AVR ISP Downloader / Download Line / Programmer Support Studio 4/5/6/7 / Compatible with Original STK500

Product Description:

This programmer independently develops hardware and firmware, which perfectly supports the newly developed latest AVR studio 7; AVR studio 6.2, and V5.0 integrated development environment. It also supports the ultimate version of AVR Studio V4.19 original architecture. The AVR Studio4 series is the version most familiar to engineers who have used AVR chips in the early days. The supported chips are more comprehensive, but the update was officially stopped after V4.19 was launched in September 2011.

        AVR Studio5 and v6.X, V7.X are the preferred integrated development environment for engineers to develop AVR products in 2012. The integrated development environment integrates a C language compiler, making the development program more convenient and faster, the configuration simpler, and it can be downloaded and used for free. It is more and more preferred by the majority of AVR chip development engineers.

AVR ISP is compatible with stk500. It is an AVR microcontroller online programmer that is truly compatible with the ISP function of the official entry evaluation and programming kit stk500. The original stk500 uses the RS232 serial port to communicate with the computer and requires a separate external power adapter to work. According to the original communication protocol, we independently designed the perfect hardware and firmware that uses the USB port to connect to the computer, allowing you to work efficiently and worry-free, which is our tireless pursuit.

       AVR ISP programmer is enduring for a long time and is widely liked by AVR development engineers because it is an official programming device. When programming, the PC programming software will modify the underlying programming algorithm of the programming device online according to the ISP programming characteristics of different chips, so the wide range of supported devices, yield, and speed are unmatched by other programmers. AVR ISP is also seamlessly integrated in many development environments, such as the widely used ICC, GCC and CVAVR integrated development environments in China. You can directly call the programming function through the menu or button, and directly burn the compiled programming file into the chip. , And run, so that the development efficiency can be improved, especially when encountering products that cannot be simulated or new models of AVR chips are developed, this kind of efficient and reliable programming device is needed to verify the function of the code.

      AVR ISP supports online programming of 3.3v and 5v target boards through optimized circuit design. At the same time, the reset function is optimized. After programming the target chip, the programmer will reliably release the reset signal line and perform a reset operation. You can immediately see the result of the product running the new program, and the reset performance exceeds the original AVR ISP. The original AVR ISP sometimes fails to reset after the programming is completed.

        AVR ISP also supports the ISP programming function of the two types of microcontrollers AT89S51 and AT89S52 in the 51 series of microcontrollers.

       AVR ISP can reliably program the entire storage space of a large-capacity Flash MCU such as ATmega2560 (128K words).

Function introduction:

 1. The supported devices are shown in the following table:

 This USB AVR ISP programmer supports the same device model as the original AT AVR ISP programmer. It supports all AVR chips with ISP interface. Taking AVR Studio 4.18 SP3 as an example, it can support the following models:

 It also supports the low-voltage version of all chips in this column. V4.19 basically supports online programming of all AVR chips with ISP interface.

2. The software interface of the programmer in AVRStudio (v6.1) is shown in the figure below:

3. The operation interface for programming in AVR Studio (V4.19) is shown in the figure below :

4. The programmer correctly reads the ID picture of AT89S52 microcontroller as shown below:

5. The programming interface definition is shown in the figure below:

If the socket on the main board is designed according to the above figure, you can directly insert the ISP programming cable. The VTG pin of the plug does not supply power to the outside. The target board that needs to be programmed needs to be powered separately before performing programming related operations.

2.6. The programmer is a senior engineer for PCB layout and wiring. The product component distribution and wiring diagram are shown in the following figure:

4 common problems

4.1. Can the programmer be used in the Win7 operating system?

      Answer:: AVR studio’s V4.19, v5, and v6.1 can be used under the Win7 operating system. The USB to the serial port of this programmer also supports Win7, so the programmer can be used in the Win7 environment.

4.2. Can the programmer be used in the Win10 operating system?

      Answer: AVR studio’s V4.19, v5, v6.2, and V7.0 can be used under the Win10 operating system. The USB to the serial port of this programmer also supports Win10, so the programmer can be used in the Win10 environment.

4.3. How to deal with unsupported devices during the use of the programmer?

      Answer: this programmer is the same as the ISP programming function supported by the stk500 kit, and has been fully tested on the chips commonly used in AVR. If you encounter an AVR chip that can be supported by the STK500 through ISP in use, and the programmer cannot support it due to BUG reasons, you can send the test board back to us. We are responsible for upgrading the program to correct the firmware errors or deficiencies if it is programmed. The device cannot be programmed due to its own reasons, and the round-trip freight is paid by the manufacturer.

4.4. When the programmer is performing ISP programming operation, what causes the error of entering the programming mode when prompted?

      Answer: First reduce the ISP programming clock to 56K and then read the chip ID. If an error is still reported, it is usually because the fuse bit of the chip is incorrectly configured, which causes the ISP mode to work abnormally. Please replace it with a brand new chip. Then perform ISP function test.
