Sigfox and SSD1306

[alexlont]

Im trying to create a Sigfox signal tester using the return RSSI using a Fipy and a SSD1306 OLED
im getting an error in relation to SSSD1306. i have a script from the following.
https://github.com/pycom/pycom-micropython-sigfox/blob/master/drivers/display/ssd1306.py
i get the following error

>>>

my main.py code is below

from machine import I2C, Pin
from network import Sigfox
from ssd1306 import SSD1306_I2C
import socket

#i2c = I2C.init(0, I2C.MASTER, baudrate=100000, pins=("P10","P10"))
#INITIALIZATION AFTER POWER UP
i2c = I2C(0, I2C.MASTER)             # create and init as a master
# configure the I2C bus
i2c.init(I2C.MASTER, baudrate=400000) # init as a master
oled = SSD1306_I2C(128, 32, i2c, 60,external_vcc=True)

sigfox = Sigfox(mode=Sigfox.SIGFOX, rcz=Sigfox.RCZ4)
s = socket.socket(socket.AF_SIGFOX, socket.SOCK_RAW)
s.setblocking(True)
s.setsockopt(socket.SOL_SIGFOX, socket.SO_RX, True)
s.send(bytes([0, 1, 2, 3]))
r= s.recv(32)
print(r)
rssi=sigfox.rssi()
print(rssi())
oled.text(rssi, 0, 0, 1)
oled.show()
s.close()

i2c.writevto

this looks like bug should be writeto

[jcaron]

@livius The new version uses i2c.writevto, though, which does not seem to exist in Pycom firmware (at least it's not documented, didn't check an actual device or the sources).

But the error message should be slightly different, the error shown clearly points to the older version of the driver.

@alexlont
Are you sure that you are using this new one?
There is no start command in the new code.

@livius I've updated my SSD1306.Py script to refect the newer library. however im still getting the exact same issues.

Pybytes configuration read from /flash/pybytes_config.json

SSSD1306

It is quite old. Try to use it from official micropython it use framebuffer then
