Abstract
In the previous chapter, software was developed to drive the OLED using master-mode SPI transactions. The STM32 platform does, however, support a DMA (direct memory access) Organic light-emitting diode (OLED) controller, which can be exploited to perform the I/O operations and leave more cycles available for the CPU. This chapter will explore how to set up and use that DMA controller to drive the OLED device.
