Hi Community,

i have problem with my dual regular simultaneous adc when i use ltdc.

if i disable sdram, the adc ( dual regular simulataneous with dma ) works properly but the ltdc fails.

Probably not, but internal SRAM is significantly more finite in size.

Check errata for known issues.

i couldn't start adc ( dma ) simultaneously with ltdc using cube mx.
