V1.5.0 for L011 and L021 miss following defines:
#define DMA1_Channel6 ((DMA_Channel_TypeDef *) DMA1_Channel6_BASE) #define DMA1_Channel7 ((DMA_Channel_TypeDef *) DMA1_Channel7_BASE) RM0377 Rev5 tells that DMA1 for Cat 1 devices is full featured, so this contradicts ''full-featured''. Dataseeht also tells about 7-channel DMA controller. Please correct this inconsistancy2016-03-22 06:22 AM
Hi bonnes.uwe,
•In the RM0377 (Rev5), section 10: Direct memory access controller (DMA): “The DMA controller has up to 7 channels (except for category 1 devices which feature up to 5 channels)�•In the STM32L011x3/4 and STM32L021x4 datasheets, paragraph 3.9 Direct memory access (DMA):� The flexible 5-channel, general-purpose DMA is able to manage memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers.� But I confirm that there is a typo in the first page of datasheets and it will be corrected later.-Syrine-
