Serial Communication in SHARC - Author Unknown - Sep 6 13:44:00 1999
|
Hai, SHARC doesn't provide an interrupt when one DMAs data for serial transmission. I've tried out some of the asm codes provided in the manual, but it doesn't seem to work out. The only asm code that seems to work is that of the loopback configuration and that too only in the simulator. Could you please inform me how to transfer data in the SHARC's internal memory to say a CRO that has been connected to the serial port of SHARC (using asm code)? Manoj |

NOT TRUE. TRY READING THE SHARC MANUAL. SPECIFICALLY PAGES 10-10 and 10-12 of the Users Manual. Setting STCTLX (transmit) bit 18 or Setting SRCTLX (receive) bit 18 to 1 would enable the DMA. Cheers.
