Support for the UC1638 controller
|
|
|
|
20 Jun 2021:
|
|
The u8x8_d_uc1638_192x96 is tested and works.
|
|
The u8x8_d_uc1638_160x128 will probably not work, there is no display to test this
|
|
WARNING; The u8x8_d_uc1638_160x128 also has an inverted CS signal !!!
|
|
Changed the SPI mode from 3 to 0, because it work nicely with mode 0
