The I2C devices:0-002a,0-0038,0-0039,0-004a,2-0028,2-033. These entries have the formB-SSSSwhereBis the bus number andSSSSis the I2C address of the device. So you can see that for example0-004acorresponds to the cs42l51 audio codec we mentioned earlier. In our case, we are i...
The X-CUBE-CELLULAR expansion package is a software solution that embeds a cellular middleware package, a set of projects, and an application example, featuring an STM32L4 microcontroller acting as a host for cellular connectivity applications. Combined with Truphone ST Authorized Partner, this exp...
