لطفا بگوئید چگون با ای سی at76c711می توان کار کرد در ضمن دیتا شیتش را خواندم اما چیزی متوجه نشدم

اکر زحمتی نیست یک پروژه که این ای سی در ان به کار رفته را به من معرفی کنید که یک نمونه برنامه نیز برای این

ای سی نوشته شده با شد.

با تشکر فراوان

با سلام من

اين آي سي رو تو اينترنت گشتم اما پيداش نكردم

چيه ديتا شيت شو بذلر ببينيم چيه ؟؟؟

ببخشين آره پيداش كردم يه ميكرويي هست كه بر پايه risc و مثله at90usb هستش اما سرعت ساپوت usb زياده چون at90usb ورژن 1.0 رو ساپورت مي كنه احتمالا اين ورژن 2.0 رو ساپورت كنه شما اين آي سي رو دارين كه مي خواهين با هاش پروژه بسازين يه خورده مطلب گذاشتم


San Jose, CA - October 25, 2000 - Atmel Corp. today released a universal serial bus (USB) to universal asynchonous receivertransmiter (UART) bridge controller (AT76C711) based on its 8-bit AVR microcontroller. The AT76C711 can be used in applications where peripherals supporting fast serial asynchronous or synchronous transfer of data have to communicate with a host or other peripherals through a high-speed serial link like USB, the company said.

The AT76C711, running up to 24 MHz, is designed to provide high-speed USB interface to devices that need to communicate with a base station through fast serial links like UARTs and IrDA interfaces. The AT76C711 has two UARTs, one that can be used as an IrDA interface and an integrated USB interface with a devoted DMA controller. The DMA controller is able, under firmware control, to transfer data between the dual port random access memory (DPRAM) and the UART, without intervention of the processor, the company said.


Segmentation and Reassembly (SAR) of the transmitted and received packets through the UART are also executed with the aid of the DMA controller under firmware control. Other features, besides a high-speed 8-bit microcontroller and 3K Bytes of DPRAM that make the AT76C711 attractive is the 2K Bytes of SRAM for data storage, 8K x 16-bit in-system SRAM for program code and on-chip boot strap ROM for program uploading.


"With computers slowly phasing out the RS-232 interface, many customers will need a vehicle that allows them to bridge these gap stated," Richard Bisset, product marketing director for Atmel multimedia & communications. "Our AT76C711 is a part that can benefit various applications, USB to UART bridge, USB to IrDA bridge and two UARTs multiplexed into a high speed USB uplink to name just a few. To allow customers to evaluate this part, we have an Evaluation Kit (AT76C711-EK) that is also offered as a reference design."


The AT76C711 comes in a 64-pin TQFP package and is currently in production. In high volume, the AT76C711 is priced at $4.85. The Evaluation Kit, AT76C711-EK is priced at $149.00.

سلام
این میکرو توسط کامپایلر win avr ساپورت می شه که من کتابخانه اون می ذارم البته این بگم توابع اون نیست و کلیه رجیستر ها برای بکار بردن اون در کامپایلر هست شما یک جستجو در موردش بکن البته + win avr]


اینم بگم ورژن جدیدش باید باشه یعنی 20080402rc1
اینم توضیحات در مورد win avr
