DLP2000: DLP LightCrafter with STM32 Host

Part Number: DLP2000
Other Parts Discussed in Thread: DLPC2607, DLPDLCR2000EVM

Hi,

I am trying to use the DLP2000EVM with an STM32 host processor. From the previous thread I found out that I can use a any processor which can support the RGB888 format.

I just wanted to go further verify if I can use any of the following boards from STM with my DLP2000EVM:

1. STM32F4x9 - https://www.st.com/en/microcontrollers-microprocessors/stm32f469-479.html

2. STM32F7x6/7/8/9 - https://www.st.com/en/microcontrollers-microprocessors/stm32f7x6.html

3. STM32H7A3/B3 and STM32H7B0 - https://www.st.com/en/microcontrollers-microprocessors/stm32h7a3-7b3.html

4. STM32H742/43/45/47/53/55/57 - https://www.st.com/en/microcontrollers-microprocessors/stm32h742.html

5. STM32H750- STM32H750https://www.st.com/en/microcontrollers-microprocessors/stm32h750-value-line.html

5. STM32L4+ or STM32L4R/S and STM32L4P/Q - https://www.st.com/en/microcontrollers-microprocessors/stm32l4-series.html

Can you please look into these and confirm if I can interface any of the boards with DLP?

Thank you,

Arshiya,

At minimum, the host processor you are using needs to have DPI video output (RGB888 is the default) along with I2C to send commands to the DLPC2607 controller.

Also, the native resolution of the nHD DMD is 640x360 (and it can display up to 854x480 scaled), so the host processor should be able to drive a pixel clock to support such a resolution for optimal performance.

It looks like these controllers both support RGB888 through their TFT display controllers and have a large enough pixel clock (83 MHz capable, 33.5 MHz needed) for the DLPDLCR2000EVM based on this application note:

You should be able to use the EVM with these devices.

Best Regards,

Philippe
