Summary of change:
'''Subpage of AfreshTiny''' '''Using round as AIM-display (eg. genboard users)''' * connection * v3 firmware ** version ** configuration lcd_c0 bit2=1 * round firmware ** version There exists configuration (aim channel and Ax+B linear transformation) for 4 top (T0,T1,T2,T3), and 4 bottom values (B0,B1,B2,B3). '''8 display modes (disp_state variable)''' ** 0..3: T0/B0 T1/B1 T2/B2 T3/B3 ('''displaying "pairs"''') ** 4: display '''peak value''' of T0 and B0: PT0/PB0 ** 5..7: T1/B0 T2/B0 T3/B0 (displaying '''B0 with Tx''') As you see, one bottom configuration (B0) can be displayed with any of the 4 TOP configurations. The '''AIM mode for the TOP and Bottom display can be enabled individually''' (with segment0=A5 and segment3=A5 respectively). If only the bottom is in AIM mode, and the top display not in AIM mode, eg. segment0=00, than normal value is displayed (lambda / AFR in this case, measured by round itself). ---- '''to get Lambda, EGT, RPM, MAP and other signals via serial port from the V3.3 ecu''' Round (firmware since 2008-08) can now receive AIM (protocol 19200,8n1 rs232, standard aim protocol, 5bytes per packet) from PC or v3.x * the genboard (firmware) side is under testing. It requires genboard to send in 19200 baud (likely megatune will use the same baudrate) * Any channel defined in the AIM protocol can be displayed on top or bottom display, with any scaling, offset and dot position * button can be used to switch display state (mode): 7 sets of top/bottom values can be configured * the 8th mode is the peak value remembered for top/0 bottom/0 (peak value resets at powerup). Useful for MAP, RPM or any other channel. * any number of rounds can get the data (eg. 1 genboard feeding 9 rounds displaying total 18 data). Feedback from round => genboard (useful button for launch or table-config-switch?) is not planned in 2008.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
