    i love to learn about low level programming :)
  1. ok, best of luck then its really enjoyable project
  2. ok, wat ICs are you going to use in them?
  3. no, i didnt make it from an existing schematic, its a new concept, i didnt write any code for it, as i had to show it to my college, so it has to be formal, i will write some formal code, to demostrate the cube, but it can be coded easily like every other cube...
  4. This is an 8x8x8 LED cube, designed by me, i think its the most compact circuit i have ever seen on the internet regarding a cube of this size...
  5. new project - LED propeller, its pixels are fixed, the speed of the motar have no effect on that.... http://www.youtube.com/watch?v=4jmODg4TcKE
  6. well, i named it gameboy, because i didnt design it for only the pingpong, it can have many more games in it, so i thought it would be better to call it a gameboy... but actually, i think i have never used a gameboy myself, so i dont know the exact concept of it... [oops]
  7. can anyone tell me, how to enlarge the images i uploaded here? :\
  8. hi friends, this is my project on Digital clock, using MSP430G2452 [u can use any 20 pin MSP controller], i have uploaded its schematic with the code here, you can see it working at... clock.pdf clock.sch main.c
  9. no i havent, thats very good idea thanks, i m searching for its contents
  10. thanks to all of you friends... username the pair consists of an IR led and a PHOTODIODE, because ir can penetrate through human body more easily [i think] and the pulse generated by the heart affects the reception, which is then amplified and filtered by 2 op amp amplification stages, and then given to the msp430.... simpleavr it was necessary to give 5 volts, as the LCD works on 5 volts, and decreasing the voltage in the sensor section means decreasing the voltage for the IR, which effects the sensitivity... i have given nearly 4 volts to msp, [using 3 diodes in series] bluehashwhat is HR?
  11. This is a heart beat counter, which displays the result on an LCD, it amplifies the signal by a dual op amp IC, and passes it to msp, as an interupt to count the number of pulse for 15 secs, it uses internal clock, so its not so accurate, but it will give you a good precised result... i have given all the neccassary information, including the schematic, the video link, and the code, with the header file.. here is its video... see the instructions to build it at http://www.instructables.com/id/Heart-Beat-Counter-using-MSP430/ lcd.h main.c
  12. thanks it is quite good but i dont know its working, maybe i will see it on youtube thanks
  13. Veryalive yes, i havent shown the PERFCT diagram, but as you can see in the INSTRUCTABLES i have shown these connection very clear in one image, showing the ACTUAL connections on the board.... here also i have uploaded it... see it... http://forum.43oh.com/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=3934 the connections i have shown here are the ONLY connections which are must connected exactly, to run the code neatly on your board... - shift reg clock connected to latch clock - both driven by 430 (pin?) shift clock is not connected to latch, they both are different, shift clock comes from msp430g2553's spi sclk pin, i.e P1.5, and the latch clock is p1.4 - Reset tied high and Enable tied low yes, reset is active low, or we can say that it resets on falling edge... - Serial data into one 595, driven by 430 (pin?) p1.7 - D7 out from one shift register cascaded to Din of the next one. yeah - Did you use CCS for this? ofcourse i have written this in the begining of the code /* * pin configuration - * p1.0 - switch1 * p1.1 - switch2 * p1.2 - switch3 * p1.3 - switch4 * p1.4 - latch clock * p1.5 - shift clock * p2.0 - switch5 * p2.1 - switch6 * p2.2 - switch7 * * p1.7 - data output */ i have made a little changes in the schematic diagram for you, now see if you can understand the connections nicely.... i have named the wires, see it here, i have replaced the schematic diagram.... my advice is to see the instructable's page first and then act on it...to understand the schematic diagram nicely, you have to know the pins of 74595 and msp430gs2553, then you will get which clock pin or data pin is connected to wat... sorry i didnt have much time to draw a neat diagram so i just made a rough one, the data is shifted twice in the registers, so that it becomes a 16 bit data, 8 bit for the anodes and 8 for cathodes of the matrix... feel free to ask any questions, because when i started to make it, i knew no one who had made this kind of project by msp430... spirilis thanks man, i havent seen the working of TRS-80 model 100, and i dont know anything about it >.< but thanks, power was never a thing for me actually, my thing was using each button as an interrupt, i.e. using 7 buttons and a 8x8 screen with 16 pins of msp430, and in that also there were a few pins which werent used, and this system is pretty heavy to be made at home due to so many inputs and outputs.... thanks for your comment, i hope you can give me a few more ideas to work on...
