Unable to compile demo code or any code using PxMatrix library

[Vihang-Patil]

Hello,
I have downloaded the PxMatrix library 1.8.1 on my 2 laptops
I want to implement scrolling display on p10 led module using ARDUINO MEGA or ESP32 (not decided yet)
I am facing the following issues
Whether I select Arduino Mega or ESP 32, I am getting the same following error "Compilation error: 'PxMatrix' does not name a type"
I am attaching the RGB_SCROLLING_DISPLAY_P10.ino and error codes generated when Arduino Mega was selected as the board and When ESP32 was selected as a board.
I have installed this library on 2 laptops, but I am seeing the same issue
I have also tried doing a clean installation of Arduino IDE and I made sure to clean up existing directories in DOCUMENTS
arduino mega error.txt
ESP32 error.txt
folder, but still could not resolve it.

Kindly guide me, on what steps I need to take to correct this error.

RGB_SCROLLING_DISPLAY_P10.zip

Hi, I'm working through some issues of my own with PxMatrix and my ESP32 at the moment but a quick look at your issue, I think PxMatrix display(32, 16, P_LAT, P_A, P_B, P_C, P_OE, P_CLK, P_R1, P_G1, P_B1);

should be

PxMATRIX display(32, 16, P_LAT, P_A, P_B, P_C, P_OE, P_CLK, P_R1, P_G1, P_B1);
(Note the capitalisation of MATRIX)
Also, in your PxMatrix.h file within the PxMatrix library folder, I had to add:
#include "hal/gpio_ll.h" ;

This got rid of the errors I was encountering although I am now working through other issues, such as my display only showing red and the bottom half not displaying unless I use display.fillScreen(255,0,0);

Fingers crossed this Github gets a bit more active and some of these issues are fixed to save the headscratching
