LAN ports, 1 PCIe mini slot, 4 DIs, 4 DOs, 1 m. SATA slot, and 2 USB 2. Features and Benefits. Overview. The UC 8. A Series embedded computers support a rich collection of communication interfaces, including 8 RS 2. Ethernet ports, 1 PCIe mini slot for a wireless module, 4 digital input channels, 4 digital output channels, 1 m. SATA slot, and 2 USB 2. The UC 8. 41. 0A computer uses the Freescale Cortex A7 dual core 1 GHz RISC CPU. This powerful computing engine supports several useful communications functions, without generating too much heat. The built in 1 GB SD card and 5. MB DDR3 SDRAM give you enough memory to run your application software, and the m. SATA slot provides the flexibility of adding additional data storage. The UC 8. 41. 0A comes with a variety of communication interaces, including serial ports, Ethernet ports, wireless communication slot, and digital inputoutput channels, making them ideal as communication platforms for industrial applications that require network and device communications. The UC 8. 41. 0A Series comes with Linux Debian 8 pre installed to provide an open software operating system for software program development. This makes the UC 8. A computer an optimal solution for use with industrial applications, but at minimal cost and effort. In addition to the standard model, a 4. C wide temperature model is also available for harsh industrial environments. White Paper. Building a Future Proof Data Processing Solution with Intelligent Io. T Gateways. To date, most discussions about the Industrial Internet of Things Io. T have been about connecting new devices and rapidly bringing them online. In this white paper we look at the implications of bringing such a large number of devices online, namely, the need for efficient methods to collect information from these devices, and discuss how to handle the large amount of data collected from these devices.

EIA 2. 32 standard is one of the essential communications protocol and hardware use in many computer system installation start from small UNIX machine to the mainframe. The RS 2. 32 protocol is used by terminal such as wyse. DEC vt. 10. 0 which connected through direct cable or modem to the UNIX host or legacy system. Actually you could still tracked this history in the etctermcap file on many modern Linux distribution later on I will use this table in our project for some terminal commands information. Today the used of this port is being replaced by the Ethernet protocol and hardware for connecting to the legacy system most PCs and notebooks nowadays has replaced this port with the USB Universal Serial Bus. But in the embedded world the RS 2. In the microcontrollers world, we usually process just a small amount of data, therefore the RS 2. The RS 2. 32 devices will transmit or receive the data in the serial form and use the voltage level to differentiate between the logical 0 called Space 3 Volt to 2. Volt and the logical 1 called Mark 2. Volt to 3 Volt as seen from this following RS 2. The voltage level between 3 Volt to 3 Volt relative to the ground is considered undetermined condition. Every data transmitted or received has the format form of start bit, data bit, parity bit and stop bit the mostly used configuration with the microcontroller is 1 start bit, 8 data bit with no parity bit and 1 stop bit. The transmission speed is measured in BAUD RATE which equal to the number of bit per second for the RS 2. For example the speed of 1. Because of the different voltage level between RS 2. TTLCMOS logic used in AVR microcontroller therefore we use the voltage level shifter circuit to interface this two world. Adobe Photoshop Elements 5 Unter Windows 7. The following diagram is the commonly used circuit for this purpose the first one use two transistors Figure 1. A and the second one use the Dallas Semiconductor MAX 2. Figure 1.

The LED will be act as the programs life beacon. Therefore as log as the LED is blinking we can assure that our program is working properly. Ok lets move on to the projects C code explanation A. The ATmega. 8 UART implementation. The UART implementation is consists of three functions uartinit Initial the ATMega. UART peripheral, this will set the RS 2. Baud Rate, Data Length, Parity and Stop Bituartputch This routine will put the character directly into the UART portuartgetch This routine will read the character from the UART port. A. 1. UART initiation. The initiation of UART peripheral in ATmega. AVR ATmega. 8 datasheet on page 1. UBRRH register for the high order bits and in the UBRRL register for the low order bits according to this following formula For asynchronous normal operation mode at 1. ATmeg. 8 internal frequency oscillator of 8 Mhz, the UBRR value will be UBRR 8. The UBRR is the content of both UBRRH and UBRRL registers and must be integer from 0 to 4. In order to get the high order bits from the formula result, we have to shift 8 times to the right before assign the value to UBRRH register, while for the low order bits it will automatically cast or trimmed to the 8 bit in UBRRL register see the datasheet on page 1. UBRRH FCPUBAUDRATE1. UBRRL FCPUBAUDRATE1. Or you could simplified as. UBRRH 0. UBRRL 2. But using the first statements to assign the UBRR value to both UBRRH and UBRRL registers will be more practical because it will work in any frequency oscillator and baud rate we choose. The next step is to enable both transmit and receive port which is PIN 2 and PIN 3 in ATmega. RXEN and TXEN in the UCSRB register see the datasheet on page 1. UCSRB 1lt lt RXEN1lt lt TXEN Because we are not using the UART interrupt for both receive and transmit we just clear assigned to logical 0 the RXC1. E, TXC1. E and UDRIE bits. The RXB8 and TXB8 is use for 9 bit data length so we also clear these two bits. And the last one is to choose the RS 2. UCSRC register see the datasheet on page 1. UCSRC 1lt lt URSEL1lt lt UCSZ11lt lt UCSZ0 With this statement we set the following RS2. URSEL 1 for writing in UCSRC register. UMSEL 0 select asynchronous mode operation. UPM1 0 select parity mode disable.
