I don't have any free pins available, and GPIO6 to 11 are unused but datasheet recommend to NOT use them
Thanks
what we have:
you have: GPIO2, GPIO14, GPIO15 wired for touch LCD
you need to add SD card, and want to know, can you do this.
and you don't have any free pins available,
and GPIO6 to 11 are unused but datasheet recommend to NOT use them
cause we have not more infos, what you do with the pins ( SPI, I2C, other custom mode )
and what you not connect GPIO06 to 11 cause which datasheet ...
we look deeper here first moment:
- images.jpg (3.7 KiB) Viewed 3722 times
and we see not more infos like you give.
so perhabs would be nice, what you do want to do in detail
SPI mode
I2C mode
or custom mode
and what SD Card
MMC mode
SPI mode
1 bit mod
2 bit mod
4 bit mod
you see there are many thing possible
perhabs you tell which perípheral mode you want use for
- LCD Touch
- SD Card
and how you connected touch pins -
this can be very be important cause interupting..
and we can help detailed further
thanks for understand
best wishes
