Instructions for converting the LUFA USBtoSerial Demo to an AVR ISP Programmer.
|
||||
By Opendous Inc., Copyright under the Creative Commons Attribution License:

|
||||
|
||||
1) Start with the LUFA/Demos/USBtoSerial firmware.
|
||||
- rename USBtoSerial.c, USBtoSerial.h, and USBtoSerial.aps to
|
||||
AVRISP_Programmer.*
|
||||
- edit AVRISP_Programmer.aps and rename all instances of "USBtoSerial" to
|
||||
"AVRISP_Programmer"
|
||||
- copy AVRISP_Programmer.txt from an older version of AVRISP_Programmer
|
||||
|
||||
2) Edit makefile by changing TARGET from "USBtoSerial" to "AVRISP_Programmer"
|
||||
|
||||
3) Edit AVRISP_Programmer.h:
|
||||
- change ifdef _USB_TO_SERIAL_H to _AVRISP_PROGRAMMER_H_
|
||||
- rename ReconfigureUSART(void) to ReconfigureSPI(void)
|
||||
- add void processHostSPIRequest(void); & void delay_ms(uint8_t dly);
|
||||
- replace the define for Serial.h with one for SPI.h:
|
||||
#include <libs/LUFA/Drivers/AT90USBXXX/SPI.h>
|
||||
|
||||
4) Make alterations to Descriptors.c
|
||||
- change manufacturer string to "www.AVRopendous.org", length=19
|
||||
- change product string to "LUFA-Based AVR ISP Programmer", length=29
|
||||
|
||||
5) Edit Ringbuff.h to enable the Peek Command: #define BUFF_USEPEEK
|
||||
|
||||
6) Edit AVRISP_Programmer.c:
|
||||
- change #include "USBtoSerial.h" to #include "AVRISP_Programmer.h"
|
||||
- change BUTTLOADTAG(ProjName to "LUFA AVR910 ISP Programmer"
|
||||
- in main(), rename ReconfigureUSART() to Reconfigure();
|
||||
- in EVENT_HANDLER(USB_UnhandledControlPacket), rename ReconfigureUSART
|
||||
- delete the ISRs: ISR(USART1_RX_vect) & ISR(USART1_TX_vect)
|
||||
- delete ReconfigureUSART(void)
|
||||
- add void ReconfigureSPI(void), void processHostSPIRequest(void),
|
||||
and void delay_ms(uint8_t dly) from a previous version
|
||||
- add Timer1 and SPI initialization code to main():
|
||||

|
||||
//LEDs_Init();
|
||||
DDRB = 0;
|
||||
PORTB = 0;

|
||||
// PC2 is also used for RESET, so set it HIGH initially - note 'P' command sets it to LOW (Active)
|
||||
PORTC |= ((1 << PC2) | (1 << PC4) | (1 << PC5) | (1 << PC6) | (1 << PC7)); //AT90USBxx2
|
||||
DDRD = 0;

PORTD = (1 << PB7); // only PB7(HWB) should be High as this is the bootloader pin
|
||||
// Prepare PortB for SPI - set PB0(^SS), PB1(SCK), PB2(MOSI) as output as well as all other pins except PB3(MISO)
|
||||
DDRB = (1 << PB0) | (1 << PB1) | (1 << PB2) | (0 << PB3) | (1 << PB4) | (1 << PB5) | (1 << PB6) | (1 << PB7);

// initialize Timer1 for use in delay function
|
||||
TCCR1A = 0;
|
||||
//TCCR1B = (1 << CS10); // no prescaling, use CLK
|
||||
TCCR1B = ((1 << CS12) | (1 << CS10)); // prescale by CLK/1024
|
||||
// 8MHz/1024 = 7813 ticks per second --> ~8 ticks per millisecond (ms)

/*
|
||||
Usage:
|
||||
avrdude -vv -F -P COM7 -c avr910 -p t261
|
||||
Note -F flag which overrides signature check and enables programming
|
||||
of any "In-System Programmable via SPI Port" AVR MCU. Part number,
|
||||
t261, should be set to your target device.
|
||||
avrdude -vv -F -P COM7 -c avr910 -p t261 -U flash:w:PROG.hex
|
||||
PROG.hex is the hex file to program your t261 AVR with
|
||||
avrdude -vv -F -P COM7 -b 115200 -c avr910 -p t261 -U flash:w:test.hex
|
||||
The -b 115200 sets the SPI clock to 62.5kHz from the default 125kHz and may
|
||||
work when the default programming speed fails.
|
||||
AVROSP.exe -dATtiny261 -cCOM7 -rf
|
||||
AVRosp is the Open Source AVR ISP Programming Software available from Atmel.com
|
||||
|
||||
Note: on Linux systems, COM7 should be replaced with someting like /dev/ttyACM0
|
||||
You can determine this value by running dmesg after plugging in the device
|
||||
Note: you must RESET the programmer after each use (AVRdude session).
|
||||
|
||||
Note: If you experience errors with older devices, try changing the DELAY defines
|
||||
|
||||
MISO, MOSI, and SCK are connected directly from the AVRopendous board
|
||||
to the pin of the same functionality on the target. RESET pin on the target
|
||||
can be connected either to SS (PB0), or PC2. Do not have any other pins
|
||||
connected - especially HWB pin, to avoid unintentional behaviour.
|
||||
|
||||
AVR910 functionality was overlayed on USBtoSerial functionality.
|
||||
Keep this in mind when looking over the code.
|
||||
Default target speed is 125kHz and corresponds to 19200 baud, which
|
||||
is the default setting for AVRdude.
|
||||
|
||||
Changing "Baud-Rate" will change the SPI speed. Defualt SPI clock speed
|
||||
is 8Mhz / 4 = 2MHz. 8Mhz is the device clock speed. This is the setting at
|
||||
9600 baud. The following is a table of baud-rate vs. SPI Speed that will result
|
||||
9600 = 2Mhz
|
||||
14400 = 1MHz
|
||||
19200 = 125kHz (AVRdude Default)
|
||||
38400 = 250kHz
|
||||
57600 = 500kHz
|
||||
115200 = 62.5kHz
|
||||
|
||||
Before running, you will need to install the INF file that
|
||||
is located in the project directory. This will enable
|
||||
Windows to use its inbuilt CDC drivers, negating the need
|
||||
for special Windows drivers for the device. To install,
|
||||
right-click the .INF file and choose the Install option.

|

*
|
||||
* Communications Device Class demonstration application.
|
||||
* This gives a simple reference application for implementing
|
||||
* a USB to Serial converter using the CDC class. Data communicated
|
||||
* over the USB Virtual Serial Port according to Atmel's AVR910
|
||||
* protocol is used to program AVR MCUs that are
|
||||
* "In-System Programmable via SPI Port".
|
||||
*
|
||||
* After running this firmware for the first time on a new computer,
|
||||
* you will need to supply the .INF file located in this demo
|
||||
* project's directory as the device's driver when running under
|
||||
* Windows. This will enable Windows to use its inbuilt CDC drivers,
|
||||
* negating the need for custom drivers for the device. Other
|
||||
* Operating Systems should automatically use their own inbuilt
|
||||
* CDC-ACM drivers.
|
||||
*
|
||||
* Usage:
|
||||
* avrdude -vv -F -P COM7 -c avr910 -p t261
|
||||
* Note -F flag which overrides signature check and enables programming
|
||||
* of any "In-System Programmable via SPI Port" AVR MCU. Part number,
|
||||
* t261, should be set to your target device.
|
||||
* avrdude -vv -F -P COM7 -c avr910 -p t261 -U flash:w:PROG.hex
|
||||
* PROG.hex is the hex file to program your t261 AVR with
|
||||
* avrdude -vv -F -P COM7 -b 115200 -c avr910 -p t261 -U flash:w:test.hex
|
||||
* The -b 115200 sets the SPI clock to 62.5kHz from the default 125kHz and may
|
||||
* work when the default programming speed fails.
|
||||
* AVROSP.exe -dATtiny261 -cCOM7 -rf
|
||||
* AVRosp is the Open Source AVR ISP Programming Software available from Atmel.com
|
||||
*
|
||||
* Note: on Linux systems, COM7 should be replaced with someting like /dev/ttyACM0
|
||||
* You can determine this value by running dmesg after plugging in the device
|
||||
* Note: you must RESET the programmer after each use (AVRdude session).
|
||||
*
|
||||
* Note: If you experience errors with older devices, try changing DELAY_LONG
|
||||
* to a larger value, such as 0xFF in AVRISP_Programmer.c
|
||||
*
|
||||
* MISO, MOSI, and SCK are connected directly from the AVRopendous board
|
||||
* to the pin of the same functionality on the target. RESET pin on the target
|
||||
* can be connected either to SS (PB0), or PC2. Do not have any other pins
|
||||
* connected - especially HWB pin, to avoid unintentional behaviour.
|
||||
*
|
||||
* AVR910 functionality was overlayed on USBtoSerial functionality.
|
||||
* Keep this in mind when looking over the code.
|
||||
* Default target speed is 125kHz and corresponds to 19200 baud, which
|
||||
* is the default setting for AVRdude.
|
||||
*
|
||||
* Changing "Baud-Rate" will change the SPI speed. Defualt SPI clock speed
|
||||
* is 8Mhz / 4 = 2MHz. 8Mhz is the device clock speed. This is the setting at
|
||||
* 9600 baud. The following is a table of baud-rate vs. SPI Speed that will result
|
||||
* 9600 = 2Mhz
|
||||
* 14400 = 1MHz
|
||||
* 19200 = 125kHz (AVRdude Default)
|
||||
* 38400 = 250kHz
|
||||
* 57600 = 500kHz
|
||||
* 115200 = 62.5kHz

NOTE: The user of this include file MUST define the following macros
|
||||
prior to including the file:
|
||||
|
||||
MAG_T1_CLOCK_PIN Pin connected to Track 1 clock wire (ie. PORTC1)
|
||||
MAG_T1_DATA_PIN Pin connected to Track 1 data wire (ie. PORTC2)
|
||||
MAG_T2_CLOCK_PIN Pin connected to Track 2 clock wire (ie. PORTC3)
|
||||
MAG_T2_DATA_PIN Pin connected to Track 2 data wire (ie. PORTC0)
|
||||
MAG_T3_CLOCK_PIN Pin connected to Track 3 clock wire (ie. PORTC5)
|
||||
MAG_T3_DATA_PIN Pin connected to Track 3 data wire (ie. PORTC6)
|
||||
MAG_CLS_PIN Pin connected to card loaded wire (ie. PORTC4)
|
||||
MAG_PIN PIN macro for the reader's port (ie. PINC)
|
||||
MAG_DDR DDR macro for the reader's port (ie. DDRC)
|
||||
MAG_PORT PORT macro for the reader's port (ie. PORTC)
|
||||
|
||||
The example macros listed above assume that the Track 2 data wire is
|
||||
connected to pin 0 on port C, the Track 2 clock wire is connected to
|
||||
pin 3 on port C (similarly for Tracks 1 and 3), and the card loaded
|
||||
wire is connected to pin 4 on port C.
|
||||
|
||||
If the magstripe reader you are using only reads one or two tracks,
|
||||
then set the clock and data pins for the tracks it doesn't read to a
|
||||
pin that is unused. For example, on the AT90USBKey, any of the pins on
|
||||
port C that do not have wires attached will be unused since they are
|
||||
not connected to any onboard devices (such as the joystick or
|
||||
temperature sensor).
|
||||
|
||||
Connecting wires to pins on different ports (ie. a data wire to pin 0
|
||||
on port C and a clock wire to pin 0 on port D) is currently
|
||||
unsupported. All pins specified above must be on the same port.
