Handling low-speed devices with high speed microcontroller
Started by 2 months ago●15 replies●latest reply 2 months ago●64 viewsCurrently I own a few AT89S52's and AT89LP52's and I run them with 22.1184Mhz crystals.The difference between the two is that the AT89LP52 processes code 10x faster,...
I'm trying to figure out the fastest way to convert a 16-bit number to 4 digits for an LCD display. I did adopt the use of the fast 16-bit division on another thread...
Arranging data packet between micros for optimal speed
Started by 2 months ago●5 replies●latest reply 2 months ago●47 viewsOk, I managed to get the microcontrollers (AT89LP52 and AT89S52) to execute code, but now I need a way to optimize my data flow.
I have one controller setup as...
