December 2024 monthly summary for lnls-sirius/dev-packages. Focused on stabilizing ADC sampling configuration handling. No new user-facing features delivered this month; major improvement came from a bug fix ensuring accurate sampling frequency retrieval for ADC configurations by returning the computed fadc directly when the acquisition rate begins with 'adc'. This fix aligns the sampling frequency with the configured ADC rate and improves data acquisition reliability.
