This is an example how to upload a program to the ATtiny13 microprocessor so that it will act as a stand-alone computing device. An example is playing jingle bells.
Contents |
Have
- an ATtiny13
- an ft232r chip
- a program for the ATtiny13, e.g. beep.hex
- SUSE Linux 12.2. Other distributions may work similar, but you are on your own
Know
The ATtiny13 looks like this:
------
PB0(MOSI)-|ATtiny|-GND
PB1(MISO)-| 13 |-
PB2 (SCK)-| |-
VCC-| o|-RES
------
Do
- install some dependencies needed to build avrdude:
yast -i bison flex gcc make
- install an avrdude update as described here: http://doswa.com/2010/08/24/avrdude-5-10-with-ftdi-bitbang.html
- Connect MISO from the ATtiny 13 with RXD from the FT232R, and make more connections. In the end it must look like this:
------
RTS-|ATtiny|-GND
RXD-| 13 |-
TXD-| |-
VCC-| o|-DTR
------
- connect the FTDI chip with the computer
- unload the ftdi driver:
rmmod ftdi_sio
- test if avrdude works. Tell it to output the hfuse:
tweedleburg:~/at/avrdude-5.10 # ./avrdude -cft232r -pt13 -P/dev/ttyUSB0 -U hfuse:r:-:h -B 1 avrdude: BitBang OK avrdude: pin assign miso 1 sck 0 mosi 2 reset 4 avrdude: drain OK ft245r: bitclk 4800 -> ft baud 2400 avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.00s avrdude: Device signature = 0x1e9007 avrdude: current erase-rewrite cycle count is -158 (if being tracked) avrdude: reading hfuse memory: Reading | ################################################## | 100% 0.01s avrdude: writing output file "<stdout>" 0xeb avrdude: safemode: Fuses OK avrdude done. Thank you.
- seems to work. Now upload blink2.hex:
tweedleburg:~/at/avrdude-5.10 # ./avrdude -cft232r -pt13 -P/dev/ttyUSB0 -U flash:w:blink2.hex -B 1
Now draw RES and the thing will start blinking :)))
Know-how
This does not fit into this article any more but I found it out: Read the flash:
tweedleburg:~/at/avrdude-5.10 # ./avrdude -cft232r -pt13 -P/dev/ttyUSB0 -U flash:r:-:h -B 1
TroubleShooting
- Symptom
avrdude: /dev/ttyUSB0 open failed
- Solution
Unload the driver blocking /dev/ttyUSB0, in my case: modprobe -r ftdi_sio
