CCSTUDIO: [BUG] syscfg generates invalid .modulation.deviation

Nuno Gonçalves

Part Number: CCSTUDIO
Other Parts Discussed in Thread: SYSCONFIG, CC1352P7

Tool/software:

Code Composer Studio 20.2.0
sysconfig_1.21.1

With syscfg GUI create RF Stack - > custom -> Proprietary (770-930) -> Deviation (kHz): 1000.0

Generated file ti_radio_config has .modulation.deviation = 0xFA0.

.deviation is a 11 bits bitfield which does not support the 0xFA0 value.

Bug might be related to not using the deviationStepSz field.

Hi Nuno,

I don't think we support this kind of deviation, even if you use the step size field. What kind of data rate is your PHY?

Did you see this app note on creating new PHYs?

1000 kHz was just an example to show how syscfg GUI doesn't provide any warning and overflows the variable in the generated code, which happens above 512 kHz if step stize is not used.
