Also If there is a schematic of the BME688 board available? Would have made things much simpler to understand.
Hi kgoveas,
I also met some difficulties on BME688 Development board Communication protocol recently. And it's quite helpful to see this reply.
But I am still struggling with the issue after I got the details. Here are my codes. Would you mind giving me more hints please?
Thank you!
#include "Wire.h"
#define SDA 23
#define SCL 22
void setup(void)
{
Serial.begin(115200);
Wire.begin(SDA, SCL);
foodSensor.begin(BME68X_I2C_ADDR_HIGH, Wire);
Hello all ,
I would like to know if anyone was able to communicate with the Bosch BME688 kit sucessfully with custom built firmware ? I would like to know which pins of I2C expanders are used as CS select for interfacing each sensor with the controller.
Hi electro_bloom,
Have you already seen the samples from Github?
There is a mini library called CommMux Bosch-BSEC2-Library/commMux.cpp at master · BoschSensortec/Bosch-BSEC2-Library (github.com) that abstracts the use of the IO expander to control the 8 sensors.
The use of the library can be seen here : Bosch-BSEC2-Library/basic.ino at master · BoschSensortec/Bosch-BSEC2-Library (github.com)
Hope that helps,
Regards,
kgoveas
