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

Official Page with More Information:

This is the fifth in a video series aimed to give a tutorial on the popular Atmel AVR Atmega32 microcontroller. In this video I test the programmer to determine the proper installation of the drivers, avrdude and WinAVR. The first circuit is also explained and built.

3AM and your videos are fantastic. I mean perfect. I've been trying to find a series like this for ages. And it's not just the programming, but you are answring questions that I tried to google with no avail, such as "When do I use resistors" etc... as I had forgotten all of my electric learning from school. Legend! I don't suppose I can ask for help with the programming should I run into problems? Cheers again!

@expurgatetor Thanks. It's my aim to document all of this for all of you, but also for me, because I forget, and I need to upload these back into my brain.

If you need help, I encourage you to post comments on the issues and I, or another avid viewer, can try to answer the question. This way, the Q and A can be seen for others as well.

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.

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, 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?

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