Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...
Microchip’s new 23K256 is a serially interfaced 32 kilobyte SRAM memory chip, available in 8 pin DIP and 8 pin SO packages. SRAM, like EEPROM, is a data storage medium. Data stored in SRAM is lost ...
The project provides the conversion between an RS232 serial interface and an SPI interface which uses the SSP port on a 16F819 device. It is possible to send any sequence of bytes on the SPI interface ...
