Discussion in ‘ General Electronics Chat ‘ started by iccoolApr 8, Apr 8, 1. Apr 3, 5 0. I had only little bit of knowledge of electronics. I had done some very small projects from circuits in books. I searched and found some ICs that can be used, please advice me which one can be used, if anyone can give a circuit that would he very helpful. Apr 8, 2.

Jul 17, 22, 1, Take a look at using a CD with a CD One is a 3-digit BCD counter, the other is a 7-segment display counter. You can cascade the 3-digit counter to create a 6-digit counter. The PIC16F87x series is obsolete. The replacement series is PIC16F88x.
They are much less expensive, and have their own internal clock so that a crystal oscillator is not absolutely necessary for operation. Programming a PIC has a rather steep learning curve.
Once you can master the basics of it, you will be able to do a lot of things that would require a great many discrete logic ICs. Apr 8, 3. Aug 30, 1, If you c4d553 to look at what’s involved in programming you can go to: Apr 9, 4. First of all thanks to. Apr 9, 5.
However, you will also need to learn some of the peculiarities of PIC Assembly language, and how to set the various options for the uC itself.
There are a practically bewildering array of PIC uC’s out there nowdays. If you are going to want to use the MikroC demo program for the 4 digit counter, you should look in the source code first to determine which PIC they used.
I’d downloaded MikroBasic awhile back. There is a demo MikroBasic program like Gerty mentioned for a 4-digit 7-segment display. At that that time, the demo program required: The requirements may have changed; you will need to look in the demos for the software suite that you download.
There may be a similar demo program in MikroC; I don’t know as I have not downloaded it. Apr 9, 6. Mar 24, 21, 2, Just a basis of information Apr 9, 7. Feb 14, The common Anode or common Cathode ones? Apr 10, 8. Thanks for the quick reply SgtWookie Sorry, I downloaded and installed mikroC, but cannot find 4-digit 7-segment display cv4553 example folder.
For PIC16F88x, the ‘x’ is still in search. Here is the link of PIC16F Because of that I datazheet that IC in cf4553 first preference when I started. Only problem is can I choose it for large display 4″. Here are the details of those LEDs datasheet is attached in my first post: Forward Voltage – Typical 10mA: Apr 10, 9.
It’s the current, not datazheet size, of the LEDs. I’ve thought about making my own 7 segment displays using discrete LEDs where the digits were over 1′ high. The drivers would be virtually identical.
Apr 18, It is really a struggle to get the components here in our small town. I got some components from nearby town. Still to get the desired 4″ 7 Segment Display. The info datashest the datasheet is wrong! I was able to purchase these products and my first part almost went success. I was happy to see the circuit almost working well hxxp: I will get new LEDs to test in coming week.
In that way I datasheer see through the starting of programming. Any links I can check for that. Unfortunately I cannot find much info when I searched.

I was in the same boat back then. Radio Shack is not a great parts source. I would use the phrase “barely adequate”. A teen generally has to depend on their parents for checks I didor credit cards to pay datsaheet mail order. As I got older I got a checking account to pay for my parts.
Where to get cd45533 is a legitimate subject for this site. This is why most of the experienced folks put their location as part datzsheet their profile to be displayed on the corner of a post. If you are in need of parts, ask for some good sources. BTW, here are some plans I drew many moons ago for a set of stadium lights, They have never c4553 built, but maybe some day. Multiplexing has several functions, a big one is to reduce the number of wires carrying the information for a display.
For example, the first attachment got 4 digits down to 8 wires, I was thinking of using Cat5 wire. I will try to reduce the number of wires, but my problem is in the function of keypad.
It has 16 keys and 8 output pins. Testing continuity of pins after pressing a key do not give any result. SgtWookie You are right, it may be because of the current limiting resistor.
I missed thatbecause I started with very low voltage I do not put resistor. That may caused the problem. So not able to calculate correct value of resistor I saw one of your post about the resistor value calculation. I know it is too much for a student. It is a little after the smoke has escaped, but have you read this?
