Hi,

Please find following init sequence for ILI9163C LCD.

/// SPI Init LCD ILI9163C Sequence
static const ili_init_cmd_t ili_init_cmds[]={
{0x01, {0}, 0x80},
{0x11, {0}, 0x80},
{0x3A, {0x66}, 1},
{0x26, {0x04}, 1},
{0xF2, {0x01}, 1},
{0xE0, {0x3F, 0x25, 0x1C, 0x1E, 0x20, 0x12, 0x2A, 0X90, 0x24, 0x11,
0x00, 0x00, 0x00, 0x00, 0x00}, 15},
{0XE1, {0x20, 0x20, 0x20, 0x20, 0x05, 0x00, 0x15, 0xA7, 0x3D, 0x18,
0x25, 0x2A, 0x2B, 0x2B, 0x3A}, 15},
{0xB1, {0x08, 0x08}, 2},
{0xC0, {0x14, 0x02}, 2},
{0xC1, {0x02}, 1},
{0xC5, {0x1D, 0x4A}, 2},
{0xC7, {0xCA}, 1},
{0x2A, {0x00, 0x00, 0x00, 0x7F}, 4},
{0x2B, {0x00, 0x00, 0x00, 0x9F}, 4},
{0xEC, {0x0C}, 1},
{0x36, {0xC8}, 1},
{0x29, {0}, 0x80},
{0x2C, {0}, 0x80},
{0, {0}, 0xFF},
};

The Dimension for this LCD is 160 X 128 and I have checked using SPI Master example in which it is working fine without any issue.

I will also check with your updated GIThub demo and will provide you an update regarding that.

So, You can also add support of that into your existing demo. Let me know if need any help for that.

Hi Loboris,

Hope You are doing well.

Can you please let me know that is there any support for "horizontal/vertical window scrolling functions" in your current firmware git repository specific to TFT Library?

We have checked into whole TFT Library but not found any APIs or reference for that and also we have tried with our own way as well but not got proper mechanism for both window scrolling.

Let me know if you have any idea for that.

I have plans to implement scrolling functions, hardware scrolling is easy to implement, but I'm working on on a combination of software/hardware scroling which should have more features.

All future additions and changes related to TFT will be available in my new repository https://github.com/loboris/ESP32_TFT_library

Thanks for quick update.

Let me know once you add support for scrolling features into your current repository which you have mentioned in your last reply.

Hi Loboris,

I have one more quick question for you that is there any plan to add support for PNG file format in addition to ".jpg" and ".bmp" file format your latest TFT Repository?

We have one requirement in which we want to use transparent image and that image format is in .png format.

So, Please let me know if you have any plan for that.

@Ritesh

Yes, I'm planning to include PNG support.
At the moment I'm looking for the best way to implement transparency.
As I'm not using the frame buffer (it will be included later for ESP32 with 4MB of PSRAM) the data has to be read from display RAM, combined with image data and written back to display RAM.
I'm also planning to implement a kind of transparency also for BMP and JPG images, where you have ta manually declare the transparent color.

So, when that support will be added in your current latest Repository?

Any tantative schedule or date for that?

Hi Loboris,

Will you please let me know your schedule or any tantative schedule to add support for PNG image format in to your existing Repository?

Let me know if you have plan to add it soon.
