DLPLCR4500EVM: Unable to project from selected flash index using Python

Hexin Joseph

Part Number: DLPLCR4500EVM

Tool/software:

I have 3 BMP Images in Indexes 0,1,2 and I want to project in the order shown in the image. Using the GUI I am able to project in the expected order.

Using Python I am unable achieve the desired sequence. Kindly clarify on the following

1) For pattern configuration using Pattern Display LUT Control (2.4.3.4.5) what should I give for Number of LUT entries and Number of Image Index LUT Entries. Also clarify what determines this.

2) Kindly correct if there is anything I miss in my steps, as i am not able to reproduce the results as GUI. The steps I follow currently are:

Open Mailbox with value 1
Set Mailbox offset 0
Set image indices for 0,1,2
Close Mailbox
Open Mail with value 2
Set Mailbox offset 0
Define Pattern as trig_type=0, pat_num=0, bit_depth=8, led_select=0b001, do_buf_swap = True
Set Mailbox offset 1
Define Pattern as trig_type=0, pat_num=1, bit_depth=8, led_select= 0b100, do_buf_swap = False
Set Mailbox offset 2
Define Pattern as trig_type=0, pat_num=2, bit_depth=8, led_select= 0b010, do_buf_swap = True
Set Mailbox offset 3
Define Pattern as trig_type=0, pat_num=0, bit_depth=8, led_select=0b001, do_buf_swap = True
Define Mailbox offset 4
Define Pattern as trig_type=0, pat_num=1, bit_depth=8, led_select= 0b100, do_buf_swap = False
Define Mailbox offset 5
Define Pattern as trig_type=0, pat_num=2, bit_depth=8, led_select= 0b010, do_buf_swap = False
Validate and start the sequence

3) The main issue I am facing is the images is not loaded from the correct flash index; can you clarify how this exactly works because we do not define the image index anywhere.

4) I find a function Load Image (2.3.4.6). What is the use of this and should i use it anywhere for my requirement.

5) Is there a way I can load the .ini file in python and use
