LVGL 8.3.7 & ESP-IDF 5.2 #222

Ok.. so I got my SSD1306 OLED display working again... See https://github.com/hiruna/lv_port_esp32/tree/develop/lvgl_8.3.7_idf_5.2 for the
Added https://github.com/hiruna/lv_port_esp32/blob/develop/lvgl_8.3.7_idf_5.2/sdkconfig.ssd1306 for reference |

128x128 ST7735 LCD is somewhat working... trying to figure out why the rendering is off the screen bounds 🤔 (what I have : http://www.lcdwiki.com/1.44inch_Arduino_SPI_Module_ST7735S_SKU:MAR1441)
|

Tested lvgl benchmark, 128x128 display is obviously too small but good to see it working

Got my hands on a ILI9341 3.2" 320x240 display w/ touch. (http://www.lcdwiki.com/3.2inch_SPI_Module_ILI9341_SKU:MSP3218) Touch panel was not connected/tested in this test. ESP32 CPU Speed: 240MHz Pins: CLK -> GPIO14
MISO -> GPIO12
MOSI -> GPIO13
LED -> GPIO26
DC -> GPIO27
RST -> GPIO33sdkconfig used: https://github.com/hiruna/lv_port_esp32/blob/develop/lvgl_8.3.7_idf_5.2/sdkconfig.ili9341

My ILI9341 3.2" 320x240 touch panel has a HR2046 instead of a XPT2046 but I configured it as a XPT2046 and it works for me. sdkconfig: https://github.com/hiruna/lv_port_esp32/blob/develop/lvgl_8.3.7_idf_5.2/sdkconfig.ili9341_touch |

Tested with Waveshare GC9A01 240x240 round display module sdkconfig: https://github.com/hiruna/lv_port_esp32/blob/develop/lvgl_8.3.7_idf_5.2/sdkconfig.GC9A01

got my self a Freenove esp32s3 (N8R8) and a 1.9inch 170×320 LCD Display Module (ST7789V2) (https://www.waveshare.com/1.9inch-lcd-module.htm) 262K colors are supported by display but LVGL doesnt have the option also had to set spi dma chan to auto (got an error saying chan 1 was not supported by the chip, maybe this is not for everyone ?) - hiruna@f22026c added offsets for the 170x320 display - hiruna@16f9f93

Ported https://github.com/jakpaul/lvgl_touch_calibration via my fork at https://github.com/hiruna/lvgl_touch_calibration. PR submitted to @jakpaul with my changes. Updated https://github.com/hiruna/lv_port_esp32/blob/develop/lvgl_8.3.7_idf_5.2/main/main.c to cater for the touch calibration.

Hi Hiruna [edit: just noticed the original is still on lvgl v7x so probably issue there, not here] just a status report I tried this branch grafted onto https://github.com/mhaberler/m5core2_esp-idf_demo.git , modified from ropg using bleeding edge IDF 5.2 this works fine except for the touch controller, which I still have to look into - looks like the FT6X36 is found and properly initialized (see below), but needs some love to actually report ;)
I'm primarily interested in M5Stack Core2 and CoreS3 so dabbling with those great job!
ps: complete boot log: |

Hi @mhaberler , I don't own a M5Stack/(display with FT6X36 touch controller) but if you enable verbose logging via the sdkconfig (since I set touch point reporting to verbose only via 50b212a) [it improves performance when it's not always outputting logs per touch], you should be able to see the full log output. you can set the default log level to debug via the |
|
If you want a more complete set of drivers for the Core 2, you might want to start here: https://github.com/m5stack/Core2-for-AWS-IoT-Kit/tree/BSP-dev You can turn off features that only exist on the AWS version for the standard Core2 (e.g. secure module and sidebar LEDs) using menuconfig options. Might be a better starting point and I'd love to push that to support IDF 5.2 and the latest LVGL. Happy to review a pull request and merge it into that branch if it works well. |

@rashedtalukder thanks, appreciated! |

@hiruna thanks for this port. I have a ESP32-2432S032C board and it basically works. There was one major blocker: it seems that Also the display orientation seems mirrored and inverted. I'm not sure I got the right fix but changing the |

is this compatible with esp32c3? |
Hi all,
I got IDF v5.2 (master) & LVGL 8.3.7 to compile.
See https://github.com/hiruna/lvgl_esp32_drivers/tree/develop/lvgl_8.3.7_idf_5.2
I only have a SSD1306 128x64 OLED display and a 128x128 ST7735 LCD but focusing on the SSD1306 OLED for now.
Will add a branch for the
lv_port_esp32soon, the main.c needs some tweaking (Only included changes for the SSD1306 hello world,lv_demo_*functions will need changes too):static lv_disp_buf_t disp_buf;->static lv_disp_draw_buf_t disp_buf;lv_disp_buf_init(&disp_buf, buf1, buf2, size_in_px);->lv_disp_draw_buf_init(&disp_buf, buf1, buf2, size_in_px);disp_drv.buffer = &disp_buf;->disp_drv.draw_buf = &disp_buf;lv_obj_t * label1 = lv_label_create(scr, NULL);->lv_obj_t * label1 = lv_label_create(scr);lv_obj_align(label1, NULL, LV_ALIGN_CENTER, 0, 0);->lv_obj_align(label1, LV_ALIGN_CENTER, 0, 0);Compilation & flashing succeeds but my OLED display shows garabge (pixel noise), I'm thinking something's wrong with the i2c_manager ?
Feel free to test this branch out and let me know how it is.
