ok cool - small request - put the numpy import into |
This brings back the Numpy approach to converting pixel data for the SPI interface from the original Adafruit_Python_ILI9341 library. The use of Numpy instead of the previous double loop results in a performance boost of a factor >10 when testing on a Raspberry Pi Zero. When Numpy is not available at runtime, the previous double loop is used. Fixes #46

Ah sorry, didn't realize that was a requirement. I wasn't able to put the import inside of |

I should be able to test in the next couple of days after I get back. |
