Zephyr on Hexiwear and integrated Display Support
|
Marvin Beckmann <marvin@...>
Hi guys,
I am using Zephyr on the Hexiwear Board. I accomplished to use the hearrate sensor and some other sensors on the board. But I am still having trouble with the integrated Display (SSD1351 OLED Display with SPI) I didn't find drivers for this display. So i decided to use the SSD1306 Drivers. It seems to work, because the functions for the display return zero, but display is not showing anything. Is there any chance to support SPI on the Hexiwear Board and using the integrated display. Here is the link for my code: https://gitlab.com/MarvB19/hexiwear_display <https://gitlab.com/MarvB19/hexiwear_display> I hope you can help me :) Have a nice day. Kind regards Marvin Beckmann |

Hi Marvin,

The Hexiwear board can use the same SPI driver as the FRDM-K64 board, but you need to configure the SPI pinmuxes. Check the schematic to determine which SPI instance and pins to use. They may not be the same as FRDM-K64F, but should look something like this: https://github.com/zephyrproject-rtos/zephyr/blob/a9b1c42f403737a2abfeae31e6b5fd43f1d7869f/boards/arm/frdm_k64f/pinmux.c#L61-L67 Maureen -----Original Message-----
