"I got the 2 GPS working. The only way I was able to use LEA6H as second GPS was to connect a USB charger (unpowered) to the GPS USB port for a moment and remove it. It seems that it needs tohave a power consumption peak."
I'm curious as I have read this elsewhere...that is, one needs the 6 wire cable on the PH for GPS. However, the vast majority of "clone" GPS/Compass have a 4 wire to the PH and 2 for the I2C. So, I guess RTS and CTS are…"
"Hello Interested in Quads ,
I am very interested in the project you are describing. I am working on an engineering senior capstone project, and we plan on doing obstacle avoidance with the odriod xu3 and that same camera, I would love to hear…"
"I will second the Odroid. I have used it for this exact purpose.
Basically, I had anpu Odroid communicating with the APM (Pixhawk still works) and getting data from a USB Cam (Logitech C920). The Odroid ran Ubuntu with ROS. OpenCV was used to…"
HC-SR04 signal is not fed directly to Pixhawk/APM - the signal activation, calculations, processing and conversion is done with Arduino Micro. The output is just voltage from 0 to 3V - analog. I modified the code so that it will not go above…"
I actually don't know what was the reason I got it working. I did update (to the current version) firmware and after that it worked. You can try to reload the firmware, it should not hurt.
What you can check additionally is how you have…"
I dont understand the reason for this question: "Why are you using RNGFND_PIN = 13 and 14, RNGFND_TYPE = 1 (analog) on the Pixhawk?"
Are the instructions about pin mapping and MP comments wrong?
Because you have stated that the 3,3V ADC input 1 and input 2 needs to be mapped to pin 14 and 13 aka Sonar Pin 14 (Left sonar), Sonar Pin 13 (Right sonar). According to MP RNGFND_TYPE comment I need to use analog = 1.
HC_SR04 signal is…"
I need help with enabling The SONAR.
Description of problem and setup:
Pixhawk: RNGFND_PIN = 13 and 14, RNGFND_TYPE = 1 (analog)
APM 2.5: RNGFND_PIN = 0 and 1, RNGFND_TYPE = 1 (analog)
Under CLI I have tested SONARTEST…"
"I don't know if the algorithms you're going to use can be accelerated using the GPU (via OpenCL), but here are a couple of boards which came out recently which allow for a great deal of parallelism (great for certain types of machine…"
