I meant the addy buss line in the radio. If I understand what you did you were
"serving" specific EEPROM data as requested the uC via the PIC's GPIO lines? Still had to know what addy the uC wanted and still had to put that data on the radio's buss lines in a timely manner, before it released the original EEPROM's CS line and went off to do other things. A dual core 270mhz uC would/should be plenty to process everything before the Hitiachi could blink. Does the ESP32 have enough I/O lines to do every thing in parallel?
