hi
i am using PIC30F5011,
I want to display like 12 on SSDs,i have two SSD's with commaon anode and both common's are connected to Two NPN tranistor .some one suggested me use multiplexing,i am using PORTB0 to PORTB7 for SSD's..SSD pins are connected both SSD's are same.D5 and D1 are...
Hi,
In the circuit we have displays in HH.MM.SS format and all first displays are connected in parallel and second displays are connected in parallel, Is it possible to display 12.34.56 according to this circuit.
Thanking You,
Varma
ok jayanath,
I have done the same with a simpler code. I have done ligthing up individually and now each segment is working.
But then I tried to high all seven segment at once i have errors in getting high all at once and when I gave a little delay in between and given high to all seven...
Jayanth , thanks for prompt reply! But Im not able use you HEX file !
But my intention was to display my adc values which look like 230.66. So in the case I have been trying with 5 seven segment displays.
I was clear with reading my adc values with the processor I am using where I place the...
hi thank you jayanth.
i am using only that circuit but i want display numbers like 12345(DIS1=some integer,DIS2=some integer,DIS3=some integer,DIS4=some integer,DIS5=some integer) and i taken only 5 7-segment display . actually my target is displying ADC value(voltage). i am using 8MHZ crystal...
hi
can you plese send link or information about MUX.

hi jayanth
i want display like 12345 but as per circuit how can i controlled DIS1,DIS2,DIS3,DIS4,DIS5. i attached circuit diagram above .in the place of AT89C52 i am using pic30f5011.
hi nick703
i am using pic30f5011 micro controller.actually this circuit i taken from electronics for you pulse book.in this circuit they are using AT89C52 uC but i am using pic30f5011
hi
I am using five 7 segment led display common anode(DIS1,DIS2,DIS3,DIS4, DIS5) in my project.i want to control each 7 segment display differently .but in my circuit connection are alternatively connected same pins are e,d,c,dp,b,a,f,g(DIS1,DIS3,DIS5 are same & DIS2,DIS4 are same).
but my...
hii.
You aren't declaring a type for the extern variables, the compiler probably assumes they are 16 bit However, if they are actually bytes then they can be at an odd address which then fails in your function.
Hi,
I have been using dspic30f5011 , and while initilizing the processor in the project wizard, I have found two options i.e, dspic30f5011 and dspic30f5011e
I cross checked across Google and couldn't find any documentation.
Any help to enlighten me about the difference of usage.i am using MPLAB...
HI jayanth,
I have initilized a buffer array , char buf[24];
wrote an ISR as you mentioned
configured bits as
U1STAbits.UTXISEL = 1; // Interrupt when a character is transferred to the Transmit Shift register
U1STAbits.UTXBRK = 0; // Operate U1Tx Normally on Transmit Break Bit...
