grblHAL driver for MSP432P401R (MSP-EXPMSP432P401R LaunchPad)
License: Other
I use MSP432P401R to run grblhal. I want to ask how MSP432P401R connects to the keyboard, or how MSP432P401R connects to the "GRBL_MPG_DRO_BoosterPack" project. I can't find the relevant instructions.
At present, I only connect the serial port of the "GRBL_MPG_DRO_BoosterPack" project to MSP432P401R, and my keyboard is now connected to the "GRBL_MPG_DRO_BoosterPack" project.
I see that the "GRBL_MPG_DRO_BoosterPack" project has a second I2C interface to relay keyboard data. I have connected this I2C interface with MSP432P401R, Press the button, nothing happens.
I see the following lines of code in the driver. c file of MSP432P401R:
#if I2C_STROBE_ENABLE
case PinGroup_Keypad:
if(i2c_strobe.callback)
{
i2c_strobe.callback(0, !BITBAND_PERI(I2C_STROBE_PORT->IN, I2C_STROBE_PIN));
}
break;
#endif
I2C_STROBE_PIN
Where should be connected? Does this pin tell MSP432P401R that the key is pressed now ?
If my "GRBL_MPG_DRO_BoosterPack" project is now in MPG mode, will the keyboard function be turned off ?
Can you give me some help? Thank you very much.
