Pins that are pulled up or down during RESET can be used as inputs if during RESET your circuitry does not drive them or if it drives them to the required state for boot.  They can all be used as outputs after RESET.  P2_7 should be driven low during RESET to enter ISP mode which is used for loading C programs, in that case the other BOOT select pins are ignorred. Some of these digital pins are also connected to the Arduino digital pins. In most NXP parts the port designation corresponds to the GPIO port, this is **NOT** the case with the LPC4330.  See the NXP user manual for detailed pin assignments. **Analog connections and Arduino pin connections**  ![](/images/typhoonH2.jpg) **AD pins** With the DATAlogger, the AD converters are connected to 8 dedicated analog pins.  ADC0 can be used as an analog input, or the output of the DAC.

Alternate Pin functions

The LPC4330 supports a number of dedicated functions.  Those include 4 UARTs, USB, 2 SSPs, 1 SPI, 2 CAN, 2 I2C, I2S, 2 multi-channel PWMs, Quadrature Encoder, dedicated motor control PWM, interrupts, timer counter capture and match.

In addition most can be configured with pull-ups and default to pull-ups following reset.

Details can be found in NXP's User manual.

UARTs are enabled by calling BAUD(x) for x=0 to 3.  UART0 is enabled by default as the programming debug connection.  The pin assignment BASIC uses is in the following table (you can change the settings by changing the PINSEL registers, details in the NXP User Manual)

Power connections

Diode steering allows 5V power to be supplied from either the USB connector or the 6 pin Serial Debug connector.

If you intend to supply 5V power from the Arduino 6 pin power connector, you should not connect the USB connector.

The schematic describes this circuit

The full schematic can be seen here

Real Time Clock Oscillator

The DATAlogger has a provision to load a 32 KHz crystal (Y2) and 2 20pf caps (C9 and C10) to use that for the Real Time Clock.  It can also add battery backup by loading the ML2020 battery (on either top or bottom of board), 330 ohm resistor (R5) and a BAT54C diode (D3).

The crystal should be a 32.768 KHz can type with an 18pF rating the capacitors are 0603 size 20pF.

To startup a user BASIC program when a battery is installed add this code to the start of your code

#include "LPC43xx.bas"

main:

    RTC_REGFILE(63) = 0            ' you can also use other values to indicate other features to control your program.

The firmware writes either &H41BEAAAA or &HBE415555 which if found on startup inhibits the user program from starting on power up.
