As I know, DMD pixels could be parked by project control via composer, but the parked state can not be set for each pixel individually.
Is it possible to control and set on(+12°), off(-12°) and parked(0°) state for each pixel individually?
If yes, how to achieve that? Does it available in project control or need to modify source code?
If DLP4500NIR does not support this function, is there any other DMD product support that?
Hi Daisy,
Welcome to the E2E forums with your questions.
I believe there is only two states of the mirrors, the on (unparked state) or off (parked state) of the pixels. For example the universal DMD park or unpark signal as per DLPC350 programmers guide only shows parked or unparked. (https://www.ti.com/lit/pdf/dlpu010)
In relation to individual pixel control, I believe this is possible see these other E2E links:

Hi Alex,
Thanks for reply, but I am confuse about the definition of parked state. In the DLP4500NIR datasheet, parked state is defined as 0 degree. please refer to the below picture.
To avoid misunderstanding, I use flat state (0 deg) rather than parked state to clarify my question.
My question is that is it possible to make some pixels stay in flat state (0 deg) and others stay in on or off state?
Could I let input light be reflected to three different directions by controling tilt angle of each pixel? For example, let some pixels stay in on state, some pixels stay in flat state and the other pixels stay in the off state.
