Member Data Documentation

◆ ecuResetScheduled

uint8_t UDSServer_t::ecuResetScheduled

nonzero indicates that an ECUReset has been scheduled

Definition at line 932 of file iso14229.h.

◆ ecuResetTimer

uint32_t UDSServer_t::ecuResetTimer

for delaying resetting until a response has been sent

Definition at line 933 of file iso14229.h.

◆ fn

UDSErr_t(*) UDSServer_t::fn(struct UDSServer *srv, UDSEvent_t event, void *arg)

callback function

Definition at line 922 of file iso14229.h.

◆ fn_data

void* UDSServer_t::fn_data

◆ notReadyToReceive

bool UDSServer_t::notReadyToReceive

not ready to receive (Table A.1 0x78)
not accepting request messages and not sending responses (9.3.1)

when this variable is set to true, incoming ISO-TP data will not be processed. incoming ISO-TP data will not be processed

Definition at line 967 of file iso14229.h.

UDSReq_t UDSServer_t::r

request context

Definition at line 969 of file iso14229.h.
