The 'r' command for bus pirate reads a single byte, so r:16 is attempting to read 16 bytes, not 16 bits. I'd guess you want "r:2 r:2" (or just "r:4") But, I doubt that's the problem. If it had worked, you'd have seen the 4 bytes then some FFs. I think it's more likely that your chip is not ready to accept commands over SPI.

The Bus Pirate expects xxxx+1 data bytes. Up to 16 data bytes can be sent at once. Note that 0000 indicates 1 byte because there’s no reason to send 0. First one, 0xDE, which bus pirate also finds when using (1)-command (see pic below) is a write address.

This guide is intended to be a quick overview and cover a few things not explicitly covered in the Bus Pirate documentation provided by … Update 19th April 2012 - I finally go an ATmega2560, so I fixed the code to work with memory paging and also updated the patches to work with all the latest versions of AVRDUDE and the Bus Pirate firmware. Update 12th January 2013 - Haven’t touched this stuff in a while, but a reader informed me that the patch no longer works with the latest SVN. 2016-08-25 The 'r' command for bus pirate reads a single byte, so r:16 is attempting to read 16 bytes, not 16 bits.

2014-12-06 · The bus pirate. I would like to run the LP directly with the LCD but there is a problem. I don’t want to mess with code then find out that my soldering was dry. So I chose to use the Bus Pirate. For thos who dont know, the bus pirate is a small tool that can be used with most serial bus protocols to debug and analyse them.

USB transmit indicator. This LED flashes when there's traffic from the PIC to the PC. 3. Power indicator. A long enough stream of data will eventually overtake the buffer, after which new bytes will be dropped until space is available.[] Both sniffers use the user input buffer as a ring buffer. Any commands entered after the sniffer macro will be lost. If the ring buffer is full, bytes are simply dropped until there’s free space.
One “program” command writes to one 256-Byte page (e.g. 0x012300 to 0x0123ff). The chip buffers the data you send in its internal RAM, and programs the whole page after you end the command by unselecting the chip. Erase command resets whole 4096-Byte blocks to 0xFF so that you can program them again. Bus Pirate
Any commands entered after the sniffer macro will be lost. If the ring buffer is full, bytes are simply dropped until there’s free space. The Bus Pirate has a built-in address scanner that checks every possible I2C address for a response.
This should eliminate problems with dropped bytes, regardless of UART speed or display mode. Warning! Enter sniffer mode before connecting the target!!
