Atmel 532

Ok so I know this going to sound really dumb but what is an Atmel 532 chip good for?? I tried to google it but none of the results told what it is and what I could do with it? Can anyone here shed some light on it for me?

How to program ATMEL AT89S52 chip?

Hello. I'm new in forum. I buy a DIY Kit Secohmmeter Capacitance Meter Inductance Meter Frequency Meter, but the chip have no code. The vendor send me a link to download the schematic and the code in C and inn hexadecimal. But I don't know how to code the chip, the board have UAB_ASP connection. If anyone already use that kit and know how to code that, can explain how to code the chip? I attach foto and the code.  Thank's Miguel Rodrigues

Atmel AVR IDE/assembler won't run (Windows 8)

I'm trying to write some code for my AVR in assembly, but I cannot get either the Atmel studio 6.0 (with or without sp1) or AVR32 studio 2.6 to run. Studio 6.0 with the service pack states that it will work on windows 8 but consistently gives the error message "The application was unable to start correctly (0xc000007b)". AVR32 generates a Java error. This is consistent across all compatability settings and running as administrator. This is on a pretty much clean install of windows 8 pro x64, with all updates and the latest release of both 32 and 64 bit Java. All other software has installed and run without issues, including the equivalent software for microchips microcontrollers. I would appreciate any suggestions as to how to get this software to run, or any alternatives that may work. Thanks in advance for any help.

3 wire interface (GND, VCC, DATA)? Answered

Hi guys,   I'm trying to reverse the communications on a project I have at the moment which seems to be using a 3 wire serial interface (GND, VCC, DATA).  My goal would be to replicate the communications with an arduino or similar, however i'm not 100% sure what serial protocol it's using.   The device is using an Atmel ATMEGA168 and the pcb is covered in conformal coating, so I haven't had a whole lot of luck tracing the pins. I'm not overly aware of many one-wire communications protocols.  The datasheet says the ATMEGA supports various peripheral features, including SPI, USART, 2-wire serial (Philips I2C) (among others), however the GND, VCC, DATA configuration doesn't seem to fit with any of the supported protocols (i.e. there's no clock line and only a single data line).   The captures i'm getting seem to indicate that it's an 8-bit binary protocol.  I was going to try to decode it manually and attempt to reproduce it, however would be grateful if someone recognizes it and can point me in the right direction. Does anyone know any protocols / configurations this could be?  Example screenshot attached. Any help would be greatly appreciated!  Thanks!

Plans for AVR LCD display, need some help..

I've just ordered at ATMEGA644 after running out of space on my ATTINY2313 too easy. Along with that, i got a 20X4 LCD screen, character one that displays letters, and the cursors are 5X7 matrix.How does one write to a LCD screen? like is there a good place for a tutorial? maybe a simple sample code of HELLO WORLD? I know in DOS you need stlib or w/e, and you do printf("HELLO WORLD\n"); does it work similar to displaying on a 20X4 character screen? I'm a ok C programmer, knowing the basics to create little games with 3X3 leds and speakers. I've got a C programming book to help along with it. So feel free to explain, or just give code samples. i can figure it.

MCP2210 Questions?

"Don't believe everything you read on the internet" - Abraham Lincoln Such wise words I should have heeded.  Anyhow I have my MCP2210 wired up correctly now, the computer recognizes it, configured using the MCP2210 Utility and the GPIO pins have been tested and work through the SPI Terminal that I downloaded for another product related to this from Microchip. The question I have now is how much farther can I take this?  I started with this IC because I know (some) Arduinos use an FT232 USB to UART chip to connect USB to the Atmel chip they use.  I recall most Atmel MCUs can be programmed using SPI, so I figured I would try this out.  I also hoped this would delve into software so I could teach myself a bit about that as I am more familiar with hardware and building circuits.  If everything worked out I wanted to use these with an MCU so I could make myself custom small USB programmable boards for projects.  So would it be possible to program an ATTiny or ATMega through this using Atmel Studio 7.0?  What am I missing if it can be done?  What should I be researching next?  Anything to point me in the right direction is appreciated.  If this is not feasible, alright, what other applications would these chips as I have a few more of them?

(i already have a mechanical potentiometer at 30k ohm attached directly AC.. BUT..)   i know so far with the atmel i can f.ex. control a digital potentimeter 50k ohm, at 5v.. -> only DC no AC (+ i wont get a 1Ampere on 5V working) ------> my little MOTOR uses ~ 22mA on 230V = 5W    and what ive learned so far is that i might need one or two TRIAC or DAC combined with a POTENTIOMETER.. to control AC voltage and/ or an OPTO-ISOLATOR --never heared of that before..   but i have no idea how i should solder that together or will i need some extra RESITORS or CAPACITORS for it?   -> FINALLY i want to flash the ATMEL with a small arduino code and use a USB connection (+own software) pushing the potenial (resistance in the curciut) from 0 to 50k ohm into AC !
