Using simple digitalWrite() calls, I'm able to write to the LCD, but I'm trying to switch to using the Energia SPI library. The documentation for SPI.begin() says I can set a slave select pin; however, the compiler rejects a call to SPI.begin(LCD_CS) because there is no SPI.begin(int slaveSelectPin) defined. With the following code, the default pin 2 slave select appears to be used, because it happens to be connected to the buzzer on the ADS1118 Booster Pack, an

Do the Booster Pack design guidelines include any bottom-side exclusion areas for downward-extending pins?
