micropython-93cx6

A library to interface with EEPROM 93cx6 series with micropython.

It's a basically a port of nopnop2002/esp-idf-93Cx6

I tested this library with ABLIC S93C56 with ESP32.

API

• Device.ew_enable(self) -> None
• Device.ew_disable(self) -> None
• Device.ew_enabled(self) -> bool
• Device.erase_all(self) -> None
• Device.erase(self, addr: int) -> None
• Device.write_all(self, value) -> None
• Device.write(self, addr: int, value: int) -> None
• Device.read(self, addr: int) -> int
• Device.read_sequential(self, addr: int, length: int) -> list

How to transfer script

I recommend to use scientifichackers/ampy

Example

You have to specify GPIO Pin number in a script.

This example should output a dump of 93c56 EEPROM(16-bit origin).

import eeprom_93cx6

eeprom_93cx6.__DEBUG = False

# specify gpio pin of cs, sk, di, do
dev = eeprom_93cx6.Device(
    model=56,
    org=eeprom_93cx6.EEPROM_MODE_16BIT,
    cs=12,
    sk=13,
    di=14,
    do=15,
)


# dev.ew_enable()
#
# dev.write(0, 0x01)
# dev.write(1, 0x02)
# dev.write(2, 0x03)
#
# dev.ew_disable()

def dump_buffer(buf, start=0):
    num_lines = len(buf) // 8
    for nlines in range(num_lines):
        addr = (8 * nlines) + start
        print(f"0x{addr:02X} ", end="")
        for v in buf[nlines * 8 : 8 * (nlines + 1)]:
            print(f"{v:04X} ", end="")
        print()


buf = dev.read_sequential(0, 128)

dump_buffer(buf, start=0)
