sorry about such a basic question, but I can't get the LPCOpen I2C example to run out of the box.
It compiles and runs fine, but *nothing* happens on the I2C bus. (I have an oscilloscope hooked up to the I2C lines)
- MCUXpresso IDE v10.3.1 [Build 2233] [2019-02-20]
- "periph_i2cm_interrupt" example from "lpcopen_2_19_lpcxpresso_nxp_lpcxpresso_812.zip" (came with IDE)
- LPCXpresso LPC812 REV A board
I also tried the other I2C examples (i2cm_polling, i2cm_rom), but the result is the same. Neither I2C line will ever see any signal change.
I must be missing some super basic setting. Any ideas?
