So I'm trying to use module_multi_uart along with app_sk_muart_com_demo.
I don't have a UART slice card (which provides an external 1.8432 MHz clock for the transmitter), so I'm using the internal clock by calling run_multi_uart_rxtx_int_clk(...).
I should be getting 11520 baud transmitted from the XMOS board. With a scope, I measure a 680us bit length, corresponding to about ~1470.6 baud.
I've tried playing around with some #define values in multi_uart_tx_conf.h but mostly it has no effect.
Is the code broken for cases where the internal clock is used, or am I missing something?
Thanks

Hi TSC, to use the multi-uart xSOFTip component you *do* need the external 1.8 MHz reference clock.
