T-Display-S3 and ESP-IDF v5.0 #103

Closed KamranAghlami closed 1 year ago

KamranAghlami commented 1 year ago

Hey everyone!

I've been pulling my hair out in few past days trying to get the display working, I have done it in IDF v4.4 (https://github.com/KamranAghlami/T-Display-S3.git) but for some reason I can't figure it out in version 5.0, I'm a software guy with relatively limited knowledge of hardware.

Thought I'd ask here if any one has done it or has any idea why my code isn't working. I'll copy my example code which is based on esp32's i80 display example.

Thanks in advance

Can you attach the output log information? It allows us to combine code judgments to find problems.

I read carefully several times, but couldn't find the crux of the problem. I'm going to tag it, hope someone in the know can help.

KamranAghlami commented 1 year ago

Thanks for spending time on this, I'm looking forward for some help as well.

NhiepPhongPTT commented 1 year ago

I have the same error as you. I fixed it by copying the entire esp_lcd folder in the components of ESP-IDF v4.4.4 to the corresponding path of ESP-IDF v5.0.1 (../esp-idf/components/esp_lcd)

KamranAghlami commented 1 year ago

hmmm, It's nice to know doing that fixes the issue, but it's far from ideal to revert to an old version of the SDK specially when it's a major one. It's a good starting point to figure out what has changed to fix the actual issue though. 👍

NhiepPhongPTT commented 1 year ago

You can give feedback to the ESP-IDF team so they can fix it in a later version while we can use the older version. The ESP-IDF version is still the best version with only one component in it being old. If you want to find out specifically where the error is, just check the programs related to initializing the lcd, this is not difficult but it will take time.

Sure, It's something that I'd like to see resolved myself. Regarding your question, not really, since I can't confirm it's an IDF issue in the first place.

@KamranAghlami Could you show me the OUTPUT LOG part when the program crashed and got rebooted? The part with Guru Meditation Error... I believe I have the same issue although I used another I2C sensor in my case

I'm not sure which crash/reboot you are referring to, my sample never crashes

KamranAghlami commented 1 year ago

Weird thing is if I touch sides of the board some times I get an screen refresh with the correct color but wrong shape and at wrong position, I'd say It's a signal corruption but It's how and why is beyond me.

hoffmajs commented 1 year ago

I might have found a fix: I also had an issue with the display of the T-Display-S3 when using ESP-IDF v5 framework.

I had working examples with arduino, however in esp-idf the display remaind black or showed garbage. While examining the code from the arduino examples, I found that they configured PIN_LCD_RD (gpio 9) as output and set it to high. Searching for that, I found a post on the Espressif forum where someone wrote that PIN_LCD_RD should be driven high (by setting it to input with pullup) even though the bus driver itself does not use the pin, but if it is driven low, it would impact the transfer.

So I added: `

define PIN_LCD_RD 9

const gpio_config_t input_conf = {
    .pin_bit_mask =  1ULL << PIN_LCD_RD),
    .mode = GPIO_MODE_INPUT,
    .pull_up_en = GPIO_PULLUP_ENABLE
};
ESP_ERROR_CHECK(gpio_config(&input_conf));

` just before setting up the bus (where PIN_NUM_POWER is set high). With that, I got the display working in esp-idf v5.

Thanks @hoffmajs - that solved the issue for me.

KamranAghlami commented 1 year ago

Thanks @hoffmajs, that was it, can't believe I missed that. 🤦‍♂️ 👍

krupis commented 1 year ago

@KamranAghlami Hello. Sorry for reopening this closed issue but I would like your help getting the T-Display S3 to work. What I did:

  1. Open the esp\esp-idf\examples\peripherals\lcd\i80_controller example project
  2. Replace all the code with the your code in your first comment
  3. In the menu config, the following example settings are selected: image

  4. Added 

    .mode = GPIO_MODE_INPUT,
.pull_up_en = GPIO_PULLUP_ENABLE,
.pin_bit_mask =  1ULL << PIN_LCD_RD
};
ESP_ERROR_CHECK(gpio_config(&input_conf));

    In app main.

  5. Succesfully built and flashed the T-Display S3 (without touch) module

The device is constantly rebooting due to failed to init external RAM:

Is your example not running on T-Display S3 board? Do you have your custom board with external ram?

UPDATE

I have disabled the Support for external, SPI-connected RAM in menuconfig: image

and managed to start the program without any resets:

Hi @krupis.

If you're getting a 32x32 square flashing black and white it's working as intended.

This line is drawing a 32x32 square at position (32, 32) and buff is switching between buf1 (black) and buf2 (white), rest of screen isn't being drawn so it contains random data.

esp_lcd_panel_draw_bitmap(panel_handle, 32, 32, 64, 64, buff);

Oh. I didint realize that! Thanks a lot for clarifying.

I have a lot of difficulty understanding how to use display functions to draw anything useful. For example, if I want to display text on the top left "Random number:" and then random number generated for example: "Random number:15"

Do you plan to use LVGL?

KamranAghlami commented 1 year ago

Sure, no problem.

I'd like to try that but as of now I'm not sure when that would be, I'm quite busy at the moment.

If using older version of IDF with Arduino and PlatformIO is an option for you, I have an example here which utilizes lvgl that you might want to try.

Thanks, il have a look.

One more thing - did you look into how to get touch display to work on esp-idf?

According to lilygo documentation, they use: image

But the esp-idf only supports: image

The version I've got is the non-touch version, I'm not sure, If IDF doesn't natively support that chip you have to roll your own driver for it. I'd check if any of those chips that IDF supports are similar to yours, maybe you'll get lucky.

It took me some work to get this working with the latest versions of espidf and lvgl. This thread helped me figure some things out.

I packaged everything up as clean an minimally as possible and published it to a project repo. Hope it helps somebody out. There are a couple things I'd like to figure out and improve and I'll keep it up to date as I'm able while it's relevant to my work. Thanks!
