Description
When compiling the linux example for raspberry pi4 I get an compiler error that the function evdev_read is returning a bool instead of a void.
I checked the lv_hal_indev.h and here it is defined as a void. However in v7.11 of lvlg this was defined as a bool. This is change an error because the device driver endev.h defines the function evdev_read as a bool
What MCU/Processor/Board and compiler are you using?
Raspberry py 4
What do you want to achieve?
Compile lv_port_linux_frame_buffer example inclusive touch support
What have you tried so far?
Check difference between version 7 and 8
Code to reproduce
Add the relevant code snippets here.
The code block(s) should be between ```c and ``` tags:
/*You code here*/
// Initialize and register a pointer device driver
lv_indev_drv_t indev_drv;
lv_indev_drv_init(&indev_drv);
indev_drv.type = LV_INDEV_TYPE_POINTER;
indev_drv.read_cb = evdev_read; // defined in lv_drivers/indev/evdev.h
lv_indev_drv_register(&indev_drv);
evdev.h
/**
* Get the current position and state of the evdev
* @param data store the evdev data here
* @return false: because the points are not buffered, so no more data to be read
*/
bool evdev_read(lv_indev_drv_t * drv, lv_indev_data_t * data);
## Screenshot and/or video
If possible, add screenshots and/or videos about the current state.
