Hello michu. Thanks for the last two links. The new information on the wiki is much improved and very useful.
I still experience problems with uploading the firmware to the rainbowduino through the arduino. The error I get is the following:
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x95
avrdude: failed to write flash memory, rc=-4
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xf1
I got this when sending the firmware pde file by using the arduino022 ide. The wiring is now as follows:
VCC-5v
GND-GND
RESET-DTR
RX-RX
TX-TX
Therefore I am now no longer trying to power the rainbowduino through the JST connection.
I do first load an empty sketch on the arduino and I do select the duemilanove 328 device on the IDE.
My devices connect to a usb port on a MacBook Pro. I dont know if the IDE on MAC OS could have any issues that is why I am mentioning it. Also sometimes usb ports dont output the voltages/amps as the usb specification mentions. Maybe laptops are worse than desktop pcs?
Do you know any people that have managed to flush a rainbowduino through an arduino where both devices have the ATMEGA328 chip installed on them? I already spend about 150-200 dollars on electronics equipment + other on this project and if possible I would like to avoid spending another £15 on a UartSB (unless if this is the only option).
Thanks,
M
