I would like to ask if pixhawk and APM2.5 have the same "motor to channel map" as the code in ap_motors_class.cpp is written as below:#if CONFIG_HAL_BOARD == HAL_BOARD_APM1 const uint8_t…Continue

"Hi Shyam, Thank you for sharing. I would like know how it's done. I am planning to send the message directly from one pixhawk to another pixhawk using telemetry. I have been studying the code for weeks but there are still things that I…"

"Hi Jake, I would like to know if i need to configure the APM to send the data. As from what I observe, the code given below is for the receiving end. Does that mean that the APM sends the data by default and we just have to receive and decode it?As…"

"Does anyone know how to get the motor start turning in the V3.2? it seems to me that  hal.rcout -> write(pgm_read_byte(channel),pwm) would work, but somehow it didn't.  Can someone tell me why?"

"@Chris, I do not believe that either the PX4 or the Pixhawk navigation processors are in the modified Arduino IDE HAL  dropdown board selector. At least the last time I looked they were not there. Regards, TCIII ArduRover2 Developer"

Hi,I am new to Pixhawk. I just bought a pixhawk and want to upload my arducopter code (I added my own flight mode) to pixhawk using arduino. However, I found out that the selection of hal board in the arduino does not have pixhawk as one of the option. Does anyone know how to upload arducopter code to pixhawk?See More

Problem with the AP_InertialNav

I am using APM 2.5 with GPS and I am trying to get data such as position and velocity from AP_InertialNav using get_position() and get_velocity(). However, I noticed that the position and velocity provided by these 2 functions are not very accurate. The values keep fluctuating and never converge even my APM module was not moving. Does anyone come across this problem? Any solutions?See More
