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 ...
Seven-segment displays are needed in many instrument designs. In conventional microcontroller-based designs, four output port lines are allocated for one seven-segment display. Figure 1 shows the ...
East Kilbride, Scotland Two dominant driving forces for the development of 8- and 16-bit microcontrollers are memory size and cost–purchasers are demanding more memory for less cost. Generally, ...
