Please also verify that the avrdude command is as expected for your device. $ git clone -recursive git:///urjaman/frser-duino -b arduino-mega-1280įor the Mega2560, change the Makefile to target the correct MCU (replace 1280 with 2560). $ git clone -recursive git:///urjaman/frser-duinoĪs above, except use the branch for the 1280:

The avr toolchain(avr-gcc, avr-libc,make etc.).

This page used to link to serprog-duino, frser-duino should build in a similar fashion and has better serial buffering and some other features (spi speed setting).

A recent flashrom with the serprog protocol compiled in (most packaged versions do).

These to be used like the FTDI at 2Mbaud: fast-usbserial. If you use the appropriate make target, but there exists a firmware that allows The frser-duino firmware works around this by default Have lots of bugs in their usb-serial firmware that prevent it from operating at more The Arduino Uno R3 and other arduinos with an ATmega8U2/16U2 as an usb-serial converter

For LPC/FWH, current (16/02/01) flashrom trunk will be really slow, please use this branch instead.

the PD7 used as LPC CLK clashes with BT reset in BT arduinos.

Note: do check for any incompatibilities between your arduino and the shield, eg.

Frser-duino does have the code for using the CS like in this shield, but you need to modify spihw.h.

This shield uses a different pin for SPI CS than the other circuits on this page, and has LPC/FWH capability, thus different firmware.

The Uno R3 will work with the fast-usbserial U2 firmware.

This shield and firmware was built for 5V ATMega328s with FTDI, variations to that will need adaptations in building the shield and/or in the firmware.

The DIL-8 and SOIC-8 versions connect like this:įirmware and hardware sources Shield PCB shared at oshpark The 3rd version is using the DIP16 HEF4050 buffer chip: Here's one with 5 resistors, the downside is that you'll need to modify the The part count for the resistor divider is 6 resistors of 2 types or 9 of one type. One thing to remember about the resistor dividers is that they're not strong enough There are a few options here, ranging from the simple resistors (v1) to a buffer chip (v3). The idea is that you pick one version from each part 1 through 3, There are some simple schematics included here ( source). 1.8V conversion isnt covered here, yet.The FTDI based usb-serial converters are the fastest.a 3.3V SPI flash chip that is supported by flashrom.a way to convert the 5V logic levels to 3.3V (except if 3.3V arduino, these are rarer).

Arduino Mega or Mega2560, but notice that the software has a different branch for them.any based on the ATmega328 (/168/88 will work with small changes too), like the Arduino Uno R3.3 Alternative: Shield with SPI and LPC/FWH for 5V Arduinos.
