GHI Electronics,LLC Embedded Master User Manual

Custom Native Drivers

one support by Embedded Master but it uses a different initialization settings. Or slower

clock rate. The developer can use the GHI library to access the processor registers and re-

initialize the display with correct settings and even change the SPI clock rate. This is also

valid for TFT displays where a developer may need to change the timing characteristics of

the TFT signals.
