Solar Calculator

  What is efficiency ? Fill factor ? These things are measurement of solar panels how good they are. This is my javascript based solar calculator. It can calculate the fill factor of a solar panel for the given values.  I have created this calculator to try out flash. If there are mistakes in t

Interfacing CMOS static parallel RAM with a PIC

Interfacing CMOS static parallel RAM with a PIC

This circuit is to increase the RAM memory of a PIC microcontroller using a parallel RAM. The address of the data byte can be accessed or assigned by serial in parallel out shift registers. From this the number of I/O pins from the PIC can be minimized.

External Parallel SRAM with PIC microcontroller for beginners

External Parallel SRAM with PIC microcontroller for beginners

There are instances where we can not use SPI flash memory or non-volatile memory module since they are very slow in writing and reading and they can only operate write cycles to a limited number. This post is to introduce about interfacing a SRAM to a PIC microcontroller and communicating with it.
