DLPNIRNANOEVM: DLPNIRNANO program inquiries

Part Number: DLPNIRNANOEVM

Tool/software:

Hello, TI technical engineer, I would like to consult the following questions when reading the program provided by Ti about DLPNIRNANO:

1）In the column scan, 228 patterns are scanned according to 3.76 step pixels in turn, how did these 228 patterns come about？

2）Why can't you scan a single pixel column, that is, 800 columns?

    Hello Chenglq,

    These patterns are generated in the TIVA.  The step size is a bit more complex than pixel width.  The wavelength size changes across the DMD so that the number of pixels per column of the scan changes.  This is determined in the algorithm.

    I do not remember what the limit is, but you can define scans with more columns.
