Hai all guys The ADSP-2181 EZ-kit lite have 80KB of internal RAM , and preferably gives better performance and stability for assembly code with host connected (No Hangups !). But i feel some problem when i go for C- coding as it produces code that is bulker code. So i want to connect external RAM for the same. Maximum of h

I want to process a huge(~0.5Mb) file stored on my PC hard disk with the EZ Kit Lite(2181).I suppose it is to be done in steps with chunks of data from disk being transferred to the DSP memory and vice versa during the course of program execution.I would like to know how to do this.

Hi! I have that EZ-LAB (the one on "subject") and recently downloaded the VisualDSP++ 2.0 for 21XX development environment, and also installed the 2181_EZ_KIT_TOOLS_2.00.0 software for using the EZ-LAB within VDSP++2.0.

Dear list, I'm working on a project with the ADSP-2181, where I have 8-bit RAM and ROM chips, and an LCD panel, on the bus. The memory chips and LCD are pretty slow, so I'm using 5 to 7 waitstates with them all. Meanwhile I have a time-critical ISR that is called 625 times per

hi all i'm using adsp2181 ezkit lite board. As we all know 2181 has only 1 timer. my requirement is to use this timer for 2 purposes using status condition. i'm using timer for UART and i need to use the same timer for generating some control pulses for my project. my idea is to use a status check. i.e. if dm(status)=1 then the timer is dedicated to UART and if dm(status)=0 the timer is...
