Hello, I would like to use the interrupt driven serial I/O. see http://www.keil.com/download/docs/intsio2.zip.asp but if I use this code I receive following msg: Code:
EA=1; /* Enable Interrupts */
error C67: 'EA': undefined identifier
"I would like to use the interrupt driven serial I/O. see http://www.keil.com/download/docs/intsio2.zip.asp" That very page that you cited clearly states, "This example works with any 8051-compatible device" (my empahasis) If you want to adapt it to a non-8051 device (eg, a C16x or ST10), you will obviously have to change all references to 8051-specific features - such as bit names like EA!
There are two main elements to the INTSIO examples: 1. Handling the UART hardware & interrupts; 2. Handling the circular buffers. Obviously, the handling of the UART hardware & interrupts is specific to the 8051 UART and cannot be used on the C16x. You will need to re-write this part for your particular processor and/or UART - see your Data Sheet. However, the handling of the circular buffers is perfectly generic 'C' - so you can use this bit on other processors and/or other UARTs. In fact, I have done exactly that to drive "external" UARTs implemented in the programmable logic of Triscend E5 (RIP) devices.
There seems to be some confusion here. EA is the 'Enable All interrupts' bit on 8051. It has notthing to do with the EA I/O pin of the C166. For 166 we provide interrrupt driven serial I/O in the Keil\C166\Examples\Traffic folder. There is another interrupt driver I/O routine in the Getting Started User's Guide (GS166.PDF), Using On-Chip Peripherals, Serial Interface. It looks like these days users expect examples for all kind of peripherals in all kind of processors. Keep in mind that we are supporting 700+ devices which would required about 5.000 example projects.
