Data segment for a classic 8051 is 128 Bytes & for an 8052 is 256 Bytes No. The Data segment is only ever 128 bytes; The additional "internal" (sic) RAM of the 8052 is Idata. I was able to increase the buffer size to 239 with:
idata unsigned char image_buffer[239]; Beware that the Stack requires idata... But what about my 508 Byte array? Seems I would have to use external RAM!? You would have to use Xdata - which may or may not be physically "external" to the chip... |

| "RAM" and "Data Memory" are not synonymous | Andy Neil | 07/03/09 05:48 |
