Freescale Programming?

Out of the many samples I recieved last week, the freescale MC908JL8MPE is one of the few that I like the look of. Its a beefy PDIP with 28 pins, unlike the many TQFNs I've recieved I could actually solder this (well no need as it fits in a breadboard). But my problem is, there doesn't seem to be many easy-to-follow tutorials for programming these microcontrollers. The only simple solution seems to be to buy £100 programmers.. which I'm not too keen on. Is there a simple way to program them via parallel/serial or maybe using my usbtiny to program an atmel chip to program the freescale chip? Thanks.

Another source of info and ideas

Although this forum gets very technical at times, it can still be a great source of ideas and specs. Here is the link to the FTF (Freescale Tech Forum).With a very long video located here: Video Link for those that wish to listen to a lecture :-)

accelerometer based mouse, what happens when tilted

I got a free dual axis low g accelerometer from freescale, the output voltage is proportional to the g forces, I also have a ton of free PICmicro chips with I2C and A/D converters. I want to make a mouse just basically for proof of concept. I was thinking about how to program it, since I want to tell the computer the "movement since last request", I would need to calculate the speed using the g force reading (9.8m/s2 = 1g)if the mouse is moving at a constant speed, the g force would be 0, and the speed would be the same as the last reading, also, gravity affects the reading if the mouse is tilted slightly, increasing the speed even if it is not moving at all, so I was thinking, if the mouse was tilted, and then balanced again, the speed would remain the same, causing annoyance to the user. this is the problem i would like to solve.Is there a space efficient way to make a accelerometer not affected by tilt? if not, is there any tricks I can use (such as detecting unusually uniform g force and automatically go into "joystick mode")? I have been thinking about using a thumb button to zero the speed (while held down, the mouse can also do "super precise mode" which means one pixel per half second no mater how fast), is the thumb button the way to go? how about sensor to see if there is contact with a surface? or four IR rangers to detect tilt while above a surface?side note: does anybody have a datasheet for ata1060xa? its a optical mouse sensor with built in 27mhz RF transmitter made by @lab, and they don't share datasheets.oh and head on over to cypress for free wireless usb modules (2.4ghz i think, multiple channels) if you are interested in cheap RF, i have two with 50 meter rangeinfo on mouses and keyboard serial interface found herehttp://www.computer-engineering.org/ps2protocol/

Brains for a robot?

It's time I turn yet again to the forums for advice, this time on recommended robot brains! [Serious] I have a project for a class requiring design, construction and programming of something. More than half of my fellow students are doing clocks of some sort, be they binary or nixie tube. A friend of mine is doing a holonomic robot, and my plan was to do a walking robot, based on ideas like the WowWee robosaurus, using a simple tail and head to balance and few motors to run it in comparison to any conventional biped. As far as servos, I was hoping to use something like the HerculeX or other serially connected servo, so I can just daisy chain the few I would need and simplify the wiring, as well as get experience with serially addressing things. Planned sensors are 2-4 IR rangefinders, 2-4 wire whiskers and one tilt switch to turn it off if it tips over. Sensors I'd love to add would be something like a super basic camera for simple machine vision if I ever learn to code that well, but I doubt that will be the case; and the LIDAR thing from the Neato XV-11 which is again unlikely. Things I was looking at for super basic use included: Arduino, HC11 MC (backplane type), BASIC Stamp, PIC. For a little more complexity I was seriously considering things like the Freescale Tower ARM, Gumstix or other. I'd love to have the serial servos, sensor assemblies and the camera and have integration with Robot operating system through an onboard computer, but I have no idea what to use to setup ROS or what would be best, or if my plan of parts to use is even good enough. In other words, what ideas should I throw out as impossible or what would I need for say, ROS use? Ideally i want to do a semi autonomous robot, so that i don't have to manually direct it everywhere, but I'd still be keeping an eye on it when it's running so it doesn't break something. If I understand ROS correctly I can use an external computer to control it, but I can also let it be autonomous? Coding math and logic in the machine language for a Z80 computer doesn't really prepare for robot building, although the class is basically a teach programming basics and throw you into the deep end. [/serious] Thank you in advance for your help!

DIY DVR (PVR ?)

No, not the mythTV variety, but the real deal. I've been messing with uCLinux on various chip, which led to a vague daydream that I sketched out on the train today. These are my notes on a personal DVR. I say personal because its design for MY needs, and not the typical user. It also happens that no commercial DVR will meet these specs without being mired in lawsuits (see replayTV). Why an embedded solution and not MythTV? I've had mythtv boxes, they can be a lot of fun, and a lot of frustration. Mostly, I don't have room for a second computer, I don't want to use a ton of energy to record a few programs, and no matter where it ends up in my apartment, I will be able to hear it at night. MyDVR: I already watch all my TV on the computer. Either by TV tuner or Xvid. I don't need a Tivo style DVR that will play back content on a TV with a nice menu display. I need a mass storage device that records TV shows. I want Xvid. MPEG2 is huge. Its also kinda ugly. I really really like the look of the XVID codec. It takes a reasonable amount of space for a decent encode (~178 meg per ~20 minutes HDTV). I want multiple tuners...I mean, what if there are two (or five) programs to record simultaneously? Basic design: A motherboard with 32 bit CPU running uClinux (probably a chip from Freescale). These usually have USB and an ethernet MAC (but no PHY). USB 2.0 mass storage device emulation on the USB port. This way the unit can be hooked up to a PC for easy video extraction. This might also have some configuration abilities, but that would require a custom mass storage controller driver - YUCK! Ethernet with HTTP server for show scheduling. IDE interface to a big hard drive. The tuners and encoders would be on add-in cards. The add-in cards would have: 1. A tv tuner. 2. A DSP with xvid encoding. 3. Probably a small uC to control the DSP and tuner. Whats already in my knowledge domain (stuff that I already know about -or- could I really do it?): 1. I've been messing with uClinux for a while. What fun. 2. USB mass storage controller implementations are numerous. check. 3. Embedded HTTP server - check. But I have not routed a PCB using an external PHY. This looks messy. Perhaps a ENC28J60 instead? 4. I've been reading up on some XVID DSP implementations. There are also some commercial MP4 chips, but I bet they're pricey! 5. I picked up a bare PAL tuner at the surplus shop. Time to play. There are a few things that make this project easier than a Tivo clone. There is no video output. No need to do fancy display overlays synced to the incoming/decoding video stream. This is encode only - no need to load, decode, and display the XVID. I'm kinda testing the waters on this project. I'm going to get some DSPs and try to do real-time XVID compression. Also, I need to figure out the tuner card. Any suggestions within the scope of this project would be awesome! Especially if you've worked with uClinux and have a processor recommendation.
