Thanks for the replies. I changed my resistor for pin 3 and add 10 k to pin4. When I power it up, the second row (using a 16x2 lcd) is filled with 16 squares. Any idea why not writing some letters but filled squares?
My problem is LCD does not show up anything. The program was written in C and it is just to write 'welcome' on LCD.
@ckshivaram
Can you be more specific? I do not follow you.
Thank you again.
Thank you all for quick replies. I have checked my crystal using a LED blinking circuit and it worked perfectly. I tried the circuit using two LCDs so I do not think it is a LCD or xtal issue.
Hey guys. I am implementing a very basic microcontroller (PIC 16f887) circuit that basically sends data to LCD. I simulated the program successfully but when I implement it, there is nothing showing on LCD. I have checked the connections and two outta four of the LCD's data bits are on. The...
Martin Bates demo files
Hi guys i am studying pic microcontrollers from the book PROGRAMMING 8-BIT PIC MICROCONTROLLERS in C by Martin Bates but the demo files in the book's web site **broken link removed** are gone. Can anyone upload the demo files? Thank you all.
hi in the following months i can take assembly programming but it is for 80x86 series i think although it is not used when programming microcontrollers (as it is for pcs) it may be useful learning assembly programming.is it good for me to take (as far as i know assembly programming is different...
hi i am taking both logic and circuit analysis but i wonder what is inside an AND gate (also all other gates), transmission gates ,tri-state buffer and also dependent voltage or current sources can you explain or suggest some reading but note i havent taken any electronics yet thanks in adance
openham signals
this year i will take these courses and wanna know which book is best thanks for every single entry
1)circuit analysis
2)electromagnetics
3)digital systems
4)systems and signals
