![]() ![]() If you modify the I2C address of the PX4Flow, make sure to start the PX4 driver with the correct address: px4flow start # address=0x42 (default) There are different I2C readouts available.ĭetails about the I2C frame and the I2C integral frame are in the driver source code. The address range for the 8 possible choices is: 0x42 - 0x49. If all jumpers are unsoldered, the camera will be automatically discovered by the autopilot firmware. The address increment is equal to the 3-bit value encoded by the jumpers.įor example if jumper 0 and 1 are soldered and jumper 2 is unsoldered, the address is incremented by 1*1 + 1*2 + 0*4 = 3, which gives address 0x45. This is useful if another device has the same address. ![]() The default I2C address of the PX4Flow is 0x42, but it can be incremented using the three solder jumpers labeled "I2C BUS ADDR". If you are connecting multiple devices to the same bus you will need to set each with a unique address. (see Hardware/issues/8 for more information). PX4Flow emits a significant amount of electromagnetic radiation, and should be placed as far away from other electronics (in particular GPS modules) as possible. Make sure the the PX4Flow board is well dampened. The above orientation maps to SENS_FLOW_ROT=270 degrees (the default). On PX4, the orientation should be set using the parameter SENS_FLOW_ROT. The recommended mounting orientation (meaning: zero rotation) is defined as Y on flow board pointing towards front of vehicle, as shown in the following picture. Update the firmware on PX4Flow using QGroundControl (in the top left menu, click on CONFIG, then on Firmware Upgrade)įlow data should be coming through at 10Hz if the autopilot is connected via USB.įlow data is transmitted via wireless at a lower rate.This does not work on FMUv5 (Pixhawk 4) for PX4 versions less than 1.9.0.Īll other PX4/Firmware versions should work. In order to use the PX4Flow board, just connect it with I2C (on any Pixhawk series controller).
