# ESP32_DmaSamples
This is an image drawing sample using DMA transfer of SPI master driver.
## Description
The ESP32 SPI master driver has a DMA (Direct Memory Access) transfer function that allows the SPI master driver to directly send and receive data in the memory without a CPU.
With this function, the CPU can do other work during SPI data transfer.
## Requirement
* https://github.com/tobozo/M5Stack-SD-Updater/ (For M5Stack)
* https://github.com/Bodmer/TFT_eSPI/ (Other than M5Stack / M5StickC)
