Hi Kris,

How to install properly the Adafruit library for the Ladybug?

TY Cédric

kriswiner commented 7 years ago

Hi Cedric,

There is no Adafruit library for the Ladybug. Not sure what you mean here.

Euh,

I think we need sone *.h for this file : https://github.com/kriswiner/Ladybug/blob/master/MPU9250_MS5637_BasicAHRS2_Ladybug.ino

kriswiner commented 7 years ago

Either comment out the display calls or go over to Adafruit and get the library. I am not sure what you want me to do here.

Dear Kris,

Do you know if it's possible to increase serial bus speed upper to 115kbps?

kriswiner commented 7 years ago

You mean serial bus speeds higher than 115200 on Ladybug?

clemaitre58 commented 7 years ago

Yes

kriswiner commented 7 years ago

Yup.

(short German answer).

In detail,

230400 460800 921600

There is 2 hairs in the soup though. One is that higher speeds only work if there is DMA attached to a serial port internally. Usually we do that only on RX1/TX1.

The 2nd hair is that you may need to increase the RX buffer size (See Uart.h ::begin(baudrate, config, buffer, size)), or you might want to use the onReceive() callback to drain the RX buffer early.

Other question.

for code : MPU9250_BME280_BasicAHRS2_Butterfly Do you use DMP ? For which use?

kriswiner commented 7 years ago

No, I recommend against using the DMP.

Here is the raw output of A (without Madgwick) in mg : 0.14, 1.41, 25.83

same values with just return the package 1.31, 0.38, -27.17

why there are no g in the values?

NB : no modification of your code, just change the print

kriswiner commented 7 years ago

No idea.

Are you sure the MPU9250 is on the I2C bus? Can you read the WHO_AM_I value? Are you using the interrupt?

I have no idea what you are doing...

Oops it's my fault… It's a normalisation problem…
