The same code is working on P89C52X2 & P89V52X2 but it is not working on 89V51Rx2,
Please find link for my sample program http://rapidshare.com/files/132070834/LED.zip I said:
Write some very simple, rudimentary program such as blinking a LED... If I say, SIMPLE, I mean it SIMPLE. There is a reason to keep things as simple as possible when you are trying something new - you don't want to be overwhelmed by the many new things of which quite a lot can go wrong - at the same time. That your code worked on a different microcontroller is IRRELEVANT. You are dealing with the differences, and once there might be many, you need to stick to what is expected to be the same. Look for example at http://www.8052.com/faqs.phtml?FAQ=120313 for something really SIMPLE. I also said:
Just an example: the 'V51RD2 has an "internal-external" RAM which is enabled by default, so all MOVX below 0x2FF will go from/to that memory rather than any attached external memory or other memory-mapped device. Sandeep somewhere deep in the code said:
#define xbyte ((unsigned char volatile xdata*)0) #define ANODE_LATCH xbyte[0X0000] Confront. JW |
