CrowPanel 7" Display DIS08070H will not compile Demo Lessons 4, 5 or 6
Hello,
I'm having difficulties compiling the demo lesson #6, CrowPanel_ESP32_LVGL_Demo. The truncated IDE error message is:
/Arduino/CrowPanel_ESP32_LVGL_Demo/CrowPanel_ESP32_LVGL_Demo.ino: In function 'void setup()':
/CrowPanel_ESP32_LVGL_Demo.ino:95:7: error: 'class PCA9557' has no member named 'reset'
Out.reset();
^~~~~
CrowPanel_ESP32_LVGL_Demo.ino:96:7: error: 'class PCA9557' has no member named 'setMode'; did you mean 'pinMode'?
Out.setMode(IO_OUTPUT);
- additional compile errors pointing to PCA9557 -
The Arduino IDE is setup with the following.
Using board 'esp32s3' esp32/2.0.15
Using core 'esp32' esp32/2.0.15
LVGL 8.3.11
TFT_eSPI 2.5.0
Lovyangfx 1.1.8
PCA9557-arduino 1.0.0
SPI 2.0.0
Wire 2.0.0
Using CrowPanel 7" display DIS08070H V3.0
Any help you could provide would be greatly appreciated.

Found the issue. You must use Elecrow PCA9557 file provided.
Hi,
Could you get any of the demo code working ? Maybe the GIU or Drawing board Demo ?
Even after the solution you discovered, I still get errors during compile..
May I request you to send any of the demo code (not your main code) working for you?
It will be most helpful in finding out whee I'm going wrong.
Thank you!
roycejp,
I'll try to help you out. In the "CrowPanel_ESP32_Tutorial" files I'm using the examples found in folder "7.0 v3.0 touch new code". This is because my display is a version v3.0. If you're using a different version, this won't work.
Let's focus on example 4, "crowpanel-esp32-7.0-3.0-touch" found under folder "4". When you compile the code using Arduino IDE, what specific errors are you receiving?

Hi,
Thanks a lot for replying.
I have created a new discussion for my issues.
I have posted my results for (new) lesson 4 there.
Can you please check out my update there?
Thank you!
I tried to link the discussion, but it seems i'm not allowed to do that.
The discussion is:
"Strange Error when compiling Lesson 4 (Drawing board) 7 inch V3.0"
Its around the 10th from the top.
BTW did you use the old lessons with the new library, or the new lessons ?
I would be happy if I could just get the simpler old lessons working.
Can you just help me to get lesson 2 (Draw.ino) working ?
My version is 3.0
I'm already using the new libraries provided.
Thank you!
