Increase PX4 Flash Log Rate

Started Jun 4 0 Replies

I am trying to increase the sampling rate of the DataFlash logs being saved to the MicroSD card on Pixhawk. (Primarily raw IMU data). I'm using a Pixhawk 2 board with Mission Planner and…Continue

Increase PX4 Flash Log Rate

I am trying to increase the sampling rate of the DataFlash logs being saved to the MicroSD card on Pixhawk. (Primarily raw IMU data). I'm using a Pixhawk 2 board with Mission Planner and QGroundControl.I can't figure out how to use "sdlog2" considering the terminal no longer works to my knowledge. I've also messed around with the LOG_BITMASK parameter but nothing actually increases the sample rate.From what I heard here…See More

Pixhawk Mini RC Passthrough

Hi,I have a Pixhawk Mini powering a hexacopter and I need to pass through a couple auxiliary channels. Six of the main output PWM channels are going to the ESC's, but I want to get two more PWM channels on 7 and 8. I have AUX1 and AUX2 set to Channels 7 and 8 (respectively) in the pixhawk parameters. Am I missing something with this setup?  Using an oscilloscope on channels 7 and 8 on the PWM breakout just gives a steady signal that doesn't change with RC input..Any thoughts would be much…See More

"I'm also trying to figure this out. Can GPS data only be tagged in radiometric TIFF or can I use radiometric JPEG?"

"I actually haven't seen that board but I may look into it. I probably will be sticking with the Mini for this project though. Have you flown with an X2.1?"

"I may try this, I just wasn't sure if it had to have the RX signal too. The FLIR documentation says it uses RX for Heartbeat but I don't know if that is mandatory."

"Buy a Mrobotics  X2.1 autopilot , it has 3 telemetry ports and IMO is much reliable than the Pixhawk Mini."

"If the Flir only needs to read the stream, you can just split the TX signal from the pixhawk to the radio.."

Pixhawk Mini Telemetry with FLIR

Hi,I am currently working on a hexacopter powered with the Pixhawk Mini FCS. It is currently using the 915MHz telemetry radio to communicate with my ground station. I am mounting a thermal camera (FLIR Vue Pro R) which has a port to accept Mavlink for tagging geospatial data in the thermal images. Unfortunately the Mini only has a single telemetry port. Is there any way I can run telemetry to/from the radio AND to the FLIR at the same time?I understand that telemetry is a serial connection so…See More
