Programming the FLiP module over WiFi

Introduction The Parallax WiFi module adds wireless programming functionality to Parallax Propeller MicrocontrollersThis tip concerns the Propeller FLiP module, and how to connect the FLiP and WiFi modules together. Connections There are 5 connections including power and ground: Parallax Propeller…

asmclk and the automatic clock setter

Introduction For customers writing PASM2 only programs, the compiler automatically prepends a clock-setter function to the code so that the system clock settings are automatically calculated and configured without the need for user configuration. It just works! If you don’t…

Handy Diagnostic Heartbeat

Introduction Each of the multicore Propeller 1’s eight processors (cogs) has two independent hardware counter modules. Each counter is a configurable state machine for sensing or generating repetitive signals, potentially on every clock cycle. The counter modules are flexible subsystems…

Customer Code Deployment in one click

Introduction Propeller Programming Script – For the Parallax Propeller 1 Microcontroller This batch script provides a way to achieve one-click updates for customers, using a standard Windows batch script for compatibility with the widest range of Windows versions. This avoids…

Sharing variables between SPIN2 and PASM2

Introduction Code for the Propeller 2 (whether written in the native SPIN2, C or other high level language), can usually benefit from a bit of PASM2 (assembly code) to help create super-fast drivers for real world interfacing! That PASM2 code…

Keep any value in range

Introduction The Propeller native SPIN and SPIN2 languages include many efficient instructions to solve common programming tasks. For example, how to keep a value between a certain range of allowed values? Here’s an example using just one line of code!…

Determine pin state - High, Low or Floating?

Introduction A common requirement for programmers is to determine the external state of an IO pin. The Propeller 2 smart IO pins make this simple without needing any external components, and allow the programmer to determine if the pin is…
