Microcontrollers - AVR Atmega32 - Testing the programmer and building the first circuit

[DYLAN102001]

Hello, I'm building a z80 computer with graphics and I want a tms9918 VDP to generate the NTSC signal. The tms9918 requires a lot of software "bureaucracy" if you what I mean to, lets say, put a ASCII character on the screen of draw a sprite in the video memory so I want a microcontroller to act as a "ambassador" between the computer and the VDP.. would a microcontroller like the one your using in this video be able to do this and is it possible to synchronize the computers clock with it?

[glenn22dv]

Can you use flowcode to pogram the avr with that programmer?

[glenn22dv]

don't you need a crystal to generate the clock pulses?

[anajonesr]

@glenn22dv No, there is an internal clock in the microcontroller. A crystal is needed for more precise applications, like time of day, synchronizing serial communications, etc.

Wait a sec, if i typed Microcontrollers that means i know what a resistor and LED is right?

[m7ammad7assan]

i follow all your procedures correctly but when i tried to use avrdude as the movie the result that i got is a message told me" avrdude : Error :could not fined USBtiny device (0x1781/0xc9f)"

can u help me on solving this problem pleaaaaaaase

[anajonesr]

@m7ammad7assan This sounds like a problem of the windows locating the programmer. your programmer may not be functioning, of the driver is not installed correctly.

hello.

What is the model of the programmer? Can I also program other atmega models with it?

I only only usb port at my PC, what's why i am interesed by this model.

[anajonesr]

@Shukaru100 I have the information and links at the newbiehack site under "MCU programmer 1"

[steinstolper]

when i plug in the programmer into the microprosessor the blue light of the programmer turns off and there is a error when i use avrdude -c usbtiny -p m32

[addy3x]

thank you !!!!

can i also programm the chip and plug it to a battery (no computer) ?

[anajonesr]

@addy3x Good comment. Yes... you can use a battery or another power source, but you will want to have the battery or voltage source be regulated. This is a really good subject for a quick video.

[guitardenver1]

When i type avrdude -c usbtiny -p m32 it gives me an error saying installation failed, rc=-1 double check connection and try again. Help would be great!!!! it recognizes the usbtiny. just not the chip a guess. I am using the same chip. mega32

@guitardenver1 same here

this is so cool! is there a playlist?

[addy3x]

@f0ckt

yes, search for Microcontrollers - A Beginner's Guide

[KingNetherdrake]

Hey nice videos, can you turn this into a playlist so it's easier to watch them all consecutively? Thanks :D

[anajonesr]

@KingNetherdrake I think I already have a playlist, but if not, I will surely do so.

[h2oreactor]

thanks for posting again... it's been years since I program ATMEL uC, but I'm enjoying your tutorials, I need a refresher course anyways.

[anajonesr]

@h2oreactor Yes, this is exactly why I'm doing it. I go back and forth from project to project and the process becomes a bit hazy when I get back into it. Making these videos and content on the website is sort of a note-taking endeavor while I get back into embedded programming, but this new project will last for many years, so there is a lot to show. I also love making videos. It helps me think.
