ESP32 TFT display library

[kearins]

Why did you commented out call to gpio_set_level() in spi_master_lobo.c?

Code: Select all

//gpio_set_level(handle->cfg.spics_ext_io_num, 0); 
GPIO.out_w1ts = (1 << handle->cfg.spics_ext_io_num);

In this case we can't use GPIO 32,33 for PIN_NUM_DC. Maybe you have a reason to do so?

I uncommented call to gpio_set_level in 2 places and modified two defines in tftspi.c:

Code: Select all

//#define DC_CMD	GPIO.out_w1tc = (DC_VAL)
//#define DC_DATA	GPIO.out_w1ts = (DC_VAL)
#define DC_CMD	gpio_set_level(PIN_NUM_DC,0)
#define DC_DATA	gpio_set_level(PIN_NUM_DC,1)

and successfully tested demo with definition:

Code: Select all

#define PIN_NUM_DC 33

Why did you commented out call to gpio_set_level() in spi_master_lobo.c? ...

If I remember well, it runs slightly faster that way..
I'll check it and try to make pins 32,33 usable. Thanks for reporting.

Hello loboris,

would it be feasible to also display PNG images? They tend to be cleaner than JPG and much smaller than BMP.

Dear all，

I copied component.mk from https://github.com/loboris/ESP32_spiffs_example (components\mkspiffs\component.mk and components\spiffs_image\component.mk). But, I can't execute "make flashfs" and "make makefs" yet.
Who can help me? Thanks.

[我从 ESP32_spiffs_example 中拷贝了 component.mk 文件，但是在执行"make flashfs"和"make makefs"时仍然报错，请帮忙分析，谢谢！]

Code: Select all

Did you try this receipt?

Yes. I test this library under Win10.
The steps are as follow:
1) Clone the repository

Code: Select all

git clone --recursive https://github.com/espressif/esp-idf.git
git clone https://github.com/loboris/ESP32_TFT_library.git
git clone https://github.com/loboris/ESP32_spiffs_example.git

2) Copy "component.mk" to "ESP32_TFT_library/components/spiffs_image" from "ESP32_spiffs_example/components/spiffs_image"
copy "component.mk" to "ESP32_TFT_library/components/mkspiffs" from "ESP32_spiffs_example/components/mkspiffs"
3) Modify "ESP32_TFT_library/components/spiffs_image/Makefile.projbuild"

Code: Select all

.PHONY: flashfs makefs copyfs

4) Replace the whole directory 'ESP32_TFT_library\components\mkspiffs' with 'ESP32_spiffs_example\components\mkspiffs'
5) Execute 'make menuconfig', select 'Running on ESP-WROVER_KIT' and configure 'Default serial port'
6) Ececuting 'make clean','make flash' and 'make copyfs' are ok.
But, I can't execute "make flashfs" and "make makefs"
Can you help me fix the error? Thank you!

Can you help me fix the error? Thank you!

Have you got environment variable OS? Run the command:

Code: Select all

set OS

What value will be shown on the screen?

Hi，kearins:
The issues were solved when I updated the toolchain. Thanks a lot for your due attention to my post.
到官网更新toolchain后这个问题得以解决

[kearins]

loboris,
the library does not print text by TFT_print() in esp-idf commits 845c3fb (22 sep 2017) and 050ae50 (08 sep 2017). Also there are some artefacts on screen. It looks like DMA transfer does not work correctly.

The esp-idf commit with which the library works fine is 5539bfb (07 aug 2017)

I have the fix for that issue ready, it will be pushed today or tomorrow.
