ARM LPC2138/48 Mini Development Board – LCD Interfacing

ARM LPC2138/48 Mini Development Board comes interfaced with an LCD module (2×16). Based on the number of data lines (4 or 8) used, LCD can work either in 4 or 8 bit mode. Here, the circuit is designed to work in 4-bit mode. Contrast can be adjusted by using the on-board potentiometer connected to pin3 of LCD. Control lines (RS, R/W ,E) are respectively connected to port pins P1.17, P1.18, P1.19 and data lines (D4-D7) to port pins P1.20, P1.21, P1.22 & P1.23
