GPIO on i.MX RT1010 EVK

[danielmilutinov]

Hello, 

I have found the following GPIO connections on the i.MX RT1010 EVK Arduino Interface:

Pin	Pin name	GPIO	Arduino Interface Connector
59	GPIO_AD_01	GPIO1_15	J56_14
58	GPIO_AD_02	GPIO1_16	J56_16
57	GPIO_AD_03	GPIO1_17	J57_10
56	GPIO_AD_04	GPIO1_18	J57_08
55	GPIO_AD_05	GPIO1_19	J57_06
52	GPIO_AD_06	GPIO1_20	J57_12
51	GPIO_AD_07	GPIO1_21	J26_02
48	GPIO_AD_09	GPIO1_23	J26_04
47	GPIO_AD_10	GPIO1_24	J26_06
43	GPIO_AD_14	GPIO1_28	J26_08
12	GPIO_01	GPIO1_01	J57_18
11	GPIO_02	GPIO1_02	J57_20
3	GPIO_09	GPIO1_09	J56_02
2	GPIO_10	GPIO1_10	J56_04
74	GPIO_SD_02	GPIO2_02	J57_02

There is also a GPIO1_11 connection at J54_02 (thank you to John Adriaan for making me aware of this), so there appear to be a total of only 16 GPIO connections available when using a 0.1” cable, which I find a little surprising considering the i.MX RT1010 has 44 GPIO pins and the Arduino Interface has 64 connectors.

For my hobby calculator project I used an Arduino to scan the keypad and send the number of the key pressed to the i.MX RT1010, as 11 pins are used by the display (parallel interface) leaving only 5 pins for the 6 column, 8 row matrix keypad (which needs 14). I’ll provide further details if anyone is interested:

Hi Daniel,

Thanks for the pinout details, very useful. I'm trying to connect an LCD display to my RT1010, can you share your code and schematics? I have no idea how to make the display work.

Thanks in advance.

Hello Raul, 

I used this display from Adafruit (parallel interface, SPI is also available), and had to port the provided Arduino code to the RT1010. Connecting a display can be challenging, as there are different display controllers. Which display are you using?

Hi Daniel,

I have this display at hand. Apparently their driver chip is from the same vendor as yours. The parallel interface could be the same, I'll check it as soon as I can.

Thanks!
