STM32F103C8T6 with BMP280

[Abhishek1352000]

I want to use BMP280 with STM32 for controlling my drone

Welcome,

did you try what ag123 suggest:

Can you give me any link or help me out with a code for altitude hold feature for a drone using bmp280
I am working with STM32F103C8T6 , mpu6050 and bmp280

The forum attempts to help you solve your coding problem or STM32 microcontroller configuration issue. We do not generally handle pointing Ops to specific links on acquiring such things as flight controller software. A drone forum or Google is likely a more successful approach.

Was unable to find any related post for that hoping you guys know this stuff as i am new to all this

Here is a link to a video regarding the 180 sensor. If it is similar to the 280 then it could be useful.

Years ago, I made a Barometer with a BMP180:

It may not be exactly what you are looking for, but you may find it interesting.

Difference between BMP180 and BMP280
The following table shows the difference between the older BMP180 and the replacement part BMP280. Note how the BMP280 has far better specifications and has multiple interfaces including high speed SPI, whereas the BMP180 only has I2C (you could have ordered a separate part with SPI). The other major difference is that the BMP280 has a selectable filter operation with 5 different bandwidths resulting in measurements with higher accuracy.

Comparison of BMP280 and BMP180

Note: Temperature accuracy data is (buried in the data sheet):

±0.5°C (at 25°C) and
±1.0°C (over the full temperature range 0°C ~ 65°C).
