A new version of the RobotC Driver Suite has been released.  Two new drivers were added and some improvements were made in the I2C bus error handling. Changelog: NEW: Added driver for AT24C512 EEPROM chip. NEW: Added Light Sensor driver with calibration!  You can use one of the test programs to calibrate for both white and black.  Calibration data is ...

The HiTechnic IR Link is capable of many things including controlling your Power Function devices.  The one thing you couldn’t do was transmit regular data.  That is, until now.  The IR Link has several transmission modes, 0x02 for example is used for the PF functionality.  There is another mode 0x00, UART-mode, which can be used to transmit 8 bytes at ...

A new release of the drivers has been uploaded.  No code changes but the minimum requirement has gone from RobotC 1.40 to 1.46 after problems were reported with some of the drivers. RobotC 1.46 can be downloaded from the following location: [LINK].  There is also a 1.47B available, which can be downloaded here: [LINK]. The drivers’ Source Forge project page ...

A new release of the 3rd Party Driver Suite for RobotC is out! This version is RC1. The obligatory Changelog: – Driver for the new HiTechnic IR Seeker v2 (HTDIR) has been added – Driver for the HiTechnic Compass Sensor, which I had forgotten to include with beta1 has been added – New experimental function in the NXTCam driver to ...

Several months ago I saw on the Mindsensors website that they were looking for beta testers for their upcoming Line Leader sensor.  I applied and shortly thereafter I was contacted by one of the guys there named Deepak. He told me they were still in Alpha testing phase but that they’d get back to me when they were ready to ...

After many weeks of writing and testing, I’m ready to release my first suite of RobotC drivers for quite a number of devices and sensors.  I’ve tried to make sure that every API call was documented and (almost) all drivers have an example program to demonstrate how to use the driver.  The documentation was created using Doxygen. The drivers make ...

What is nicer than attaching a Sharp IR sensor to your NXT?  Attaching 8 of them, of course. That is what my friend Helmut wanted to do with his NXT.  Unfortunately, as good a programmer as he might be, messing around with electronics just wasn’t his “Tasse Tee” (that is cup of tea for you non-German speaking folks). 8 Sharp ...

Technorati Tags: NXTCam,Mindsensors,NXT,RobotC I got a Mindsensors NXTCam2 for my birthday last year but hadn’t had much time to play with it yet.  That is, until today.  The NXTCam2 detects objects by matching them to one of 8 user-programmable colour ranges.  The objects and their colour can then be retrieved via a few trivial I2C commands. You would think that ...

I’ve been quite busy the last few days with various performance testing.  A friend of mine is keen to develop a robo-football platform.  Due to the nature of the game, very fast sensor updates and processing is required to track the ball and the opponents.  I’ve offered to work on an extension for the NXT allowing him to hook up ...

Here’s the first release of the HiTechnic Prototype Board driver for RobotC.  It has all the basic functionality you’ll need to use it. byte HTPBReadIO(tSensors _link, byte _mask) Returns values of inputs specified by mask void HTPBWriteIO(tSensors _link, byte _mask) Writes values to outputs specified by mask void HTPBSetupIO(tSensors _link, byte _mask) Configure the ports for input or output according ...
