Bus Pirate Development / Re: Firmware v5.6
I got one simple idea. When we got servo signal generator. Why we would not upgrade it to full PPM generator, so you can feed RC transmitter for wireless servo control. what do you think?

Bus Pirate Development / Re: Firmware v5.0 to do
This is example from console...

SPI> [0x40 0xa1 0xc0 0xa6 0xa2 0x2f 0xf8 0x00 0x27 0x81 0x10 0xac 0x00 0xaf]
CS ENABLED
WRITE: 0x40
WRITE: 0xA1
WRITE: 0xC0
WRITE: 0xA6
WRITE: 0xA2
WRITE: 0x2F
WRITE: 0xF8
WRITE: 0x00
WRITE: 0x27
WRITE: 0x81
WRITE: 0x10
WRITE: 0xAC
WRITE: 0x00
WRITE: 0xAF
CS DISABLED

And my proposal is

SPI> [0x40 0xa1 0xc0 0xa6 0xa2 0x2f 0xf8 0x00 0x27 0x81 0x10 0xac 0x00 0xaf]
CS ENABLED
WRITE: 0x40 READ: 0x01
WRITE: 0xA1 READ: 0x02

Bus Pirate Development / Re: Firmware v5.0 to do
Hello everyone

just playing with one SPI device on my bench and i have found out that there is one thing which i miss.

When I write data to device, in SPI mode, you should receive another byte, so I would appreciate that this byte is displayed, ideally after command.

For example:

WRITE: 0x40 RECIEVED: 0x01

This is very usefull, when device operates in "window" mode...

Bus Pirate Support / Re: AVRdude vs. BP is very slow
So it is way too slow in general...and switchning firmware is annoying ;(

But i have seen some log, where reading ID took about 0,02s it means five time faster then in my case. Ana author of suppor for avrdude Michal Ludvig said that his PB acts fast and without any delays...

Bus Pirate Support / AVRdude vs. BP is very slow
I'm having troubles with speed of programing AVR targets with AVRdude and BP. Everything works fine, but slow. Changing in -x spifreq=0..7 makes no change at all. This is debug out from my console

And loading of 6.8kb hex file takes about 120s ;((

Any ideas?
