  1. I wrote some code for the nokia lcd using spi a couple of months ago and after seeing Robs post I thought I'd post mine as well. sorry about the video quality I lost my good camera in a drift boat accident here's the code: /* * 4/5/11 * talk to nokia 5011 LCD with spi */ #include #define PIN_SCLK BIT5 //display pin 7 / msp430 pin 7 //port p1.5 #define PIN_DNMOSI BIT6 //display pin 6 / msp430 pin 14 //port p1.6 these are used for USI SPI mode #define PIN_DC BIT4 //display pin 5 / msp430 pin 12 //port P2.4 #define PIN_RESET BIT3 //display pin 4 / msp430 pin 11 //port p2.3 #define
  2. great job! nice work using the op amps. Ive done a couple of projects with the lm386 and been impressed with the results dont give up on it.
  3. For the bigger boards I used a Enshu DT center, its a gantry style mill where the X,Y, and Z are on the gantry and the table is fixed. For the smaller board I used a Fadal VMC15 which has the X and Y on the table and the Z is fixed in the X and Y. What do you mean tramming? from your video your setup looks pretty cool. me too what kind of driver boards ect.. are you planning on using? Ive been looking into it. Of course I would like to build the system myself , but dont want to re-invent the wheel.
  4. Hey Rob did you see this: http://www.buildlounge.com/2011/10/07/b ... er-cutter/ I think your project qualifies
  5. The small one took about 1 minute. The larger 2 took 15 minutes or so each to drill and machine. I usually run the spindle at about 9500 rpm and I run the engraving tool at 15IPM (inch's per minute).
  6. Nice work I would like to build a PCB CNC for at home prototyping but until then I use a machine at work. Here's a couple of boards I made By timotet at 2011-10-16 By timotet at 2011-10-16
  7. wow! lots of good stuff here on the STmicro board. I ordered mine on the 7th and got it on the 11th, never got a shipping confirmation. I would love to use open source software with this thing, but talk about overwhelming! If a noob to micro controllers and C programming can put in his 2 cents here's mine : I used to search the interwebs looking at embedded electronics thinking how I made an error in my choice of professions, I mean how cool are these little gizmos that you can program to do stuff, I mean all kinds of stuff. So finally after I got over being intimidated
  8. Wow Thats tiny Really cool display. Killer SMD work. I like it. good job
  9. Ok thanks for the code! RobG I tried yours first and the display is not correct. It is not displaying the numbers its displaying symbols. I think the + 30 is the culprit. opossum I tried yours second and its working correctly. the difference is in the + '0'. I understand that the +30 adds to the hex value that the character is supposed to be right? for the LCD so since the nibble has the proper value do we not need to add the +30. sorry if this is a noob question.
  10. WOW! you guys are quick thanks!
  11. Hey RobG Could you give a small example of how to use the Binary to ASCII code for the noobs like me? :shifty: I am working on a project that uses the TI RTC code. located here: http://focus.ti.com/general/docs/litabs ... r=slaa290a The output for the clock is in BCD and I have not been able to figure out how to convert it. I tried just adding 0x30 to the BCD output but that only works up to 9, so I though this may be the answer. this is from the TI info: "To be easily displayable on an LCD, all variables are encoded in BCD. All variables, except the year, use one byte
  12. I am messing around with this : http://focus.ti.com/general/docs/litabs ... r=slaa290a
  13. This looks great. nice work!
  14. Great project! It would of been nice to have this 30 years ago so I could have proved to my brother my car was faster than his!
  15. looking good Rob. cool enclosure.
  16. I had the same new software apprehensions, but so-far pleasantly surprised. multiple sheets and a 1 meter square board size! also the 3d model pretty darn cool! When I first tried eagle I said to myself Ill never make a board larger than 3" x 4" , but I was wrong.
  17. I just downloaded and am trying DesignSpark. so far its pretty cool too. http://www.designspark.com/
  18. Dont you need to use PWM to play multiple tones? Can you use the watchdog to create PWM? I didnt see that in the user guide. @dannyboy Did you use a certain program for getting the notes to the song you used? thanks tim
  19. hey look at this viewtopic.php?f=10&t=509 and to let you know you dont even need to use the watchdog for this. the delay is the problem use this delay instead : static void delay(int ms)// Delays by the specified Milliseconds { while (ms--) __delay_cycles(1000); //set to 1000 for 1 Mhz } and take out the watch dog interrupt call all together. and be sure to put this in WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer TACTL is for TIMER A and has nothing to do with the watchdog. page 410 of the msp430 users guide will explain the TACTL register and wha
  20. bluehash Thanks for your time with this. I changed the int notes to const int notes and that was it. It also works with or without the _disable_interrupts() command. It has to have the __no_operation() command. return does not work . It works with or without #include . Isnt this for interrupts in mspgcc? I was thinking about this yesterday after we had been working on it and had the thought that changing int notes to const int notes might do the trick. All though I did not know what exactly that did. So its nice to know for the future. thanks again
