When using the buspirate to send and receive spi Is it possible to display all the MOSI/MISO data, i.e. full duplex spi.
I’m debugging a board with some chips i’ve never worked with before. I’m sending commands, [0x25 r:7] but i want to see what the first spi word out is. Also it would be good to be able to control what the dummy read word (i.e. 0xff) is.

Hi ilw,
Yes, you can use { instead of [ and it will show the byte read while writing. That also gives you control over what byte is sent when you want to read.

Hmm. The documentation says
[ - send the START condition for the currently selected bus mode. { - send the alternate START condition for the currently selected bus mode.
I’m not sure I understand the difference. I had assumed they were synonyms.

That should get some clarification. In the general sense { is an alternate start condition, but specifically you need to check the protocol bus commands to see what the functions are. I’ll push an update, thank you for the heads up.
Yes please. I searched for “Alternative Start” in the documentation and only found that one reference. Thank you.

Pushed, should be live in a second.

Hey @GPIOexpander2 - It looks like your firmware may be out of date. Update to the latest and you should see something like this with an SPI EEPROM:
