8596d46bce since now we have SPI DMA for nrf, we need to add some more #define's 2019-10-17 15:05:39 -04:00

c4e7aea568 better use nrf spi with dma for drawing pixels with nrf52840 (#248) 
* better use nrf spi with dma

* only use spim dma API with 52840

0e92646066 Teensy T4.0 support (#232) 
The Teensy T4 (__IMXRT1062__) port registers need to be 32 bits unlike the Teensy 3.x which are 8 bits.

adafruit_ili9341  and adafruit_st7735 libraries graphic test

Removed compiler warning

that PROGMEM was previously defined.  So undefine it first...

Note: Thought of simply doing nothing here
(do neither the #undef nor the #define).

But that gives compiler error

Teensy T4 - Make Bit Bang version work.

With T4, the Port/Set registers are masks not single value.

So need to setup those class variables:

Also found that bitbang of T4, was too fast for display, so put in same slow
down that ESP32 has, which gets the clock down to mayby 12.5mhz

Tried these changes out with both:
adafruit_ili9341  and adafruit_st7735 libraries graphic test
