Hello everyone. I have a CruxF405HD ELRS AIO which has a BMP280 on board. I am having trouble configuring. From the BMP280 manual the default i2c address is 0x76.

I have this configured:

get baro

baro_bustype = I2C
Allowed values: NONE, I2C, SPI, SLAVE

baro_spi_device = 0
Allowed range: 0 - 5

baro_i2c_device = 2
Allowed range: 0 - 5

baro_i2c_address = 118
Allowed range: 0 - 119
Default value: 0

baro_hardware = BMP280
Allowed values: AUTO, NONE, BMP085, MS5611, BMP280, LPS, QMP6988, BMP388, DPS310, 2SMPB_02B, LPS22DF, VIRTUAL
Default value: AUTO

altitude_prefer_baro = 100
Allowed range: 0 - 100

There was a small note from the vendor instructing me to set device=2 and did not mention i2c_address which defaulted to zero, both zero and 118 have no change, I've also tried all device values 0-5 for the heck of it.

Barometer is enabled in configuration as well. Is there anything I might be missing here? Any advice or debugging steps would be greatly appreciated! Thank you.

Did you include the BMP280 define when flashing Betaflight?

#

Post the output of status in the CLI

analog quiver Apr 30, 2024, 4:21 PM

Last night I attempted to build 4.5.0 with cloud build with custom defines "BARO BARO_BMP280 GYRO_SPI_ICM42688P ACC_SPI_ICM42688P" but the build failed, I had assumed those BARO includes were already being included elsewhere. I can post the build logs. (I'll go attempt a build now).

#

Also, your arm switch is not set properly. Arm must be on Aux1 high for ELRS

analog quiver Apr 30, 2024, 4:30 PM

#

Will do! I have not taken flight with this unit yet, just spending a lot of time DD on betaflight in general. One question, before I make this change, would I expect the barometer not to work without battery power? This might be my issue?

spice fractal Apr 30, 2024, 4:30 PM

#

It is possible the baro is only powered by the battery, not USB

#

But you should make the change above regardless, and also fix your arm switch

analog quiver Apr 30, 2024, 4:32 PM

#

Regarding arm switch, i intentionally configured so that the switch would arm on AUX1 when it's away from me. It lights up and i haver my range configured properly in betaflight, are you saying this will not work the way I expected? I havre no probleming moving the range to the other switch position.

spice fractal Apr 30, 2024, 4:33 PM

#

If you want the switch to be armed in that position, invert it on the mixer page of your radio

analog quiver Apr 30, 2024, 4:34 PM

#

Understood.

I made the above suggested changes, saved, powered up battery, then plugged in usb cable. Baro = Not Detected

#

Yeah, this was where I was questioning if I had overlooked something 🙂

#

There's nothing from the very very sparse information from happymodel that this would be SPI.

#

I could contact them separately to confirm though

#

When I first used the resource I2C_SCL 2 B10
resource I2C_SDA 2 B11 instructions they barked (warned) that they were assigned to UART3. but didn't seem to be an issue as I don't think UART3 is used anywhere on this FC board.

Just to clarify, I dumped cli, flashed core only and the restored dump... I have a feeling this is not what you wanted.. I can repeat and just set the two resources as requested?

#

It also appears my ACC and GYRO are not working either. Was this just a debug step to help diagnose? I have to include the custom defines in order to get those sensors functioning.

Step by step 🙂

step 1: only flash core only - and apply my 3 lines - before showing status

Indeed uses ICM42688P - so this needs to be added [in a new HM config for this board]. But core only should include all drivers and nothing shows up. This is the confusing parts as we had a working gyro here: #1234901402606899283 message

Maybe add BARO_DPS310 GYRO_SPI_ICM42688P ACC_SPI_ICM42688P might work from there.

But it should work with CORE ONLY
