Re: [Paparazzi-devel] YAPA2 First Time

[Christophe De Wagter]

Unless you have some weird issue with I2C conflicting with SPI-Slave again, I think it is an XBee problem. I've seen that before. XBee Ground is set to talk to XBee 1. And then XBee ground suddenly must talk to XBee 2. So you set them to broadcast. And then the data arrives until the ground modem uploads some message (which happens automatically with the PING message every X seconds).

I recommend using xbee_api instead or use 2 ground modems and configure all 4 xbee's 1 <-> 1 filling the destination addresses for each.

The only power problem I know of on all tiny2/twog/yapa boards is that the enable pin on the PTH08080 module is very high impedance, so when you touch it with your finger when also touching ground, you can actually switch off the power.

Hello Christoph,

Thanks for your reply. I am using the Xbees on transparent mode. I also measured 5V at the output of the switch but I am not sure where to measure the 3.3V for the processor. I measured 3.24V at the Boot and 3.28V at the ADC1/2 ports. I don't understand what is going on because I have the exact same configuration and connections in another YAPA2 that is working fine. 

I am using a 11.1V LiPo battery plugged to BAT. My best guess is that I have a hardware problem, any ideas on how can I solve this?

Best Regards,

If you are using xbee's, this behavior has been reported before when the adresses do not match. Are you using xbee-api mode or transparent? 

If it would be any hardware related issue, then it is a power-supply problem. So how did you power your board? Can you measure the 5V output of thee  switching regulator and 3.3V for the processor?

Hello all,


I am trying put to work another new YAPA2 that I have and it is giving me some trouble. The status LED3 (green) blinks for a second and then it stops and I get on the mode section of the GCS a FAIL status. I wonder if there is anything else I that I need to do to this new YAPA2 board before put it to work or it is just damaged?


Best Regards,
Jorge
