I am using the McBSP in mode SPI to read a external converter (ADS1271). It can then start the DMA transfer and allow the CPU to continue with other tasks. Use DMA with PWM Configure the timer so that an update event triggers a DMA transfer. In homogeneous media, N,N-Dimethylacrylamide (DMA) was grafted copolymerization to cellulose by a metal-catalyzed atom transfer radical polymerization (ATRP) process. So whether this limit can be increased? Also in XUDC driver of kernel XUDC_TRB_MAX_BUFFER_SIZE is 65536 and max packet size is 64 which limit maximum data transfer at a time as 65536*64 = 4MB So our requirement is to transfer 15MB atb a time. It could be a personally traumatic experience for you if you had to go back to school. For example, a PCI card can perform DMA by taking ownership of the bus and issuing the appropriate commands, which are preprocessed by the PCI bus controller and forwarded to the memory controller.
