AWR1843: 1843

Hello Dim,

The start frequency of the chirp and slope is programmed by the profile config API. Are you using your own application to configure the AWR1843 or are you configuring it using mmwave studio?

hallo, i making own application. I cant finde adress and how to access register , whitch control carrier freq. and what hex value writte to get 79.0 GHz carrier?

Hello Dim,

In that case I assume you are using the mmwave SDK as the starting point of your application. In the mmwave SDK you can find the "rlSetProfileConfig" API that can be used to configure the frequency during the chirp.

Ok

In API I found :

/**
* @brief Start frequency for each profile \n
For 77GHz devices (76 GHz - 81 GHz): \n
1 LSB = 3.6e9 / 2^26 Hz = 53.644 Hz \n
Valid range: 0x5471C71B to 0x5A000000 \n
For 60GHz devices (57 GHz - 64 GHz): \n
1 LSB = 2.7e9 / 2^26 Hz = 40.233 Hz \n
Valid range: 0x5471C71C to 0x5ED097B4 \n

 rlUInt32_t startFreqConst;

By this calculation , to set 79.1 GHz 0x57e3a195

is it right?
