Thanks for the UART and SPI decoding! They both works and they are a great asset during product development.
I really think they should pay back to you in terms of new scopes sold.
There are a few points for improvement.
1. The UART gets confused if the chars are comming without time spacing. This is a problem.
2. The excel export (only tried SPI) a data sheet. This data sheet has too much "looking pretty" formatting. The time should not be exported with "1.2us" or "3.5ns". The time unit should be in a separate cell.
I already have a new project that will need both UART and SPI. Great gear.
