Help please - CY8C58 family, getting "p3[2] this pin does not support SIO"

LaPe_296836 · ‎Jun 14, 2019

Hi - we're developing on the -059 stick DK, with the MCU CY8C5888.

We're trying to swizzle the bits on GPIO port P3, relative to the data bits on GraphLCDIntf component, working in 8-bit 8080A interface mode. Note that this needs bidirectional IO, with OE pins per port pin.

We get the strange error: p3[2] this pin does not support SIO

AFAIK we're not doing anything to indicate that we need SIO on this pin.

Any help would be greatly appreciated!

Thanks,

Larry

Hi KTrenholm,

Thanks! Actually, it now seems that the problem was the we were routing this I/O pin to an input, but the input buffer was not enabled in the pin dialog box. The error message was definitely not helpful!

At any rate, we seem to have resolved the issue by correctly defining the pins as bidirectional.

Regards,

Larry
