Re: ESP32-S3 RGB LCD maximum throughput

I believe the changes disussed in this thread are already available in IDF master branch as I am able to see below config option in the RGB panel example, CONFIG_EXAMPLE_AVOID_TEAR_EFFECT_WITH_SEM CONFIG_EXAMPLE_USE_BOUNCE_BUFFER I am working on 5" (800X480) RGB LCD. I am using the latest idf master...

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

We are good with 4" (480x480) and 4.3" (480x272) TFT LCD RGB display with ESP32-S3R8. Now, we are working on 5" (800X480) RGB LCD. I am using the latest idf master branch, Commit ID: fde4afc67a2035a1f461dc511cd85dde1ef90368 Date: 29-July-2022. We are observing glitches while the entire screen change...

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

Even with the latest master IDF (c2ccc383da), I am able to see good results with the 80MHz speed option, compared to IDF 4.4. For 120MHz and other optimization, ESP FAE has shared https://glab.espressif.cn/esp-solution/esp-lcd-rgb/esp-lcd-rgb as a current development branch and we are doing experime...

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

The PCLK frequency of LCD is 10MHz. Please find the other parameter of the LCD that we are setting to register new LCD in func esp_lcd_new_rgb_panel. esp_lcd_rgb_panel_config_t panel_config = { .timings = { .pclk_hz = 10 * 1000 * 1000, .h_res = LCD_WIDTH, .v_res = LCD_HEIGHT, // The following parame...

Re: ESP32-S3-BOX: How to get phoneme for custom voice command

Okay - Got it.
thanks for the quick response.
IMO, It should be mentioned regarding this tool in https://github.com/espressif/esp-sr/README.md.

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

I also have ESP32-S3-BOX board. When I walked through Hardware overview for the same at https://github.com/espressif/esp-box/blob/master/docs/hardware_overview/esp32_s3_box/hardware_overview_for_box.md , I found that it supports PSRAM with 120MHz of speed with octal mode. But when I checked the sdkc...

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

Hi, so, Is octal mode limited to 80MHz only? If this is the case, then I did the maximum configuration required. Still, I am getting significant delay in changing the screens or while scrolling on RGB interface display. So, Is there any solution for this? Is there any example for PSRAM optimized use...

Re: ESP32-S3 with RGB interface LCD - lagging/delay in screen rendering issue

Hi, CPU speed is already 240MHz and SPI RAM it is already configured as Octal mode. Able to set external flash speed to 120MHz but for SPIRAM(PSRAM) there is only 40 and 80 MHz option in the menuconfig. If I made it forcefully in sdkconfig file, it gives below error at compile time. In file included...
