[Paparazzi-devel] GASoline sensor

[Eduardo lavratti]

Well, my gasoline sensor come today.
The sensor output 10000 impulse/liter in TTL level.

Some time ago i asked about how can i read the sensor that output pulses and somebody pointed me to XTEND_RSSi and EXTERNAL TRIGGER but this 2 modules are for read a pulse width.

I can use the external_trigger module with some modification but its waste of code and capture module.

I need a simple external interrupt.
Here are my question: can i use an arch code like the code used for MAX1168 EOC interrupt ?

My idea is to use the DRDY pin (TWOG BOARD) connected to sensor output so i can receive the pulses as interrupt.

When interrupt occur i increment a counter and read the counter in module periodic.

Each pulse is equal to 1/10000liter so i will integrate to get how much gasoline the motor used.

Can some one talk about ? its possible with eint0 ?
