4d systems 4d arduino adaptor shield C hardware revision 2.xx ? 201 4 4d systems page 4 of 8 www.4dsystems.com.au 4d arduino adaptor shield 2. configuration options on the 4d arduino adaptor, four jumpers (j1, j2, j3 and j4) have been added to provide flexibility to the users arduino project, to enable i/o to be changed or disabled as required, including the power source for the display. header 1 (h1) header 1 (h1) is used to connect the 4d arduino adaptor shield to the 4d systems display module of choice, using the 5 way cable supplied with the shield. this cable provides 5v, gnd, tx, rx and reset signals to/from the display and arduino, allowing them to communicate. header 2 (h2) a 4d programming cable/adaptor connector ( h2 ) has been added which can be used to power the display module in the case the display being used requires more power than can be provided by the arduino (for example if the arduino is powered off a laptop usb ra ther than a 5v jack). if the 4d programming cable/adaptor isnt used and an external power supply is, then the res pin can be used to reset the display externally, if required. see j1 below. the power supply source is determined by the j2 jumper, please re fer below. note: the rx and tx signals from the 4d programming cable/adaptor are not passed from this header, it is used to provide additional power only. arduino reset button (t1) t1 is a reset button for t he arduino, not for the display. this allows access to the arduinos reset button which m ay be covered up when a shield in placed on top of the arduino for a number of the arduino models. j1 j2 j3 j4 h2 h1
4d systems 4d arduino adaptor shield C hardware revision 2.xx ? 201 4 4d systems page 5 of 8 www.4dsystems.com.au 4d arduino adaptor shield jumper 1 (j1) j1 enables the display reset to be changed from being triggered from the arduino on gpio d4 when in the ar position, or from the h2 connector by means of an external source, when in the pr position . if the jumper is connected between the ar pin and the centr al res pin, then the display can be reset by setting d4 low in the arduino logic, and then high again. if the jumper is connected between the pr pin and the central res pin, then the display reset is controlled via the h2 connector . this could be switched low by an external circuit, providing an external method of resetting the display. removing the jumper from j1 entirely will disconnect the displays reset from the arduino completely, which may be valid for some projects. note: d4 is always pulled low to gnd via a 4.7k resistor due to the nature of the reset circuit. so even if the j1 is disconnected, the arduino d4 input is always going to have a 4.7k pull down on it. in most cases this should not affect operation of d4 if it is to be used for something else in a project when j1 is disconnected, however it should be noted that this is the case when using this shield. jumper 2 (j2) j2 enables the power source for the display to be changed from being powered via the arduinos 5v supply, or via the h2 conne ctor. if the arduino is powered from the u sers computers usb, some computers cannot provide enough current for both the arduino and the display to be powered off the same usb port, so auxiliary power can be required. if j2 is connected between the ar pin and the central pwr pin, then the display is powered off the arduinos 5v supply. if j2 is connected between the pr pin and the central pwr pin, then the display is powered off the h2 connector, via something like the 4d programming cable. 5v could also co me from an external power source if desired. removing the jumper from j2 entirely will disconnect power from the display. jumper 3 (j3) j3 enables the serial signals from the display to be received either onto d0 or d2. d0 on most arduinos is the hardware serial port 0 rx pin . d2 is often used for software serial. this allows flexibility for different setups. if the jumper is connected between the d0 pin and the central rx pin, then the arduinos hardware serial port 0 will be connected to the display. in this configuration, programming of the arduino is not possible without disconnecting the display, as the usb programming signals for the arduino will also be received by the display, which will result is corrupt programming signals being re ceived if the display transmits anything , resulting in a failed programming attempt. disconnecting this jumper will disconnect the arduino from the display, allowing the arduino to be programmed . if the jumper is connected between the d2 pin and the centra l rx pin, this will allow software serial (or similar) to be used to communicate to the display. the arduino should be able to be programmed successfully when the jumper is in this position without having to remove the display from h1 due to the display an d arduino not sharing the same serial port as the arduinos usb programming . if desired, a jumper wire can be placed from the central pin of j3, to a completely different pin on the arduino, such as d19 on a n arduino mega, allowing hardware serial1 to be used. jumper wires are not included. jumper 4 (j4) j4 enables the serial signal to the display to be transmitted from either the arduinos d1 or d3 pins. d1 on most arduinos is the hardware serial port 0 tx pin. d3 is often used for software serial. please refer to the description for j3 above, the same applies for j4 . if the jumper is connected between the d1 pin and the central tx pin, then the arduinos hardware serial port 0 will be connected to the display. if the jumper is connected between the d3 pin and the central tx pin, will allow software serial to be used to communicate to the display. removing the jumper will disconnect the arduino from the display. if desired, a jumper wire can be placed from the central pin of j 4 , to a completely different pin on the arduino, such as d 1 8 on a n arduino mega, allowing hardware serial1 to be used. jumper wires are not included.
