# AVR In-System Programming over WiFi for ESP8266
This library allows an ESP8266 module with the HSPI port available to become
an AVR In-System Programmer.
## Hardware
The ESP8266 module connects to the AVR target chip via the standard 6-pin
AVR "Recommended In-System Programming Interface Connector Layout" as seen
in [AVR910](http://www.atmel.com/images/doc0943.pdf) among other places.
If the AVR target is powered by a different Vcc than what powers your ESP8266
chip, you **must provide voltage level shifting** or some other form of buffers.
Exposing the pins of ESP8266 to anything larger than 3.6V will damage it.
Connections are as follows:
ESP8266 | AVR / SPI
--------|------------
GPIO12 | MISO
GPIO13 | MOSI
GPIO14 | SCK
any* | RESET
For RESET use a GPIO other than 0, 2 and 15 (bootselect pins), and apply an
external pullup/down so that the target is normally running.
## Usage
See the included example. In short:
```arduino
// Create the programmer object
ESP8266AVRISP avrprog(PORT, RESET_PIN)
// ... with custom SPI frequency
ESP8266AVRISP avrprog(PORT, RESET_PIN, 4e6)
// Check current connection state, but don't perform any actions
AVRISPState_t state = avrprog.update();
// Serve the pending connection, execute STK500 commands
AVRISPState_t state = avrprog.serve();
```
