DLP3010EVM-LC: If the GUI software "DLP Pico Display and Light Control" support any other chips that has the same function as the MSP430F2274IDAR and CY7C6521

Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLPC3478, , DLPC-API

Hello,

I want design my own board using DLPC3478 like DLP3010EVM-LC.

As we know, the main board of the DLP3010EVM-LC contains the two chips CY7C65215-32LTXI and MSP430F2274IDAR, which are essential for the communication between the demo board and the GUI software "DLP Pico Display and Light Control". I want to use other kind of chips in my design, but at the same time that should be able to support the GUI software.

What I expected is as below:

1) the  USB-Serial Dual Channel chip CY7C65215-32LTXI  --> Any other chip that suport USB-IIC and USB-SPI.

2) the MCU MSP430F2274IDAR --> Any other chip in MSP430F series.

I will appreciate it very much if anyone tell me whether the GUI software "DLP Pico Display and Light Control" support any other chip that has the same function.

    Hello,

    The Cypress chip (CY7C...) is used as the USB to SPI and USB to I2C interface. As far as the DLPC3478 controller is concerned, it only needs to receive the appropriate I2C commands and the Cypress IC isn't required. However, the GUI expects the Cypress IC. I will have to see if the advanced mode of the GUI supports additional options. If not, you would have to develop your own interface to convert your front end USB commands to the I2C commands supported by the DLPC3478 (either from scratch or starting with the DLPC-API). 

    The MSP430 is utilized to configure the ITE front end IC (for HDMI input) and assist with a handshake protocol. While not strictly needed for the DLPC3478 itself, the GUI likely expects it. However, any IC that replicates the functionality should be acceptable. You can download the MSP430 code here and see a guide discussing the commands at 1033.EVM I2C Access.pdf. 

    Thanks,

    Kyle

    Hello,

    I have confirmed the advanced mode of the GUI either needs the Cypress IC (with or without the MSP since the handshake can be disabled) or a Devasys device. For other options the GUI wouldn't support it but the controller could still be used if you wrote your own software.

    Thanks,

    Kyle

    I thought so at first, but I'm not sure. But now I'm clear.

    Thanks!
