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...

hi everybody, I tried to establish sport comm between adsp2181 and BF533. could not succeed. I tested separately both 2181 and BF and are working fine. I tried using loopback mode ( DT connected to DR of same processor) and it worked but when it comes to interfacing its not working. what could have gone wrong? First of all are the 2 processors compatible ( i mean can i really establis...

Hi friends ADSP 2181 and BF533 are not compatible. ADSP2181 is a 5V logic(TTL) while BF533 is a 3.3V logic device. If i need to connect ADSP2181 sport to BF533 sport is it enough if i use a voltage divider for level shifting? If not which level shifter IC is ideal in this case? I need to level shift all 5 signals on ADSP2181 sport i.e DT,DR,TFS,RFS,SCK.
