Intel co-founder Gordon Moore predicted in 1965 that the number of transistors per silicon chip would double every two years. This came to be known as Moore´s Law which has been proven accurate for the last fifty years. Many scientists argue that the law is soon to be broken because of physical limitations. The end […]

Interfacing PIC16F887 with FAT16 SD card After reading raw data (bytes and sectors) from SD card, now I’m going to use FAT16 file system to read and print text file located in 2 GB SD card. Read SD card raw data topic: MMC/SD Card raw data read with PIC16F887 microcontroller UART protocol is used to

This topic shows a simple interfacing of 2 GB micro SD card with PIC16F84A microcontroller. I used the PIC16F84A to read the SD card raw data which doesn’t require a microcontroller with high RAM or ROM. In this interfacing I used software SPI because the PIC16F84A doesn’t have a built-in hardware SPI module. In this

All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs)help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC can make
