Any microcontroller must have I/O pins for taking inputs and providing outputs. The ATXMega32A4U just like any other micro has 34 programmable I/O pins divided unevenly amongst six IO ports. Most I/O ports are 8 bit wide. XMega I/Os have digital, analog and special purpose functions. Some I/O pins have more than one use. A quick view of the XMega I/O pins reveals the purpose of these pins.

STM32 micros just like any other micro provide hardware for serial communication. As we all know serial communication is a very important tool for debugging, connecting with external hardware like RFID, GPS, GSM modems, etc. and for performing other communication-related tasks. STM32s have several hardware serial (USART) ports. The number of ports available in a STM32 micro is dependent on device family type and the device itself. Typically there are at least 5 serial ports. Apart from the basic serial communication needs, STM32’s USART hardware also have support for LIN, one-wire, smart card protocols, SPI and IrDA. We can even

MikroElektronika, a Belgrade, Serbia-based company is well-known for producing quality software and hardware development tools for a wide range of microcontroller families, including PIC, AVR, and ARM processors. Their mikroC Pro for PIC has always been my favorite PIC compiler, and has been extensively used in my PIC tutorials and projects published on this website, for its ease of use and rich set of built-in library routines. Today, I am reviewing MikroElektronika’s EasyPIC v7, which is the latest PIC development board in their line of EasyPIC series. I would like to thank to Newark USA for providing the EasyPIC v7 board

In this blog post, I am reviewing iCircuit Technologies’ iCP12 usbStick development board and their freely downloadable SmartDAQ PC software. These two can be bundled together to construct a very basic 6-channel (analog) PC data logger. The iCP12 usbStick is a PIC18F2550 based USB development board that comes preloaded with Microchip’s USB HID bootloader that allows users to upload an application firmware directly through a PC’s USB port without any external programmer. It provides access to its I/O pins through 0.1″ pitch headers. A slide switch is also provided on board to select the operation of the board in Bootloader or

A logic analyzer is an excellent tool for capturing many digital signals at once and displaying their timing relationships. It is particularly useful in verifying and debugging digital circuits. This tutorial is intended to provide a quick overview of a logic analyzer tool and its uses in analyzing and decoding data flowing on multiple signal lines or bus in a digital system. The logic analyzer tool is extremely helpful in troubleshooting problems arising from timing violations and transients on buses. In this article, I am going to use the SCANALOGIC-2 educational kit from IKALOGIC to illustrate very basic features of
