Type A is the port on the computer (the host). The ports on the peripheral or mobile device are Type B, Mini USB, Micro USB or Lightning. Before USB-C was introduced, Type A ports were found on every computer. Today, laptops are increasingly using only USB Type C, which is expected to eventually replace all USB connectors. See USB and USB Type C. سیدمحمداسماعیل مدنی سیدمحمداسماعیل مدنی Mon, 08 Mar 2021 04:47:46 +0330 https://virgool.io/@smem/usb-avr-programmer-hax2kdrvabt8 USB AVR Programmer for Atmel AVR microcontrollers. USB AVR Programmer is made of an Atmega8 and few components. The programmer uses a firmware driver that makes this programmer attractive to many amateurs. Another thin why this programmer is so popular is because it is officially included and supported in WinAVR. Once again lets see what this programmer is made off and how to set it up. The core of USB AVR Programmer adapter is Atmega8 microcontroller clocked by 12MHz crystal. Soldered board is ready to be connected via simple USB cable with B type connector (Computer side needs A type of connector). Resistors R2 and R6 are current limiting resistors, that protect computer USB port. Resistor R7 helps computer to recognize device as LS (Low Speed). Diodes D1 and D2 indicates about data transfer. Header SV1 is compatible with STK200/300 just 4 and 6 pins are used for RXD and TXD (may be used for other purposes). سیدمحمداسماعیل مدنی سیدمحمداسماعیل مدنی Fri, 05 Mar 2021 16:27:52 +0330 https://virgool.io/@smem/hello-world-sik05eoxy1lk While small test programs have existed since the development of programmable computers, the tradition of using the phrase "Hello, World!" as a test message was influenced by an example program in the seminal 1978 book The C Programming Language. The example program in that book prints "hello, world", and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial:main( ) { printf("hello, world\n");} سیدمحمداسماعیل مدنی سیدمحمداسماعیل مدنی Thu, 04 Mar 2021 13:56:51 +0330
