8048S043 capacitative touch buttons not working in demo

[rzeldent]

Discussed in #189

^{Originally posted by ralphrmartin August 14, 2024}
I have a problem on an 8048s043 board, bought as having capacitative touch. It has both a GT911 chip and an xpt2046 chip.
The board as supplied had a demo running on it iwhich iworked OK, including touch (which does indeed seem to be capacitative as it responded to a light touch), but when I try the eap32-smartdisplay-demo program, touch does not work correctly (whether I select 8048S043C or 8048S043R). The display is drawn correctly, but the buttons to add 1 and to rotate do not function.

On enabling debugging, the display" jumps" whenever I press either button, but they still do not work as intended. The debugging information shows the below.

Can anyone enlighten me as to what is going wrong here?
(Why is the SDK version: v4.4.7-dirty?)

Thanks.

i have esp32-8048s043C no xpt2046, only gt911
ST7262 RGB

'.pio/libdeps/esp32-8048S043C/esp32_smartdisplay/src/lvgl_panel_st7262_par.c:101:10: error: 'esp_lcd_rgb_panel_config_t' has no member named 'on_frame_trans_done'
.pio/libdeps/esp32-8048S043C/esp32_smartdisplay/src/lvgl_panel_st7262_par.c:102:10: error: 'esp_lcd_rgb_panel_config_t' has no member named 'user_ctx'

where is on_frame_trans_done, user_ctx ?

ps. I also have the screen jumping problem.

ex) LVGL

lv_display_set_buffers(disp, disp_draw_buf, NULL, bufSize * 2, LV_DISPLAY_RENDER_MODE_PARTIAL); // is OK.

lv_display_set_buffers(disp, disp_draw_buf, NULL, bufSize * 2, LV_DISPLAY_RENDER_MODE_DIRECT); // screen moves every time touch

Hi DevAny,

Strange it does not compile. Are you using the coorrect version of LVGL? Otherwise take a look at the develop branch.

I only uses partial updates. It might be possible that complete updates work but the framerate will be very low and this can lead to problems. It can also be that the parameters PCLK etc need to be tweaked.

Hope I gave you some useful info ...
