Asynchronous Syscall Capsules
Alexandru Radovici, Ioana Culic · Apress eBooks · 2022
The previous chapter has covered all the details about Tock capsule types and how to develop a simple Syscall capsule. This chapter aims to extend the capsule from chapter 8 and allow it to write more than one character. While the previous capsule version received one character and displayed it, this version will receive a string of characters to display. The capsule will display a digit or letter, wait for a small amount of time, then display the next until it reaches the last character.
