stm32f103c8t6_cubemx_ili9341_lvgl's Issues

Problem when trying to enable DMA

Hello. Thank you for sharing your code.
All is running fine, but when I try to enable DMA (in lvgl_init_f103.c):
#define USE_DMA 1
#define USE_DMA_IRQ 0

I get errors:
error: 'LCD_BASE1' undeclared

I tried with (found somewhere for ili9341):
#define LCD_BASE0 ((uint32_t)0x60000000)
#define LCD_BASE1 ((uint32_t)0x60080000)

But then I get the error:
undefined reference to `hdma_memtomem_dma2_stream0'

Did you were able to enable DMA?
Thanks!
