Microchip and Seven Segment displ.

Hello Everyones,

I have now arradised more questionss about Microchip!

So this goes for those who worked with it or with the 4511b seven segment display controller.

I want to be able to display numbers from 2.2 to 12 with 2 seven segment displays. For this task I am planning to use two 4511b to reduce pin count. Now since I am a noob in this C language I would like some help for starting.

PIC12f675

Hello,

I would like to know if the PIC12F675 from microchip can control 2 LDRs, a buzzer, and a LED. I know it might sound a simple question but this is for my starting project with Microchip and C programming.

If it is possible I would appreciate if someone could tell me how to wire the components to the PIC.

Thanks, GranTotem

:D

PzKw "Tammy"

Start me notI decided to do this Tamiya tankbot as a blog as there's been a few similar posts lately and It is probably one of the most common platforms about the net so I will see if I can do something different with it. But for starters I have built it like a start here robot although I will not call it that.
At the moment it is controlled by a pic16F690 but I intend to build different configurations using other micros as well.

PIC Is TTL or CMOS?

Hi all, I have question about PIC16F877A... I need to interface it with other ICs like 7segment drivers,
and I have to choose between TTL and CMOS technology. But I can't find out on the datasheet if the mcu is in ttl or cmos one.
The final question is: have I to consider the 16f877a a ttl or a cmos IC?
Many THX in advance ;-)

Microcontroller Recomendations

Hey all,

Which microcontrollers to you recomend? Which are best for beginers ( and the bank:-)? Thanks for the help.

Homebrew Servo Controller Issues

Hi,

I've been developing my own serial servo controller for the hexapod I'm working on, using a Microchip PIC16F74.  It accepts serial input and controls up to 20 servos. The servos are connected in ports A, B and D.  Power for the PIC is from a 9v battery via a 7805 regulator.  The servos have a separate power supply from a 6v battery pack.

Ultrasonic range finder SRF04

Hi,

I am a beginner. 

I have got a PIC18F252 to run a line follower robot. I would like the chip to run an sfr04 ultrasonic range finder SRF04.  basically if the SRF04 detects an object infront of it, it then turns away.  I am programming in C and am stuck. 

Has anyone got a programme or could somone please point me in the right direction.

 Any help would be great

 Thanks

What microcontroller shud i use?

hi i plan to make a hybrid-quad-walker with wheels on it's feet.  i have figured out that it need to dirve 12-14 servos depending on if it need a neck and head etc. and it also need to drive 4 motors or 2 motors! and then it need to drive a ultrasonic sensor and a few simple inputs! it's best if it is programmed with a USB port  

so please help me find a (not too expensive) microcontroller...

Other compilers to Microchip PIC's (get more out of your picaxe)

It seems quite expansive, but as I understand it, these compilers

http://www.hvwtech.com/products.asp?CatID=90&SubCatID=127&SubSubCatID=0

Both C, and a pre-compiled basic (no-Picaxe bootstrapped needs, use raw chip)

Aparently this way you can take your picaxe-projects, and take them to the next level if you need faster execution, wants to code in C, need floating point etc..

- But not cheap!
