Input/output error for luma.oled

[lmcpith]

Type of Raspberry Pi

Linux Kernel version

5.4.0-139-generic

kindly suggest a version of luma that can work with linux ubuntu. might be timing or handhake. using oled 128x32

Expected behaviour

trying to use luma.oled library under linux ubuntu oled is well detected and well mapped under i2c but and mapped as 0x3c, visible hoping to use this library under linux ubuntu 18

Actual behaviour

    device = ssd1306(serial)

what device are you using? can you link the datasheet or seller link?

HIbranded from china probably, part number is cm009605v4it works with arduino, I was retesting with Linux ubuntu

Identical behaviour on latest Fedora Linux/x86_64 6.3.11-200.fc38.x86_64 Kernel and 2.42" ssd1309 i2c 128x64 module from here : https://www.aliexpress.com/item/1005003091769556.html I needed to short D2 as explained to get it visible at 0x3c.
The same example (terminal.py) works fine with two other smaller i2c modules based sh1106 and ssd1306 chips. However with this one, starts and fails after a second-two working. Typically: ... i2c_rdwr ioctl(self.fd, I2C_RDWR, ioctl_data) OSError: [Errno 5] Input/output error

FYI, the module as HW on same host works well with this driver: https://github.com/armlabs/ssd1306_linux

I was retesting with Linux ubuntu latest Fedora Linux/x86_64 6.3.11-200.fc38.x86_64 Kernel

Anyone can test this on Raspberry Pi OS? I don't have such a device so won't be able to test..

Any updates on this issue? having similar problems with ssd1309 on rpi4
