I’m trying to use GPIO API.
cdef fragment:
requires:
{
api:
{
NReset = le_gpio.api
}
}
adef fragment:
bindings:
{
fx30.App.NReset -> gpioService.le_gpioPin6
}
Compilation output:
mkapp -t wp85 -s /home/tm/dev/sv/legato-16.10.1//components fx30.adef
[2/7] Generating IPC interface code

ninja: build stopped: subcommand failed.
After some research the problem is related to:
EVENT ChangeEvent
(
Edge trigger IN, ///< Change(s) that should trigger the callback to be called.
ChangeCallback handler, ///< The callback function.
int32 sampleMs ///< If not interrupt capable, sample the input this often (ms).
);
in le_gpio.api.
Script codeGen.py assumes last param of EVENT is handler.
# --------------------------------------------------------------------------------------------------
# This will generate the code to request the server to register a client's event handler.
# --------------------------------------------------------------------------------------------------
def WriteClientAddEventFunction(clientFile, apiName, addFunc):
WriteClientFunctionPreamble(clientFile, addFunc)
# First off, pack up the normal parameters for this function. We separate out the last one
# because we deal with the event handler object specially.
basicParams = addFunc.parmList[: -1]
handlerParam = addFunc.parmList[-1]
Not sure where the mistake is. Error in codeGen.py or le_gpio.api? Anyway, I replaced order of parameters in le_gpio.api and it compiles, but I guess I won’t be able to register event handler due to mismatch.
