Hello team,
when i flash the LCD driverlib sample code from MSP430FR5xx_6xx_DriverLib_Users_Guide-2_91_13_01.pdf(page 251) document, it's not working, however when execute the LCD register based code from TI Examples , its working fine. need help to resolve it on EVMmsp430fr6047 board.
not working code
MSP430FR5xx_6xx_DriverLib_Users_Guide-2_91_13_01.pdf , refer page 251. it has few wrong macros, i have corrected it, still its not working.
working code
