buffer has rolled over (0..255)
timestamp: 4-byte timestamp, see p. 26
id: data origin
type: 32 (STRUCT), see p. 21

Command

Response

4/4 (Read next)

0x04 | 0x04

As in command 4/3

In case of no new data returns only status byte

Command

Response

4/5 (Reread last)

0x04 | 0x05

As in command 4/3

Returns data which was read last. This has its uses when serial communication error happens.

Flash commands

Command

Response

4/16 (Read ﬂ ash)

0x04 | 0x10 | address*4 | count

status | data*count

address: ﬂ ash address, count: data byte count, data: see page 26

Command

Response

4/17 (Find time)

0x04 | 0x11 | timestamp*4

status | address*4 | timestamp*4

timestamp: 4-byte timestamp, see p. 26, address: memory address where is data which is just
next (newer) from given timestamp, response timestamp: timestamp of the found data
