AVR910 Class Reference

Constructor.

Parameters:

mosi	mbed pin for MOSI SPI line.
miso	mbed pin for MISO SPI line.
sclk	mbed pin for SCLK SPI line.
nReset	mbed pin for not reset line on the ISP interface.

Sends an enable programming command, allowing device registers to be read and commands sent.

Definition at line 43 of file AVR910.cpp.

Program the AVR microcontroller connected to the mbed.

Sends a chip erase command followed by writing the binary to the AVR page buffer and writing the page buffer to flash memory whenever it is full.

Parameters:

binary	File pointer to the binary file to be loaded onto the AVR microcontroller.
pageSize	The size of one page on the device in words. If the device does not use paged memory, set this as the size of memory of the device in words.
numPages	The number of pages on the device. If the device does not use paged memory, set this to 1 (default).

Returns:

0 => AVR microcontroller programmed successfully. -1 => Problem during programming.

Definition at line 87 of file AVR910.cpp.

Read the part family and flash size of the device.

Returns:

Code indicating the family of AVR microcontrollers the device comes from and how much flash memory it contains. 0xFF -> Device code erased or target missing. 0x01 -> Device is locked.

Definition at line 230 of file AVR910.cpp.

Read the part number.

Returns:

Code identifying the part number. 0xFF -> Device code erased or target missing. 0x02 -> Device is locked.

Definition at line 245 of file AVR910.cpp.

Read the vendor code of the device.

Returns:

The vendor code - should be 0x1E for Atmel. 0x00 -> Device is locked.

Definition at line 215 of file AVR910.cpp.

Set the frequency of the SPI communication.

(Wrapper for SPI::frequency)

Parameters:

frequency

Frequency of the SPI communication in hertz.
