Assembly
1) LCD Displays
I found ribbon cable is a nice way to organize the wires to the displays. There are two versions of the display and each must be wired differently. The original project used HW REV. 1.01. For that version, you'll need 12 conductors and I connected them in the following order:
1 | LED+ |
2 | LED- |
3 | RST |
4 | SDI |
5 | WR/SCLK |
6 | CS |
7 | X+ |
8 | X- |
9 | Y+ |
10 | Y- |
11 | VDD |
12 | GND |
If, instead, you have HW REV 2.0, you will need 13 conductors with the following order:
1 | LED+ |
2 | LED- |
3 | RST |
4 | SDI |
5 | RS (SCLK) |
6 | WR (DC) |
7 | CS |
8 | X+ |
9 | X- |
10 | Y+ |
11 | Y- |
12 | VDD |
13 | GND |
First I connected all the GND connections (2 GND & IM0, IM1, IM3 for REV1.01 or 2 GND, RD, & IM0 for REV2.00). Do not connect the bottom GND until you have the ribbon cable connected. After making all the ribbon cable connections (connecting the GND of the ribbon cable to the bottom GND pad), solder the GND bar from the previous step to the back of the bottom GND connection. Finally, make a connection from the back side 3.3V pin to IM2 for REV1.01 or to IM1,IM2,&IM3 for REV2.00. Take a break and repeat for the second display.
Examples of REV1.01 boards:
Examples of REV2.00:
Once the two displays are complete combine all wires except CS0, CS1, X+, X-, Y+, and Y-. Connect X- of the left display to X+ of the right. Similarly connect Y- of the left display to Y+ of the right. Insulate any exposed wires.
2) PCB
Refer to the schematics to place all the components on the board. If you plan to install into the CANary 3D enclosure, DO NOT install the battery holder or the socket for the mbed and, instead, connect two wires to the VB and GND pads nearby. You will have to install the battery holder against the back wall to avoid interfering with the right-hand display and the mbed will have to be directly soldered. I have not found a socket with a low enough profile to fit in the space provided (depth of enclosure is limited by the space behind the center console). Also, I recommend keeping as much lead as possible on the Zener diode (bending it as shown to clear the back wall). Although it is operating well within parameters, the Zener gets quite hot during extended operation and the leads help dissipate the heat and keep it away from the PCB and other components.Update: Several Zeners have failed resulting in damage to some users boards so I recommend using a DC-DC converter instead to bring the 12V down to 7V.
Once the PCB is populated, solder the LCDs to the PCB. CS0 connects to the right display and CS1 connects to the left.
Update: The Zener diodes tended to fail after a few months so I am recommending removing them and replacing with a DC-DC converter. This will run cooler and waste less energy, too. To install, remove the left display panel to gain access to the Zener. From there, the Zener can be removed and it's pads used to connect to the DC-DC converter. I recommend setting the output voltage on the bench before installing since the trim pot is tricky to reach once installed. Set it to 7V. The input can be connected to the left pad previously occupied by the zener and the output can connect to the right. GND(-) can be connected to the bottom right pad on the 2x6 header below the flex cable connector. Make sure the GND wire lies flat so it doesn't interfere with the connection of the flex cable.
Once soldered in place, the DC-DC converter can easily be mounted to the back wall with double sided tape above the battery holder.
3) Testing
1) | First step is to buzz out all connections from the LCDs to the pins in the main board |
2) | Next check the touch screen connections. On the main board, place an Ohm meter across X+ and X-. You should read 700 Ohms. Repeat for Y+ and Y-. Then test the resistance from X+ to Y+. With nothing touching the screens, it should read >100K Ohms and <1K when touching either screen. |
3) | When all connections are checked, solder in the mbed. Download and install the touch2 program http://mbed.org/users/TickTock/code/touch2/ to test the basic operation of the mbed and touch screens. |
tips: | |
Touch screen is sensitive - excess flux on X+,X-,Y+,Y- connection on mbed can result in flakey operation | |
If touch is not working, double-check the LCD0_CS and LCD1_CS are not swapped. LCD0_CS must connect to the CS of the LCD that has X- & Y- connected to the mbed. LCD1_CS must connect to the CS of the LCD that has X+ & Y+ connected to the mbed. | |
4) | Once touch2 works, it is time to connect to the OBD connector. I highly recommend double checking all connections from the OBD to the PCB with the cable in place before connecting to the Leaf. Buzz out all the pins in the OBS to make sure none are shorting to each other, Check that the 12V goes to the Zener (and nothing else) and the switched 12V to the resistor divider (and nothing else). Test the ground connection properly connects to ground and nothing else. |
5) | Once you are confident there are no shorts or wrong connections from the OBD connector, take a deep breath and plug it into your leaf. Touch2 program should come up and function. Unplug and install the latest CANary firmware. If you have the REV2.00 LCD boards, you will need to edit the precompile.h file in the TOUCH_TFTx2_w9341 library and set USE_ILI9341 to 1. Test all features before installing into the enclosure (gids, cellpair, menu system, logging) since installing and removing from the enclosure is a PITA. |
4) Enclosure
The 3D printer leaves a lot of powder behind - I used a strong spray of water to get it out of all the cracks. The enclosure comes with a rather rough finish. I recommend convincing yourself you like it, then simply lightly sand then paint before assembly. Sanding is very difficult - the nylon is very nicely fused and doesn't want to sand. I tried sandblasting and that didn't work either. I had some limited success with filler and then sanding, but only on the outside - it is too difficult to sand the face.
5) Final Assembly
Make sure you are well rested with lots of patience before attempting assembly. It is a puzzle figuring out how to get both displays and the PCB in place. Enclosure was too expensive for me to keep iterating to optimize for assembly. I ended up snipping the thin display posts shorter and using various tools to push the displays into place. Also, some USB connectors are taller than others. If you have one of the taller ones, you will have to deflect the back wall a bit while inserting the PCB (being careful not to bend the housing) to get it to it's opening in the back wall. Do use a screw in the provided post to secure the PCB as USB insertion will otherwise dislodge it.
I added an additional safety line which wraps around the center post to prevent the enclosure from becoming a projectile in the event of an accident. Installed:
