I'm just getting started with my Stellaris LP, and am porting my msp430 library for my ILI9341 based display over to the Stellaris. I got it working, but am encountering performance issues. I'm using Energia 12. The ILI9341 is very demanding on the SPI bus. To test the performance I created a simple benchmark that involved filling the display a couple of times. On the MSP430, I was able to get good performance by putting SPI.setClockDivider(1) after SPI.begin(). With this setting, the MSP430F5529 at 25MHz was able to complete my benchmark in 1608mS. Then I ported it to the Stellaris
