ebi demo

[syl2019-he]

Is there any mdk project of EBI demo bare machine?

[yachen]

Hi, here's application demo code. We'll push EBI driver to BSP later. Thanks. main.txt

[syl2019-he]

谢谢 tank you ！！！  Whether there is an example of using PDMA driver to generate EBI data

You can refer to PDMA_BasicMode sample in BSP and set the source/destination address to EBI address space to read/write EBI space.

tanks ！！！，Let me test the EBI + PDMA routine

[yachen]

Driver's out in 09f28d7. Pls update attached main. Thanks. main.txt

[yachen]

Did you pull 09f28d7?

[syl2019-he]

Thank you for seeing that the EBI example has to be 32-bit access 16bits doesn't seem to respond when writing data

[syl2019-he]

What does ebi1 write data16 look like

[syl2019-he]

Tanks I tested successfully

Examples of ucosiii and keil5 rtx-v2

[syl2019-he]

Which chip does keil 5 project choose to develop the ARM9 chip of Toshiba chosen by your example

[yachen]

We don't support ucosiii and keil5 rtx-v2. You can use Toshiba TMPA900CMXBG or any other ARM926EJ-S processor.

[syl2019-he]

tank you！！！

How to set up EBI to support LCD 80 mode? Is there a test example

[syl2019-he]

EBI and PDMA fail to pass the test. I don't know what causes the failure of data transmission of PDMA

[syl2019-he]

EBI uses PDMA to drive clock waveform. There are several subtle delay clocks that are not continuously output. How to optimize clock continuity

[syl2019-he]

[syl2019-he]

PDMA + EBI intermediate interval time is a little long. Can we find out whether the time can be reduced optimally

[yachen]

Hi, Please try again with max burst size (128 transfer).

[syl2019-he]

I've set the burst mode of the PDMA to 128 bytes, but there's still so much time between no effects

[syl2019-he]

pdma设置.txt

[syl2019-he]

Let me see if the PDMA settings are correct

[yachen]

Hi, you set transfer count to 1. Please set this value as large as possible. (Max is 65536). PDMA_SetTransferCnt(SRAM_MDMAx_STREAM,SRAM_MDMAx_CHANNEL, pdma_struct.pdma_width, 1);

[syl2019-he]

PDMA_SetTransferCnt(SRAM_MDMAx_STREAM,SRAM_MDMAx_CHANNEL, pdma_struct.pdma_width, 1);      There's no data in the beginning

  Setting it to 1 is just the beginning of initialization

I don't seem to have any improvement when I modify the PDMA parameters

[yachen]

Hi,

In a Non-OS environment, CPU can get better EBI throughput than PDMA. To maximize the EBI + PDMA throughput, please use scatter gather mode and set max transfer count.

Sincerely,

Yi-An Chen

[syl2019-he]

I am using the FreeRTOS operating system project to do the development

[syl2019-he]

You can test how my EBI + PDM Project generated data comes from a few microseconds in the middle. The data of my PDM Project is 512 bytes

[syl2019-he]

You can test how my EBI + PDM Project generates data with a few microseconds in between. Actually, my data with a PDM is 512 bytes with a few microseconds in between every 16 clocks

[mrajeshanalogics]

HELLO, CAN YOU PLEASE SHARE THE SAMPLE PROGRAM FOR 16 BIT EBI FOR NUC980DK NON-OS bsp. @yachen @syl2019-he

[ychuang3]

We re-added the EBI_SRAM sample code. Please pull the up-to-date bsp.

[syl2019-he]

Does EBI+SRAM support pdma for accelerating read speed and improving read and write speed of SRAM
