SPI TERMINAL is a SPI App, which allows you to control external devices using SPI. Your Flipper can act as a SPI Master or Slave device. The Slave mode allows you to sniff the communication between different SPI peripherals.
The App uses the Low-Level SPI Interface of the STM32WB55RG Microprocessor. All data is transmitted with DMA Sub-module and can reach speeds of up to 32 Mbit/s in Master and up to 24 Mbit/s in Slave mode.
It contains a rich Inbuilt Documentation.
