How to disable a strobed port

Hi all, out port strobe = XS1_PORT_1A; out buffered port:8 data = XS1_PORT_1B; out port clk = XS1_PORT_1C; clock CLK_SRC = XS1_CLKBLK_1; set_port_inv(strobe); strobe <: 0; configure_clock_rate (CLK_SRC, 100 , 8); configure_port_clock_output (clk, CLK_SRC); configure_out_port_strobed_master(data, str...

Re: How to change clock polarity and phase

Hi matrix,

Thank you very much for your reply. The functions u specified are not suitable to change clock polarity and phase.

Is XMOS SPI Reference Code is hardwired to SPI Mode 3 (CPOL = 1, CPHA = 1)??

I think not so.

Can u explain ??

Thankyou

How to change clock polarity and phase

Hai all, I want to use XS1-L1 as SPI master. I had problems with clock polarity and phase. For Output ports :: Initially clock polarity is 0 data to be driven on falling edge of clock. If i use set_port_inv() , clock polarity became 1 and data to be driven on rising edge. I want clock polarity = 0 a...

Thankyou for ur reply. I had a problem with stop_port. out buffered port:8 X = XS1_PORT_1A; out port CK = XS1_PORT_1C; out port ready = XS1_PORT_1B; clock clk = XS1_CLKBLK_1; int main() { ready <: 0; configure_clock_rate(clk, 100, 4); configure_port_clock_output(CK, clk); configure_out_port_strobed_...
