DLP5530PGUQ1EVM: Control EVM

Part Number: DLP5530PGUQ1EVM
Other Parts Discussed in Thread: DLP5530Q1EVM, DLPC230-Q1

Hello -

1）How to control EVM without dlpc230 control program? Do you have any relevant schemes for directly sending commands to control EVM?

2）When sending command APIs through cheetah, is it an API function passed directly? Can I understand it as: if I send directly commands to EVM without the "dlpc230 control program", I can directly send the string of relevant API functions?

If I understand wrong, please correct me!

Thanks，

yang

    Hello Yang -

    The DLP5530Q1EVM controller board has both a Host SPI and Host I2C communication connector port. You can connect either one of these in order to communicate with the DLPC230-Q1.

    For details on the I2C and/or SPI protocol, please refer to the DLPC230 Programmer's Guide: https://www.ti.com/lit/dlpu041

    Note that we do not have an API available at this time, so you will need to develop your command interface protocol according to the Programmer's Guide.

    Regards,

    Ross

    Hello -

    I have learned about the host SPI communication connector port. I want to know whether the commands in your command library are sent when communicating with dlpc230-q1 through SPI. Can you point out the commands in the command library for me?

    In other words, regardless of the SPI protocol, what information should I transmit to dlpc230-q1 to control it. 

    You should explain to me how each command is defined, not how to send it. 

    I hope I have made my meaning clear!

    Thanks，

    Hello Yang -

    I am not sure I understand. All of the information you need should be included in the Programmer's Guide.

    Let's consider an example of changing the Dimming Level value via SPI.

    Using the Command Log of the ACP tool, we can see what a command setting the Dimming Level value to 30,000 (7530h) looks like:
