Hi, I went through the Sampler_8bit code. As you mentioned, it’s really a good starting point to understand the API’s. In the code, the ‘playbackBuf’ is initialized with value 128. Is it just a value to write to DAC during the first ISR or 128 has any significance?
I think from the second ISR onwards, the ADC read value (signal) during the previous ISR and stored in ‘playbackBuf’, is fed to the DAC. Is my understanding correct?
