Summary of change:
I'd like to gather some data from the ECU via a serial connection. ---- '''AIM''' (broadcast format) * Enable in VEMS ECU configuration * See BroadcastDatastreamAim ** GenBoard/UnderDevelopment/FirmwareChanges 1.2.35 fw entry * via 1st serial is easier (also works with old fw, but not available when VemsTune is connected: may or may not be acceptable depending on the application). 5 byte packets, (aligned to 0xA3, although A3 is weirdly not the first byte, see the AIM-serial/RS232 specs) ---- '''Triggerframe format''' is supported * SIPR ("Mas") might not be supported in recent firmwares. * '''TF(A0) == $7e$a0$bf$38$7e ''' => response 0x20 type, and the beginning of the frame are the (appr 76byte) runtime values exactly same as in comm.c and offsets specified in vemstune config/*.ini (vemstune displays all runtime data from these). Can you provide an example in C? Sending a TF (send+receive) example in Perl via other channel.
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.
