  1. Hi Guys, I have solved the problem. I started from scratch with a new plugable breadboard and launchpad board and everything works. I have no idea what caused the problem but thats life... Anyway, thanks for the help. Steve
  2. Thanks Guys, That's given me some points to look at. First thing is to look at the start up times. As the Arduino works fine with the display and the MSP430 does not I am wondering if there is some difference between the Arduino and Energia versions of LiquidCrystal.h Steve
  3. er....forgot to mention that the backlight works, with this display you don't see anything without the backlight...
  4. Hi Guys, Sorry to bother you but I have hit a fundamental problem which I cannot get any further with unless someone else takes a look. I have an MSP430 Launchpad EXP430G2 board with the '553 processor installed in the DIL socket. No clock crystal installed. I have a working RT162-7 display, data sheet here := http://www.ladyada.net/media/lcd/RT162.pdf powered by a separate 5 volt supply. The contrast pot meter works and I can adjust the contrast. I can see the little oblong boxes where the characters display. I know this works because I pulled it from my Arduino system,
  5. Thanks for all the hard work guys.... Downloading it as I write Steve
  6. Does anyone happen to know if they will drop the old MSP430 board with the DIL socket? I hope not because it is nice to be able to use it to develop using the DIL packaged MSP430 parts then solder them into the target system.... Also I am developing a course specifically for the DIL board and it would be a real pain if it became unavailable.... Regards Steve
  7. any news on when the GCC port is available? Or is this the wrong place to ask?
  8. Hi guys, Very interesting dissection. If you need different or wider frequency coverage there are a couple of other options. At the lowest price range you can simply get a DVB/TV dongle like this one https://www.cosycave.co.uk/product.php?id_product=282 and choose from a number of public domain software packages. I have one of these http://sdr-kits.net/VNWA3_Description.html which is very good for antenna analysis. Hope this helps.. Steve
  9. Udv, I think my last reply used all the Magyar words I know! I am a frequent visitor to Budapest though. It is nice to see that at least one person in Hungary is having fun with micro controllers. Regards, Steve
  10. Jo napot Mybuster! Szep MSP430 design. Szia, Steve
  11. COBOL would pretty much do what you want Abe...... that, and FORTRAN are what real programmers used to program in before we went "back to the future" and adopted C. :-)
  12. I also would like to see the Si570 code. I have a big interest in this chip having worked with it since the early days. My friend jan G0BBL did the original design to multi band the soft rock SDR with it....I did a lot of beta testing for it. 73s Steve G0XAR
  13. Mon ami Jean-Yves, I am really sorry. I just found your reply. My course plan is to take a different approach. Each lesson has an example program which is useful for a ham. Then I discuss it in detail using the code to teach simple aspects. Then I get students to modify the code so they can learn. So far I finished one lesson on LED blinking. The second lesson uses the temperature sensor on the MSP430. The code monitors this and if it gets too high switches a LED on, and a fan, and sounds an alarm. We take the processor off the Launchpad board and build a little circuit with the proce
  14. Hi Graham, As they say in Australian "No worries!". Let's have a virtual beer together and forget about it. I was in a bad mood this morning and over reacted. Life is too short! I am enthusiastic enough about Energia to be writing a course using it and the 430 Launchpad for radio hams who are frightened of computers. So everything has to be broken down to "Janet and John" bite sized chunks. It's a challenge. Like you I find the need for "Arduino Compatibility" a drawback. But on the plus side it has opened up the MSP430 to a lot of people who wouldn't have given it a second glance. An
  15. Hi Guys, Just out of interest, is there anything else available in the public domain? Cheers, Steve
  16. Graham, I think you have missed the point here and quoted me out of context. The book is aimed at beginners to learn program using Energia, not "C". Had you taken a look at the book you might have realised this. My comments were made with beginners in mind. So when @LRS asked the question "So this is for energia? Not to learn msp430 programming in C assembly?" I told him as much in the simplest way possible, in a way that a beginner, whose first language is not English, might understand. And I gave the guy details of a book that will help him or her to learn these skills. I think that
  17. Thanks Pabigot. I found quite a few references after my post. All things considered an external RTC chip or a 1 pulse per second output from a GPS module is going to be my best solution. I want to keep the code simple enough for people without much programming experience to follow. As far as I am concerned this thread is closed. Cheers, Steve
  18. Hi Guys, This is as much hardware related as Energia related but stay with me. I I am going to write an application in Energia to switch a low powered (< 100 mW) radio transmitter on and off in morse code. Accurate and repeatable timing is critical. But once set up there is nothing else for the processor to do. I can choose between the default clock in the MSP430, the Clock xtal which came with the launchpad or, if I must, a Rb 10 MHz frequency standard to clock the MSP430. The latter solution is a pain in the bum, but I have one with a TTL output so I guess possible. I'll be looki
  19. May be Yan can help? He is an MSP430 expert and lives in Vietnam.
  20. I would like to suggest another improvement for the book. Which is to add a section on using the Launchpad as a "programmer" and having the processor on a target board. This is not so difficult to do and has been covered in the forums. I think it would be a good idea to have this at the end of the book. So readers thinking about a project don't get into the mindset that they always have to have a Launchpad and a booster pack to implement their ideas. One of the nice things about the Launchpad is the inbuilt "programmer" and debug facilities. I also do some AVR programming, to get similar f
  21. @LRA ..... The book is for beginners. No "C", no Assembler! Try this one, it has both :- MSP430 Microcontroller Basics by John H. Davis ISBN 978-0-7506-8276-3 This is a good but a little dated book on how the processor chip works. Chapter 7 about interfacing is very good for those of you with some electronics background. The book is not for beginners but if you have done some "C" programming and worked with other microcontrollers you will benefit from it. Hope this helps ! Steve
  22. Hi Guys, I have the book. I am not that impressed with it. I think for a raw beginner who can get hold of the Educational Booster Pack it's probably not too bad. But the Booster Pack seems only to be available in the USA. So to order it from Europe I have to pay for shipping, 20 percent VAT and a customs inspection fee. This turns out to be a very expensive option! OK, so there are instructions to use a breadboard. This is good but you still have to buy the sensors and the same applies. If you can't find a local stockist you have to order these from the USA... :-( . I would have preferred
  23. Merci bien Rei Vio, I just transferred the work to my Win 7 Laptop for a while. Now all I need to do is to get Serial.print("hello"); to output hello to the monitor program rather than garbage and I'll be back on track ;-) Regards, Steve
  24. It's not the board that's bricked as it works fine on my Windoze 7 laptop :-)
