Summary of change:
'''Subpage of AfreshTiny''' '''Using round as AIM-display (eg. genboard users)''' '''Overwiev:''' Useful to get Lambda, EGT, RPM, MAP and other signals via serial port from the V3.3 ECU (or other device that sends AIM compatible data via serial/RS232 port) * Round (firmware since [http://www.vems.hu/download/round/ 2008-08] [http://www.vems.hu/files/MembersPage/MarcellGal/round/roundtest.zip temporary place]) can receive AIM (standard aim protocol 19200,8n1 rs232, 5bytes per packet) from PC or v3.x * the genboard can send realtime AIM data (from version 1.1.42) * '''Any channel sent by the sending device can be displayed on top or bottom display, with any scaling, offset and dot position''' * any number of rounds can get the data (eg. 1 genboard feeding 9 rounds displaying total 18 data). '''Displayed values''' Display state (mode) can be switched with the button (if button is enabled, see AfreshTiny/AnalogInput): 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, or, in future firmware, perhaps long keypress when peak values are displayed). Useful for MAP, RPM or any other channel. * the last received AIM data is displayed. If the display does not update, check the serial line and the sending device. You can use a switch in the serial line to intentionally cut the circuit at the desired time if you like. '''Connection''' * to PC: just connect Round's RS232 port to PC's com port * to ECU: connect RS232,pin 2(tx) ECU side to RS232,pin 3(rx) ROUND side ** if you use more than one ROUND the rx pins are common '''ECU''' * v3 firmware must be at version '''1.1.42''' or later * to enable with VemsTune (must be newer than 2008-09-30) (or Megatune): ** Extras menu / LCD Settings / AIM Enable http://www.vems.hu/files/Display/Round/v3_aim_settings.JPG * to enable in config files: set lcd_c0 bit2 * ECU can't connect to PC and Round at the same time '''Setting the round''' Round firmware must be newer than 2008-08 with VemsTune (or Megatune): * first set the default device to Round at Preferences / Default Device Config http://www.vems.hu/files/Display/Round/VT_def_dev.JPG ** '''don't forget to restart VemsTune after set it''' * after restart you can see the Round specific menus: http://www.vems.hu/files/Display/Round/round_menu.JPG * AIM enable: ** in Settings menu / Display Demo ** the AIM can enable for the top segment if TOP segment0 bits=165 ** the AIM can enable for the bottom segment if Bottom segment3 bits=165 ** The '''AIM mode for the TOP and Bottom display can be enabled individually''' (with segment0=165(0xA5) and segment3=165(0xA5) 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). http://www.vems.hu/files/Display/Round/round_aim_ena.JPG * AIM settings: ** in Settings menu / AIM settings top (AIM settings bottom is the same) ** 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) ** Channel x num: there you can choose the number what to show as Tx ** Channel x mul: the data from ECU has different format, with this value you can multiplicate ( 0..2X ) ** Channel x add: the data from ECU has different format, with this value you can add offset *** Zero means 8192 so you can incrase or decrase value with 8192 ** Channel x dot: the data from ECU has different format, with this value you choose where to show the dot http://www.vems.hu/files/Display/Round/round_aim_settings.JPG ** Aim realtime data types and numbers: ***http://www.vems.hu/files/MembersPage/NanassyPeter/AIM_support/AIM-ECU%20protocol.pdf '''Using:''' * After power up the well configured ECU will send the AIM data and the connected Rounds will show as it configured * The switch on the Round will change the 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. ---- Feedback from round => genboard (useful button for launch or table-config-switch?) is not planned in 2008. I want to try use AIM for project with more budget. But now what me prevent from it is CLT temperature limit of 101-102C. What about this problem? MembersPage/GintsK

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.
