hi group has anyone an idea of whether it is possible to speed-control a 3-phase brushless motor with MSP430F14x from my point of view it should be possible because of the many compare registers of TimerA and TimerB - application note? - motor drivers? - code examples thanx for any help Manfred

Check out the Ti application reports handbook (SLAA024) SECT 4.11, PAGE
4-115 ONWARDS. iNCLUDES HIGH VOLTAGE 3 PHASE BRUSHLESS dc MOTOR
CIRCUITS. These examples are based upon the C3xx cries processors, but
are equally valid for any modern part with sufficient timers (Timer A5
or B5 for example.
Thids manual is an invaluable aid to any MSP430 developer, no matter how
experienced you might be. Contrary to the title it covers lots of things
that are regularly queried here, such as register usage, instruction
decode, recursion, reentrancy, floating point, square root routines,
integer maths, DCO stability.
Every MSP430 developer should own at least 1 copy, even if it is old
like mine (2000)

There was a time when I'd go outside in winter and have snowball fights
with the kids, wearing jeans and a T-Shirt, but now I'm older and even
perhaps a little wiser.

I think Adelaide's about the size of Portland, Oregon where I'm near. I'm a little more than 10 degrees closer to my pole than you are. Even Hobart is too close to the equator for my tastes (what with a 75-year record low of -2C, Hobart is a little hot for my liking.) Dunedin in NZ is closer, perhaps. Only half the rain, though. 16C is the temperature I like for sleeping naked on the floor -- just slightly overwarm, so no need for blankets or sheets at that temp. Anything over 5C is clearly just T-shirt weather. I confess to wearing a thin, light windbreaker at 0C. I like a week or two in the -10C region each year, if possible, and enough snow and ice to stand on it without cracking through. Haven't used my coat in years. 25C is painfully hot and by then I'm thinking about packing my bags and moving a quarter radian closer to the nearer pole. I'm Swedish and my skin is essentially transparent, my hair a light golden color that lets the sun burn my scalp, too -- I paid for every freckle with 2nd degree burns (raised welts I often get in less than 15 minutes of sun at 35 degree latitudes where you are at.) Not interested in more of the same. This area of Oregon is perfect, 25km from Mt. Hood (which rises about 3.5km above surrounding ground level.) Near constant cloud cover all year, with a few days of open sun a year, and 170 cm of rain a year, spread out roughly evenly, every day. Only a few days in winter below -10C and only a few days in summer above 25C. 120 cm of fantastic soil anywhere you look, everything grows so well that moss and lichens will grow from your car's trim and rubber seals! Also, you just toss some seed without bothering to plant and it grows, if it doesn't rot from fungus first. ;) Here's some trails on my property: http://users.easystreet.com/jkirwan/Home%20Trails.jpg http://users.easystreet.com/jkirwan/Home%20Trails%202.jpg ...and with the sun peeking through the fog: http://users.easystreet.com/jkirwan/Day%20in%20the%20Woods.jpg WGS84: N 4526'25.8" W12223'43.8" N 45.4405 W122.3955 Jon

The rest of Australia considers Adelaide to be a farming village of approximately 1.2m people. (ie sydney siders and melbournites consider South Australians to be a bit rural, but having lived in both of these cities I prefer rural to feral. ;@} > I'm a > little more than 10 degrees closer to my pole than you are.

I used to enjoy the cold, and still do, it's just that my definition of cold has shifted. When I lived in England I slept with the windows wide open in winter, and just a thin quilt. In my army days I used to do winter survival training in Norway, literally living in the snow. I don't sleep on floors, I had enough roughing it in the Army to last a life time, now I consider the Holiday inn to be as close to sleeping rough as I'd like to get;. My old bones appreciate a mattress. > 25C is painfully hot and by then I'm thinking about packing my bags and moving a > quarter radian closer to the nearer pole.

Not interested in more of the same. My middle brother gets very sick at temperatures much over 20-25C, while my elder brother is just the opposite. I feel the cold, but am not really uncomfortable from it, like wise the heat. I spent years working the middle east, including the sahara regions. The hottest I experienced was at j'aloh Oasis in Libya, at 58.5C. too hot to sweat. I went swimming, then for a jog (I was a lot younger then!) The coldest probably around -30C. Earlier this year Adelaide exprienced it's hottest period on record, several days at 47C. > > This area of Oregon is perfect, 25km from Mt.
