MCS-51 / 8051 – Hello STC89C52
Sources are available here. After going over the background of the 8051 architecture in part 1 of this series, let us have a look at a simple “Hello World” example for this microcontroller. For this post, you either need an STC89C52 demo board, or you can breadboard a minimal STC89C52-circuit as follows. For the bootstrap […]
MCS-51 / 8051 Revived – Introduction
This is the first post in a series of posts to shed some light on the 8051 architecture using practical examples. The 8051 was first developed by Intel in 1980. It was initially used as a keyboard controller for the IBM PC series. The simplicity and low-interrupt latency made it an attractive part that was […]
