我有一块imx6sx主板,使用GPIO模拟串行总线输出,根据手册,设置SPEED = 11,SRE= 1,DSE= 2,发现GPIO模拟的时钟输出只有几百K,请问如何才能提高GPIO的输出频率?
which BSP are you using? could you show me the code? and how do you test it?
Hi,Jimmy
The BSP is 4.1.15,I used gpio_set_value(gpio,0) and gpio_set_value(gpio,1) to generate the clock,and then use logic analyzer to monitor the clock
Anyone knows?
