I am actually try to use Laser ranger finder to estimate the distance to the fire source, by the word "neutralise". i actually referring absorption laser frequency, when that happen the laser will always see a spread of spectrum not really it transmitted beam. i believe most laser range finders...
I am currently having challenge on how to use laser range finder to measure distance to fire source. my worries is, the fire source may neutralise the laser spectrum thereby making the receiver see no reflection.
is there anyway this can be done?
Please i need your help.
Thanks alot.
i can give you detail about the display in attachment. however the board is product of EVTECH i could read 2CH00929A at the back of the display,
the features are: 74HCT595 are arranged 4x4 column and rows, all pin 13 are grounded, all pin 12 are connected together, all pin 11 are...
thank man for your reply

help me develop assembly code that will received ascii charater from PC and save them temperaly in internal RAM then write messages on 5x7 leds, scrolling left to right, right to left up and down.
the components intending to used are 74LS138, and AT89S52. with PNP transistors.
i have been having problem using Assembly language to program my AT89Sxx series of uC.
would any one assist me with keil C compiler and the tutorials?
deavong@yahoo.com
i will be glad
Would any one help explain each step of this initialization?

Assemly code Please
The second circuit i have is 5x7 Matrix, take a look at the connection and see how you may help. my target now is to get used to writting on LED displays. Thank if can provide me with the assembly codes, containing the ascii table and different effect of scrolling.
i need help
i Will be glad if any one will help me with the Assembly code for this schematic, different effect like srcolling left to right, right to left, up -down down -up e.t.c
also how can i write on 5x7 or 8x8 led matrix
I need help.
i need to write closed in a LED 5x7 matrix when P3.7 is high and Closed when P3.7 is low. my connection is Unl2003 form my row driver common cathode. 745HC95 form my column drivers. four in number, 6 xter.
the hardware is ready but the Assembly code im having difficulty espectialy...
