TWIS Slave and TWI Master mode drivers Example

[Anatomy_Park]

I am working through the TWIS Slave and TWI Master mode drivers Example using SDK 12 with the nRF52832 PCA10040 board and having issues. I am using Minicom through the terminal on a Mac to talk to the board. After setting up Minicom and loading the image to the board, I get the initial Welcome Message without issue, but that's the last of my success. Once I start entering commands, I receive an APP:WARNING:Communication error. I've attached a screenshot showing the error after using each command. I'm not really sure what to check for as the error differs from what the example document tells me I should get. Any help would be appreciated.

Did you short the correct pins, as described in the example documentation?

TWI_SCL_M - EEPROM_SIM_SCL_S
TWI_SDA_M - EEPROM_SIM_SDA_S

The defaults for the example in SDK 12.2.0 for PCA10040 is:

#define TWI_SCL_M                3   //!< Master SCL pin
#define TWI_SDA_M                4   //!< Master SDA pin
#define EEPROM_SIM_SCL_S         31   //!< Slave SCL pin
#define EEPROM_SIM_SDA_S         30   //!< Slave SDA pin

I did, but appears I did it incorrectly. Thank you for making me verify that. Apparently P0.2 is not Pin 3 and so on because I thought P0.0 was Pin 1. Oh well. It's working now. Thank you.

The pin numbers used in the code corresponds to the GPIO pin number (P0.00 = 0, P0.01 = 1, etc.).
