Trigger Input

Hi, I am currently trying to timestamp an event on a gpio pin using a navspak (glonass,baidu and mini version). The problem is that I would ideally require a callback (basically push I assume) on _both_ edges. Is there any way to get this done (via multiple callbacks, logical or between rising/falling edge flag)? Also: am I blind or does the mini lack the gpio10 required for timestamping? (is there a way to remap it to something else?) Thanks in advance, Markus

[Problem] Adafruit BNO055 9-DOF

Hi everyone !  I am trying to get some infos from my Adafruit 9-DOF BNO055 with a navspark-GL, but I fail.. I have followed this instructions here: http://www.navspark.com.tw/blog/i2c-improvement to port the library for navspark The compilation and the update are ok. My code -> code_BNO055 But I get nothing from my sensor... If you have any ideas ? Thanks in advance

I2C Improvement

Along with latest Windows and Linux Board Manager support update, the NavSpark I2C library has been improved to allow easier adoption of other vendor's example code when using their break board.

Using Adafruit's 10DOF break board and BNO055 break board, below list modification guidelines needed to make them work with NavSpark:

1. Change all #include <Wire.h> to #include <TwoWire.h>     click below image to zoom…

"There is only GPIO10 pin that supports time-stamping. It can be configured to be rising-edge triggered or falling-edge triggered, but not on both edges. To trigger on both edge, you’ll need to implement a small circuit that generates two pulses from…"

"Thanks Jason, that explains the difference in start-up time and location stability. Every restart of your firmware is in fact a warm start. I didn't know that.
I did have the impression that your firmware resulted in a more stable solution. But that…"
