// If the VSPI port is in use and pins are not accessible (e.g. TTGO T-Beam) // then uncomment the following line: //#define USE_HSPI_PORT // Comment out the following #define if "SPI Transactions" do not need to be // supported. When commented out the code size will be sma...
SPI主机可以发起全双工/半双工的通信,全双工通信中,总传输数据长度由spi_device_interface_config_t::command_bits、spi_device_interface_config_t::address_bits、spi_transaction_t::length决定,spi_transaction_t::rxlength仅决定了缓存区接收数据的长度;但半双工通信中,读写不同步,总传输数据长度由只spi_transac...
