STM32F722 +LCD160CR v1.1, WBUS pins
Posted: Wed Aug 14, 2019 9:52 pm
Dear users,
I am arduino user (hobbyist), but I use&like python so I would like to try micropython. I bought pyboard-D STM32F722 + LCD160CR v1.1.
How could I connect my uPC with LCD? I thought following:
1) STM32F722 - has 2x WBUS
2) LCD160CR v1.1 - has 2x WBUS
3) I soldered headers at X and Y pins LCD160CR board
So I connected both WBUS pairs, it match together . And when I test headers at LCD160CR board, X - pins works, but Y not. I would like to use X pins for LCD, and Y for pressure/temperature sensors.
Please, is somewhere schematic for LCD160CR v1.1, with W-BUS? (everywhere is only version 1.0, without W-BUS). Probably I don't understand it, by my multi-meter shows short circuit between X1-Y1, X2-Y2 at LCD board... Is it correct? (when you look at v10 version, there is also short circuit, right?).
Sorry for really silly question, but it is possible to use WBUS to "transfer" both X and Y pins from uPC -> LCD board?
Thanks, BR, ii
