"I've been using my pixracer successfully with ppm for some time. Today I tried to use my Spektrum transmitter (Dx6) with Lemon DSMX receiver.
My radio calibration screen just shows 0s for all channels. I've verified with a scope that the data is…"

"Did this ever get resolved for you? I have a pixracer and a dx6 that I can't read from"
"I am having an issue on the pixracer board. I am using the PX4_PWM rangefinder. It works fine, and CH5 on the board reads the correct distance. However, enabling this rangefinder kills the output on CH6. I'm no longer able to use it as a servo.…"
"I have the pixracer working with code compiled from the master. On my pixhawk I can use the px4flow module, but on the pixracer it fails to open the driver. I can't find the source of the problem in the code. Does anyone know the issue?"

"Looks like my issue was that the compass was not enabled. It shouldn't need to be for optical flow, but it's all ok now."
"I realized my rangefinder value was erratic at takeoff. I moved the rangefinder higher, and it now has better performance, but still no Opitcal Flow control. Log is attached.

"I just tried adding the PX4 optical flow module onto my copter. I also have a maxbotix 1040.
I have set:
EK2_GPS_TYPE = 3
FLOW_ENABLE = 1
EKF_ALT_SOURCE = 1
I have had good success following the test document listed here:…"

"Another question:
I have the px4Flow sensor working on a PixHawk on the I2C port, but the same sensor does not work on the PixRacer I2C port. Is there a code reason for this?"

"Marcell,
Thanks for your response. I do see that in the boot log file (rc.APM), but I was wondering how it was handled in the actual initialization functions. I'll keep looking into it."

"I see that the pixracer uses an ICM20608 IMU. AP_InertialSensor_PX4.cpp only handles initializing MPU6000, MPU9250, and LG3D20.
How is the inertial sensor properly initialized on this board?"

Does anybody know why there is a ~100ms delay between receiving a RC command and when the motors begin to respond?I put a logic analyzer on my RC channel 2, which is pitch, and on the PWM outputs of each of the 4 motors. just to be clear, this is…
"I forgot to mention that Acro trainer is set to 0."
I was wondering if someone could help me. I have a copter that is leveling out in acro. The logs are attached.The P gain grows like it should as the angle error grows, but my copter does not respond. I am using v3.3Thanks2016-05-02 18-06-44…
I am developing my own flight controller board using the STM32f103RE, the same CPU that the flymaple board uses.However, I am using an MPU6000 on SPI so I am using the AP_InertialSensor_MPU6000.cpp file. Monitoring the output using UART, everything…
"Did you try flying? Was it the same?"
