Member Data Documentation

periph

UartHandler::Config::Peripheral daisy::MidiUartTransport::Config::periph

rx

dsy_gpio_pin daisy::MidiUartTransport::Config::rx

rx_buffer

uint8_t* daisy::MidiUartTransport::Config::rx_buffer

Pointer to buffer for DMA UART rx byte transfer in background.

By default this uses a shared buffer in DMA_BUFFER_MEM_SECTION, which can only be utilized for a single UART peripheral. To use MIDI with multiple UART peripherals, you must provide your own buffer, allocated to a DMA-capable memory section.

rx_buffer_size

size_t daisy::MidiUartTransport::Config::rx_buffer_size

Size in bytes of rx_buffer.

This size determines the maximum Rx bytes readable by the UART in the background. By default it's set to the size of the default shared rx_buffer (256 bytes). While much smaller sizes can be used, data can get missed if the buffer is too small.

tx

dsy_gpio_pin daisy::MidiUartTransport::Config::tx
