I am programming avr microcontrollers using avrgcc and avrdude . If am specifying wrong controllers then avrdude throws error message syaing wrong device signature. Is there an avrdude method from which i can find which controller is it connected to like Atmega8,Atmega324,Atmega644 etc. Then it would be easy to change the avrdude command with respect to the controller reply am getting.
So my first idea was to combine a microcontroller with a GSM and a GPS modul. There are a lot of these modules over at Sparkfun, for example. Looking through their shop I found the Telit GM862, which is a GSM modul with an built in GPS receiver. That is what I wanted. And they sell great break out boards to make it easier for hobbyist to access these modules.

Looking at the specs for the GM862, you realize, that it is more complex as you might have thought. A problem for me, still a beginner in electronics, were the different voltages used for the module. The power supply has to be 3.4-4.2V. Thats ok as an AVR can run on that voltage. But the serial port requires lower levels, 2.8V (CMOS). That means, you can not connect the UART of the controller directly to the module. You have to do some level translation. Fortunately this has already been solved over at Trackbox2.
I want to make project Virtual Lab....In this project hardware kit(AVR kit) is connected to college PC.But student can program it from its home via internet. So it is require that ,Student can load there HEX file into controller from far end.Further more camera is attached to college PC which adhere to hardware kit.So,student can analyze whats going on...Other good idea regarding this project is appreciate...
Yes it is, but as pointed out the protocol to download a hex file to the AVR controller seems to be quite involved. If it is fully documented by AVR you can of course try to implement it in LabVIEW but I would expect this to be non-trivial.
Look at attach image i am able to load program into Avr controller using labview.Now i am trying to load program over internet remotely .Now when i am trying to load program over internet i am giving path into LOAD HEX button.But this path is consider as server path..
I'm programming an ATmega32 chip, and have set some bits as 1 in some DDRs and PORTs. In case I forget what bits I had set to 1, is there a way to set all the register bits to a value(1 or 0) that was present in the registers when I had bought the chip. I mean I want to do a factory reset of the micro-controller. Is it possible to do it in program or AVRDUDE with USBasp or any other means that doesn't require me to buy additional hardware?
AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.
AVR microcontrollers find many applications as embedded systems. They are especially common in hobbyist and educational embedded applications, popularized by their inclusion in many of the Arduino line of open hardware development boards.
Atmel says that the name AVR is not an acronym and does not stand for anything in particular. The creators of the AVR give no definitive answer as to what the term "AVR" stands for.[3] However, it is commonly accepted that AVR stands for Alf and Vegard's RISC processor.[4] Note that the use of "AVR" in this article generally refers to the 8-bit RISC line of Atmel AVR microcontrollers.
Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET), but other than that the pinout was identical.
The AVR 8-bit microcontroller architecture was introduced in 1997. By 2003, Atmel had shipped 500 million AVR flash microcontrollers.[8] The Arduino platform, developed for simple electronics projects, was released in 2005 and featured ATmega8 AVR microcontrollers.
The ATmega series features microcontrollers that provide an extended instruction set (multiply instructions and instructions for handling larger program memories), an extensive peripheral set, a solid amount of program memory, as well as a wide range of pins available. The megaAVR 0-series (released in 2016) also has functionality such as:
Atmel's AVRs have a two-stage, single-level pipeline design. This means the next machine instruction is fetched as the current one is executing. Most instructions take just one or two clock cycles, making AVRs relatively fast among eight-bit microcontrollers.
The AVR instruction set is more orthogonal than those of most eight-bit microcontrollers, in particular the 8051 clones and PIC microcontrollers with which AVR competes today. However, it is not completely regular:
The mostly regular instruction set makes C (and even Ada) compilers fairly straightforward and efficient. GCC has included AVR support for quite some time, and that support is widely used. LLVM also has rudimentary AVR support. In fact, Atmel solicited input from major developers of compilers for small microcontrollers, to determine the instruction set features that were most useful in a compiler for high-level languages.[7]
AVRs have a large following due to the free and inexpensive development tools available, including reasonably priced development boards and free development software. The AVRs are sold under various names that share the same basic core, but with different peripheral and memory combinations. Compatibility between chips in each family is fairly good, although I/O controller features may vary.
The Program and Debug Interface (PDI) is an Atmel proprietary interface for external programming and on-chip debugging of XMEGA devices. The PDI supports high-speed programming of all non-volatile memory (NVM) spaces; flash, EEPROM, fuses, lock-bits and the User Signature Row. This is done by accessing the XMEGA NVM controller through the PDI interface, and executing NVM controller commands. The PDI is a 2-pin interface using the Reset pin for clock input (PDI_CLK) and a dedicated data pin (PDI_DATA) for input and output.[18]
debugWIRE is Atmel's solution for providing on-chip debug capabilities via a single microcontroller pin. It is particularly useful for lower pin count parts which cannot provide the four "spare" pins needed for JTAG. The JTAGICE mkII, mkIII and the AVR Dragon support debugWIRE. debugWIRE was developed after the original JTAGICE release, and now clones support it.
The STK600 allows in-system programming from the PC via USB, leaving the RS-232 port available for the target microcontroller. A 4 pin header on the STK600 labeled 'RS-232 spare' can connect any TTL level USART port on the chip to an onboard MAX232 chip to translate the signals to RS-232 levels. The RS-232 signals are connected to the RX, TX, CTS, and RTS pins on the DB-9 connector.
The JTAGICE mkII debugging tool supports on-chip debugging (OCD) of AVRs with SPI, JTAG, PDI, and debugWIRE interfaces. The debugWire interface enables debugging using only one pin (the Reset pin), allowing debugging of applications running on low pin-count microcontrollers.
The very popular AVR Butterfly demonstration board is a self-contained, battery-powered computer running the Atmel AVR ATmega169V microcontroller. It was built to show off the AVR family, especially a then new built-in LCD interface. The board includes the LCD screen, joystick, speaker, serial port, real time clock (RTC), flash memory chip, and both temperature and voltage sensors. Earlier versions of the AVR Butterfly also contained a CdS photoresistor; it is not present on Butterfly boards produced after June 2006 to allow RoHS compliance.[42] The small board has a shirt pin on its back so it can be worn as a name badge.
The AVR Butterfly comes preloaded with software to demonstrate the capabilities of the microcontroller. Factory firmware can scroll your name, display the sensor readings, and show the time. The AVR Butterfly also has a piezoelectric transducer that can be used to reproduce sounds and music.
The Arduino physical computing platform is based on an ATmega328 microcontroller (ATmega168 or ATmega8 in board versions older than the Diecimila). The ATmega1280 and ATmega2560, with more pinout and memory capabilities, have also been employed to develop the Arduino Mega platform. Arduino boards can be used with its language and IDE, or with more conventional programming environments (C, assembler, etc.) as just standardized and widely available AVR platforms.
Schneider Electric used to produce the M3000 Motor and Motion Control Chip, incorporating an Atmel AVR Core and an advanced motion controller for use in a variety of motion applications but this has been discontinued.[51]
Microcontrollers using the ATmega architecture are being manufactured by NIIET in Voronezh, Russia, as part of the 1887 series of integrated circuits. This includes an ATmega128 under the designation 1887VE7T (Russian: 18877).[58]

I have not had to rely upon the estlcam restore operation, but it sounds like something is off. You should be able to reflash your cm controller to grbl 0.9 and take it from there. You could also consider flashing to grbl 1.1 be457b7860
