MSP430 Ultra-Low Power 16-bit Microcontroller Forum
The low contrast of LCD interfaced to msp430 f4783
Hi all ,
I am using the CPU msp430f4783 having inbuilt LCDA controller,
The LCD which i am using is 4-Mux, 1/2 bias ,and is having VLCD =3.3V.
The board consist of LFXT1 crystal of 32KHz sources the ACLK.
The LCDA controller register configuration is as follows
LCDACTL = LCDFREQ_32|LCDON|LCDSON|LCD4MUX; // 4mux LCD, ACLK/32
LCDAVCTL0 = LCD2B;
LCDAVCTL1 = 0; LCDAPCTL0 = LCDS0+LCDS16 + LCDS12 + LCDS8 + LCDS4; // Segments 0-19 +//|LCDREXT
Also i tried with enabling external bias resistors ,but found no change in the contrast.
I tried with 1/3 bias also ,but the status of LCD was the same.
All the time the LCD segments displayed are not clear in the normal view ,
The Viewing angle of LCD is specified as 6'o clock.
Please let me know if some where i am going wrong or any other points which i need to take care
Thanks in advance
