Now that we are all up to speed on Spin, let’s plunge into PASM. Here I introduce the form and structure of PASM cogs and the details of PASM instructions.

In addition, I spend some time talking about how to pass information from the main cog (generally the driver program in Spin) to the PASM cogs. In this chapter and the next one, we will need to pass all the same variables (nsamps, sampsBuf, etc.) to the PASM cog as we did in the Spin version.

Remember, the cogs are almost completely independent of each other. To communicate ...
