Hello
I am designing a knitting machine which requires to change the knit design after some regular period. The user will design and feed the data serially through computer to 8051. Where and how should I save this data such that it can be changed after some time.
Thanking you
And how large are these downloaded patterns? Could you store them in EEPROM? Have you considered some of the more recent ARM Cortex-M0/3/4 type parts? More memory, faster, USB, ...
Along with WP's questions, I must ask have you looked at the 'Traffic' example program in the RxTiny2 example folder?
There is code for a serial circular buffer that will give you some guidance for your serial data stream.
The code in the 'Measurement' example will show you methods for searching/clearing unwanted data such as delimiters, blanks, etc.
