http://www.microcontroller.com/news/Atmel_ATtiny_4_5_9.asp These Atmel ATtiny microcontrollers have 6 pins, and an A/D. Draws a measly 100nA in sleep mode. Article shows a useful pinout (what's the pinout on a 6-pin microcontroller?), a block diagram, and an interesting competitor analysis. Pretty funky little device! - Bill Giovino Executive Editor http://Microcontroller.c...

Hi, I want to port an exisitng C++ code from windows into a microcontroller to carry out real-time processing. I guess the problems are the processing speed and size of code. I guess I can resolve the code size by using external memory to store the code but processing speed might be an issue. What other factors would I have to consider when selecting a microcontroller for my project? I wou...

I am tring to interface PS/2 mouse (optical) with a 8052 (AT89S52) microcontroller. From what I get from the internet without adding any extra hardware I cannot interface the mouse directly with the UART (serial port) of the microcontroller (mouse has data and clock lines; uC has RXD, TXD). 1. Are baud rates defined for asynchronous serial communication? What are the common baud rates used ...

Hi guys, Is there any way by which I can interface a mobile phone to a microcontroller or PC ? I am working on a hobby project where my objective is to ask the mobile to send an SMS to a particular number. I have a PC/microcontroller that would some how direct the mobile phone to send some specific message to a specific number. Alos, if some message is recieved on the mobile...

Hi, I have a microcontroller with GPIO, I2C and UART, and I'm trying to emulate a 1-wire interface so that the microcontroller appears as an i- button to another ASIC. I'm wondering if it would be easier to use either of the serial channels(UART or I2C) or should I just emulate it with GPIO? Would also appreciate any tips/help on how to emulate, and 1-wire standards, since I'm new to 1-...

With so many different types of microcontrollers and manufacturers on the market, it is rather difficult to know where to begin. What I need is something that has the following features: * very small in size * very low power consumption * at least 64 k of storage purely for storing data (this is in addition to my program's space) * some sort of interface to connect the microcontroller t...

Hi We are developing a USB device which is based on AT91SAM7S64 which has a 64K of flash in it. We want to store some specific data like Serial No of the device etc. into the flash of the microcontroller permanently. But the issue is we can not write the data into the program code of the microcontroller as constants, because this data is going to be specific for every single device and we do ...

Hi, I am doing a project using 8051 and GSM module,SIM900B. I am using a 8051 microcontroller to send AT commands to GSM module and store the data in an array and send the stored data as a text message to a mobile . I am able to see both gsm module and microcontroller unit working perfectly when connected to computer seperately through serial cable,but when I am connecting both the devices with t...

Hi, Queestion as topic : does anyone here know of a microcontroller that can operate with supply and I/O between 4 and 7 volts ? If I could have anything I wanted then a SiLabs 8051F320 would be perfect but they can only go to 5.25V. Alternatively almost anything in the TI MSP430 series would do at a pinch but they also only seem to support supply voltages up to 5.5V max. Of course I...

I am doing a project where I need an interface between mobile phone and microcontroller. Actually I need to process text message on microcontroller. The mobile phone has USB output, and I found that PIC18F4550 has USB input, but both of the device acts as slave not as host. I also found that some mobile phones like Nokia 6610, Nokia 6610i and, Nokia 6210 have serial port which I can interface wit...

Hi - I ran into PSOCs a little while ago - and I'm having trouble figuring out *what* exactly they are... Cypress calls it a "mixed signal array" - which is a term that I'm not very familiar with. They say it has a microcontroller, along with a number of configurable "elements" (that can be set to be ADCs, DAC, timers, PWM, etc.) But my understanding of a microcontroller is that it essen...
