function Config¶

Config()

Public Attributes Documentation¶

variable periph¶

UartHandler::Config::Peripheral periph;

variable rx¶

dsy_gpio_pin rx;

variable tx¶

dsy_gpio_pin tx;

variable rx_buffer¶

uint8_t * 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.

variable rx_buffer_size¶

size_t 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.
