T4-S3 (H678) SD-card pins reuse? #62

Closed pike2k closed 1 month ago

pike2k commented 1 month ago

There's not many free GPIO's on this board, so I wonder if GPIO 01, 02, 03, 04 which are all connected to the onboard SD-card reader can be reused?

It seems like this file sd_diskio.cpp tries to init the SD-card. I don't want this SD functionality, can it be disabled somewhere?

After amoled.begin(), call SPI.end() to end SPI binding

Thanks Lewis, I tried adding SPI.end(); after amoled.begin(); in setup() . However, It did not stop the SD init:

I updated the initialization method of T4-S3. Please use beginAMOLED_241(false) to initialize instead of begin(). This way you can freely control whether sd should be initialized.

bool disable_sd = true;
bool disable_charge_led = true;
amoled.beginAMOLED_241(disable_sd,disable_charge_led);

Thanks Lewis. I will test it as soon as I figure out how I can use the master of Lilygo-AMOLED-Series in PlatformIO instead of 1.08 that I was using previously!

pike2k commented 1 month ago

Lewis, I have not been able to figure out how to use Master version of this library with PlatformIO. I believe it goes against basic principles how you are supposed to use PlatformIO? Is there any chance that you could release 1.0.9?

lewisxhe commented 1 month ago

Did you not figure out how to use platfromio? Did you read the README?

1.0.9 will not be released, I will release 1.1.0. I will stop for a few days to see if there are other problems. If there are no other problems, I will push V1.1.0 to arduino library today.

I did a quick test with one of the involved SD IO's and it was free, so closing unless something pops up :)
