Other Parts Discussed in Thread: TMS570LS1224, HALCOGEN

Hi Friends,

I want to know Which PIN is available for I2C communication on TMS570LS1224 Launchpad. Because here in the image I connected to launchpad to max6958 7-segment driver but I am not getting result .So if I done any mistake please let me know.

In this image A green wire which connected to launchpad represent SDA and yellow means SCL.

Regards,

Arvind.

Arvind,

The Hardware I2C module isn't located on the booster pack standard I2C location (long story) but if you are just jumpering wires you can get it where I marked below.

If you were building a booster pack and needed to use the standard I2C location then the HET pins are there and HET can emulate I2C with a custom program.

Hi Anthony,

I executed my I2C code but it is stuck at this line while ((i2c->STR & (uint32)I2C_TX_INT) == 0U) in i2c.c file. when i am sending second byte.

Arvind
