|Subject:||Re: [Paparazzi-devel] ETS Airspeed Sensor with YAPA2 on I2C|
|Date:||Tue, 18 Jun 2013 22:44:49 +0200|
I have been trying to connect the ETS Airspeed Sensor through the I2C port of my YAPA2 with no luck. Can anyone please explain me the correct process to do it? I am no expert on electronics but I do have some working knowledge about it. Here are some questions that I have:
- I have connected 2 external pull-up resistors to the ETS sensor of 4.7k each the following way: 2 ends of the resistors to Ground and the other 2 ends to SDA and SCL respectively. This is in parallel. Am I using the correct values for the pull-up resistors? I have seen that when I connect the resistors to 5V instead of ground the YAPA stops working, the same happens when I connect resistors with other values.
- Do I need to solder anything else to the YAPA to get the I2C port working? Like other resistors for example? Please see the attached picture of my set up and let me know if there is anything wrong.
- I have been using the configuration that I found on the wiki (paparazzi.enac.fr/wiki/Module/Airspeed_ETS) on my airframe file for Measurement Only. So the only thing that I have added on my airframe file is the module airspeed_ets.xml and <define name="SENSOR_SYNC_SEND"/> as explained on the wiki. I do this and don't see the AIRSPEED_ETS lines on the log file. Do I need to add something else on my airframe file to get it to work?
