Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: TXS0108E, CC1310, PCF8574

Tool/software: Code Composer Studio

CC1310 communicates with display HD44780 via I2C. Interfacing hw: PCF8574 and TXS0108E. TexDispI2C6 is 4 bits interface. TexDispI2C8intf1 is 8 bits interface. The only difference between them is:

void LcdInit(void). The latter works better regarding power switch on.

Hi Trevisan,

I'm not sure what the question is.

Thanks,

Alexis

I take the chance to ask you 2 questions:

1) Inside e2e screen environment, where is a button to start a new thread or to simply post an article, without asking anything?

2) About my present article: sometimes, when I switch on the power, CC1310 communicates correctly with HD44780, but nothing is displayed, apart the 2 rows

blank. I think it's a problem with HD44780 initialization.

Thanks

Hi Trevisan,

1. I suppose you are welcome to share without asking a question, but the method of posting is the same.

2. I think you may find this useful: https://e2e.ti.com/support/archive/launchyourdesign/m/msp430microcontrollerprojects/666684
