Poor Mans Scratch Sensor Board

“scratch-sherpa” implements the protocol of the Scratch Sensor Board (also known as Picoboard), as supported by the educational Scratch  programming environment. A MSP430 Launchpad with my uSherpa firmware as foundation is used. For more details, see the project page here Get the sources from github The (unedited) video below shows some examples of how the […]

Carambot First Autonomous Drive

This shows the carambot driving around autonomously by using the ultrasonic range finder together with the pan servo. The algorithm used is pretty simple (see Python snipped after break).

Carambot Update

This is work in progress, so see it fail :-). What you see in the video is an update about the robot I am currently working on. It uses a Carambola MIPS SoC which communicates to a MSP430G2553 on a TI Launchpad through serial line. The Launchpad runs a “special” firmware I am currently working […]

ROCKETuC Introduction

I just made two short videos introducing the main features of the ROCKETuC project I work on with Alexander Reben. The first one gives a basic introduction to ROCKETuC and what you can do with it, the second one shows how external interrupts could be used with ROCKETuC and Processing. Basically I made them to […]

Robot with MSP430 Launchpad as Brains

Longhorn engineer has has a nice and clean robot build with an MSP430 Lauchpad as Brains on his web-page. I like especially the design of the power supply: It has 3 switching power supplies providing 3V at 4A, 3.3V at 500mA, and 5V at 1A. The main power source is a single cell 3.7V lithium […]

HOWTO: MSP430G2xxx Stand Alone

I wrote up a little HOWTO which shows how to drive a MSP430G2xx MCU standalone (without Launchpad). It also shows, how to use a Launchpad for in circuit programming through only three lines (Spy By Wire). In the HOWTO, we first will have a look on the most minimal set-up needed, to run a MSP430 […]

HOWTO: MSP430G2553 Hardware UART

I made a small example showing how to use hardware UART through USCI_A on the TI Launchpad with a MSP430G2553 MCU. Receiving is done through interrupts. Got to the HOWTO page Get the code at github Note: If you have an MSP430 MCU which does not support hardware UART (e.g. the MSP430G2231), have a look […]

HOWTO: MSP430G2231 Software UART

Update: I made a second example based on the one TI has in it’s examples. It is based on Timer_A for RX and TX. You can find that example in the “timer-a-uart” branch. This example shows how to use software UART on the TI Launchpad with a MSP430G2231 MCU (which does NOT have a hardware […]
