Hello, i have a ft4232h board with a 74HC595 shift register controlling led indicators, my setup is bank A spi bank B i2c and banks C and D uart. The leds work fine for all banks except bank A spi. Ive searched high and low and know it must exist but cant find any real documentation about debugging the shift register for leds. It seems like a hardware only thing, but i should ask does it require any special bits in the eeprom? Is spi to fast for the leds or is it something else. Im pretty sure i read the normal non shift register tx/rx leds that get setup via eeprom are for uart only, is the shift register way the same and ive been lucky with i2c sneaking its way into working? Thank you in advance these spi leds woukd prove very helpful in debugging.
