* while sleep deprived for a super constrained mcu
|

*
|
||||
* some bugs fixed for defcon 32 on aug 6-7, 2024
|
||||
*
|
||||
* driver assumptions:
|
||||
* - rows and columns are used in order on the chip, lowest to highest
|
||||
* (if any are skipped, just skip this data in your buffer)
|
||||
* - duty cycle will be set according to the column count
|
||||
* - all AW20xxx chips will operate on the same i2c bus
|
||||
* - the only i2c write routine does not have register arguments
|
||||
*
|
||||
* driver notices:
|
||||
* - updates only happen one column at a time, and are blocking
|
||||
* (future version may implement a callback when each column is done)
|
||||
* - this driver has not yet implemented the pattern controller
|
||||
* - this driver has not yet implemented the GAIN register, so only operates 8-bit
|
||||
* (will be implemented later to allow for beyond-8-bit operation)
|
||||
* - this driver has not yet implemented FADEDIM mode
|
||||
* - all transfers result in copies of data, which is wasteful
|
||||
* (future version may transfer LED data directly from the buffer)
|
||||
*
|

* if you need anything different, write it yourself
