Tool/software:
Dear E2E Team,
I would like to generate a sequence of chirps with incrementally increasing start frequencies for each antenna (Tx1, Tx2, and Tx3). To achieve this, I modified the chirp settings in the mmwaveconfig.txt file for each antenna as shown below:
#Chirp Configuration parameters, please modify if needed.
#rlChirpCfg_t
#
chirpStartIdx=0;
chirpEndIdx=15;
profileIdCPCFG=0;
startFreqVar=1988100;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=1;
#END
#
#Chirp Configuration parameters, please modify if needed.
#rlChirpCfg_t
#
chirpStartIdx=16;
chirpEndIdx=31;
profileIdCPCFG=0;
startFreqVar=1988100;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=2;
#END
#
#Chirp Configuration parameters, please modify if needed.
#rlChirpCfg_t
#
chirpStartIdx=32;
chirpEndIdx=47;
profileIdCPCFG=0;
startFreqVar=1988100;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=4;
#END
#
#Frame configuration parameters, please modify if needed.
#rlFrameCfg_t
#
chirpStartIdxFCF=0;
chirpEndIdxFCF=47;
frameCount=1;
loopCount=100;
periodicity=100000000;
triggerDelay=0;
numAdcSamples=1024;
triggerSelect=1;
#END
Based on the configuration above, I expect that initially 16 chirps will be generated with start frequencies of 76 + {0, 0.106, 2×0.106, ..., 15×0.106} GHz, transmitted by Tx1. Subsequently, the same sequence of chirps will be transmitted by Tx2 and Tx3 in order. This entire process is intended to repeat 100 times.
However, I would like to confirm whether the above configuration is sufficient to achieve the desired chirp sequence, or if additional settings are needed (e.g., enabling advanced chirp features or dynamic chirp configuration). Furthermore, I would appreciate any guidance on how we can validate that the start frequency changes are being correctly applied.
Thank you in advance for your help and advice.
Best regards,
Ramin
