Arduino and AVR (avrdude) projects

Headless build

The sketches can be build without starting the Arduino frontend:

  • Edam's arduino.mk makes building easy using the Arduino source package, it only needs a pointer to the current Arduino folder.

  • mkdoc Rules.mk is used for the rest, uploading, downloading, flashing bits, building docs, etc.

  • Example:

    $ make arduino P=Mpe/Blink B=atmega328p
$ make upload I=Mpe/Blink/Blink.hex C=m328p M=arduino

    Read the source for more on the parameters.

  • I uses AVRISP mkII to upload sketches to m328p, using an USB BUB II module (w/ FTDI TF232RL chip).

  • Alternatively, the JeeNode is used as ISP using JeeLab's Flash Board to upload bootloaders.

  • Libraries are scanned for based on name, to inlude 'myLib.h' the file must be in

Arduino/AVRdude

Arduino NG (Nuova Generazione)
  • An USB board with ATmega8, later ATmega168.
Diecimilla "10.000"
  • Celebration of 10.000 boards. Has an ATmega168 on it. PDIP.
Duemilanove "2009"
  • First an ATmega168, then ATmega328p. PDIP.
UNO
  • USB board. Now at rev3. PDIP.
JeeNode
  • Six versions, all 3.3v. The mainline is compatible with Duemilanove, and later with Uno (OptiBoot 0.44). [1]

8, 168 and 328 are pin-compatible, but have different hardware. The same seems to go for mega 16/32/644/1284?

avrdude:

avrdude
  -U <memtype>:r|w|v:<filename>[:format]

The easiest upload for Arduino land is using a bootloader. This makes the chip accepts new program code over an serial connection. Usually a FTDI device, and you have all you need to wire up and program an AVR of atmega series. To cover more ground, an USBasp is everything needed to wire up and flash AVR uC's without bootloader (yet).

The avrdude commands I need are in Rules.old.mk. For compiling, arduino.mk does the job OK and I don't mess with it much.

The avrdude protocol usually is arduino.

Baudrates do matter. Sometimes -B is needed to lower the clock speeds in order to catch attention of an slower running chip.

Here are my alternatives of serial bootloader aided uploads:

Protocol Baudrate Device
Arduino (328/2009) 57600 Generic FTDI
Arduino ISP 19200 +Arduino or compatible
Uno (optiboot?) 115200 "

Remember running ATmega328P at 3.3v/16Mhz is out of specs already.

Have not tried HV programming. Ie. 12V. Not really needed to, but have a untested programmer build in progress so maybe.

USBisp mx-usbisp-v3.00

I'm not sure if the delivered device is supposed to do anything, I cant test it outside of Linux, and I'm pretty sure it's not doing anything there.

  • an tiny Atmega8L USB package with colored slide on metal cover and AVR isp compatible header IDC header. Came with about 60cm flatcable.
  • Blue and red onboard SMT LEDs, under a milimiter sized hole drilled in the aluminium cover. At arduino pins 14 (blue) and 15 (red).
  • Modded: added two buttons, one to reset, one to enable reprogramming the application (using USBaspLoader, to reflash bootloader another USBasp module is used). Attaching program switch does not look feasible at all, need need to use USBaspLoader bootloader image with timeout setting.
  • modded: removed surplus GND header pins (that would normally alternate the MOSI, MISO, and SCK cores in a flat cable) and nc pin, with intention to route SDA/SCL and TX/RX, but chip is to small to solder. At least connector is compatible with other USBasp mods.
  • Cannot be modded further than adding reset. SPI pins available only, chip is too small.
  • Usable for arduino projects with SPI and USB toys.

  • Programmed using another USB module, an usbasp from betemcu:

    avrdude -v -p m8 -c usbasp -U hfuse:w:0xC8:m -U lfuse:w:0xBF:m
  -U flash:w:firmware/betemcu-usbasp/alternate_USBaspLoader.2010-07-27_configured_for_betemcu/firmware/hexfiles/alternate_USBaspLoader_betemcu_timeout.hex
  -U lock:w:0x0F:m

  • Now it accepts any program using arduino protocol, e.g. vusb_mouse_example.hex which turns the stick into a mouse device that slowly circles the cursor over your screen.

  • It can be turned into an usbasp programmer itself by uploading the original firmware to flash again:

    avrdude -v -p m8 -c usbasp -U flash:w:mx-usbisp-v3.00-flash.hex

    Just press the reset, note that blue led lights up and then start avrdude.

More info with ouroboros project using USBaspLoader.

USBasp betemcu-usbasp-miniprog MiniProg
  • from betemcu.cn, Atmega8L TQFP. Yellow led (D4) at m8 PC0: and red (D3) at PC1.
  • Moddable to route I2C/TWI (SDA/SCL) and serial (TX/RX). Additional routes with glued on female jumper strip (16 extra pins should be enough for almost all spare atmega pins).
  • no suitable project box or cover.
  • upon connecting the jumper for reprogramming, the device is no longer recognized as usbasp.

  • Problem: different behaviours upon reflash.

  • Using two new betemcu's, one soldered to be reprogrammed. Verify using make verify-betemcu, yields these fuses:

    hfuse:0xd9
    lfuse:0xff
    lock:0x3c

    The same fuse results for usbasp or arduinoisp. However the eeprom memory dump is different. This is the betemcu image: <file://./firmware/betemcu-usbasp/usbasp_atmega8l_eeprom-betemcu_download.hex> Appearantly not needed, so excluding.

  • Also writing these settings on a previous (already modded) betemcu the fuse bits won't "stick" make upload-betemcu:

    • lfuse 0xff reads out as 0xbf
    • hfuse 0xd8 reads 0xc8
    • lock is okay (0x3c).

    The problem seems independent of programmer. Strangely though one stick reads lock 0x3f?

    After a little investigating it turns out I might have to unlock and then lock before writing flash, as indicated by project ouroboros post.

  • Using previous observation, updated make upload-betemcu. Will now erase, and set lock bit to value given in ouroboros project for avrdude (0x3F). Then a second run to flash and set fuses, and then lock the lock bit. The first erase, and turning of erase on second flash-write may be important, its left untested.

    unlock:0x3F
    lfuse:0xFF
    hfuse:0xD9
    lock:0x0F

    This now enables reflashing a betemcu USB stick to usbasp using both JeeNode isp_flash (Arduino ISP) and another betemcu usbasp.

    I am using the firmware given by the ouroboros downloads. It is frustrating but my own download looks like garbage. Maybe also something to do with the fuses. A bit of fiddling suggest then -e flag together with the unlock is needed, and rereading/verifying the flash might be impossible.
