Hi. I'm sure this has been covered but I have E100 mm+ and have purchased buydisplay eastrising ssd1963 5" display. I know the pinouts are not compatible but is there a pin to pin description/diagram to make it easier for me. thanks

The pinouts used by EastRising displays are an ongoing issue. I suspect that you are on your own here.

Hi antf70,

The good news is that those displays will work; however, you will have to 'map' the pins accordingly. The pin naming convention is identical apart from a couple of pins. Be patient whilst doing this and it will work first time.

My setup is currently in a box that I do not want to take apart just now - I have a demo later this week and don't want to mess things up at the last minute

I will see if I can find some paperwork notes to assist.

Thanks WhiteWizzard. I have wired the display and am getting a result except for some errant vertical lines. I did read in past posts I may need to load new firmware for this fix? (chip preloaded with V5.3 beta10).Also cannot get touch to work, should TCH IRQ on MM go to pin 37 on tft (TP BUSY_VDD)? Cant see 0 ohm jumper choice for backlight either. Will wait for your future posts, thankyou

If you can post a picture of your LCD connector (assuming it has the pins labelled) we might be able to help determine correct pin assignments.

Sorry, no pin labels on PCB but going by datasheet at https://www.buydisplay.com/download/manual/ER-TFTM050-4_Datasheet.pdf
Got backlight working fine, LCDPANEL CONSOLE looks good, just no touch response on GUI CALIBRATE and on power up get multiple Error: Touch not calibrated messages on screen.

Here is the mapping from the MM LCD connector to the EastRising LCD connector as far as I can work out.

This is just for the Touch panel signal wiring.

[code]MM Connector LCD Connector
Pin Function Pin Function
14 T_IRQ 38 TP PEN_VSS
13 T_DO 36 TP DOUT_YD
12 T_DIN 35 TP DIN_YU
11 T_CS 33 TP CS_XR
10 T_CLK 34 TP CLK_XL[/code]

Let us know how you go.Edited by Azure 2018-03-14

Thanks Azure. Have wired as per your post but still no response from touch, although not getting error messages on power up now. When I purchased LCD I chose the capacitive touch screen with in-built controller, figured this would be ok option? Will dig out logic probe to check mm+ getting T_IRQ signal. Still getting errant vertical lines on display also(am waiting for microbridge in post to load new firmware).

That wiring I posted is for the eastrising resistive touch screen.

I think the MM built in touch screen software is only for a resistive touch screen.

If I am wrong someone should chime in pretty quickly to correct me.

Unfortunately the Capacitive Touch option will not work - it has to be the Resistive type as Azure has already highlighted.

I am still looking for my paperwork regarding the 'adaptor' I had made for these EastRising TFTs.

Thanks for your responses guys. My bad.

That's what you get for going for the cheaper one and not getting the options right. Look forward to your posts WhiteWizzard.

antf70 said . . . My bad.

These are actually very nice TFTs and are of a consistent quality (unlike cheap ones from eBay sellers). The only issue is the pinout is the 'second standard' which unfortunately is not the 'standard' that was implemented on the MM PCBs.

I will get around to producing the adaptor board one day!
