Hi,
I reduced my whole code to:
EVE_LIB_BeginCoProList();
EVE_CMD_DLSTART();
EVE_CLEAR_COLOR_RGB(0, 0, 0);
EVE_CLEAR(1, 1, 1);
EVE_COLOR_RGB(255, 255, 255);
EVE_BITMAP_SOURCE(uStartAddressLogo300x300);
EVE_CMD_SETBITMAP(uStartAddressLogo300x300, EVE_FORMAT_RGB565, 300, 300);
EVE_BEGIN(EVE_BEGIN_BITMAPS);
EVE_VERTEX2F(currentx * 16, currenty * 16);
EVE_END();
EVE_DISPLAY();
EVE_CMD_SWAP();
EVE_LIB_EndCoProList();
EVE_LIB_AwaitCoProEmpty();
And this I execute continuously.
And even this small display list gives problems.
I changed my code for HAL_WaitCmdFifoEmpty to
uint8_t HAL_WaitCmdFifoEmpty(void) {
uint32_t readCmdPointer;
uint8_t retry = 0;
// Wait until the two registers match
do {
// Read the graphics processor read pointer
readCmdPointer = HAL_MemRead32(EVE_REG_CMD_READ);
retry++;
} while ((writeCmdPointer != readCmdPointer) && (readCmdPointer != 0xFFF) && (retry < 250));
if (retry == 250) {
printf("retry HAL_WaitCmdFifoEmpty");
}
if (readCmdPointer == 0xFFF) {
// Return 0xFF if an error occurred
return 0xFF;
} else {
// Return 0 if pointers became equal successfully
return 0;
}
}
And I get now and then this retry HAL_WaitCmdFifoEmpty about 10-15 times every time it comes.
Also, when I let I ran al night, the display was frozen in the morning.
Something must be wrong in this library and I don't know what.
It causes the display to block/freeze. (a while loop that won't exit, like the one I already edited or it blocks)
Please help.
