Let’s now look at using PASM and C in the same stretch of code using a technique called inline assembly. You can use this when you require the fastest possible execution of a small section of repeated code. The main part of the code remains in C, but the critical section is written in PASM. In Figure 16-1, there is a drawing of the Antarctic Snow Cruiser: a hybrid exploration vehicle that was ahead of its times.
In this example, we will read the input pin MISO 32 times and shift the value into a ...
