I am trying to use a TCA6507 i2c led driver, and would like to make use of all it's features. The Datasheet and the extra documentation ( Programming Fun Lights With TI's TCA6507) are great at explaining the Select Registers (0-2) and Intensity/Timing Registers (3-8), and I can do that just fine. (Best information was from a buried page www.ti.com/expanders which references the promised but never released tca6507 evm [download has example code and gerber files])
The problem is that the last two registers are not as well explained.
Register 9, the One-Shot / Master Intensity Register BIT 6 & 7 set whether the bank 0 or bank 1 leds are set in normal or one-shot mode.
Register 10, the Initialization Register, I'm not sure I get how Bit 7 and Bit 3 work, or how the One-Shot mode takes the pins of the pwm 0 or 1.
Is there an example of the order needed to activate and use the TCA6507's one-shot mode, either from a all off point or from an existing pattern to one-shot to back to normal? The Programming/evaluation guide/evm code only look at normal mode and not one-shot mode.
(oh and I'm still interested in the evm if it ever gets released, naturally :D)
