Connect with SPI, TypeError: function expected at most 5 arguments, got 6 #4

Hi Peter,

I copied and pasted the files (freesans20.py, ssd1306.py, writer.py and ssd1306_test.py) per your instruction, and connected the pins per the comments (using SPI) in ssd1306_test.py, and run test(True), but I got:

TypeError: function expected at most 5 arguments, got 6.

I tried to track it according to the line number, appearantly it came from: ssd = SSD1306_SPI(WIDTH, HEIGHT, spi, pdc, prst, pcs), so I checked class SSD1306_SPI(SSD1306) in ssd1306.py but couldn't understand why it gave an error - everything looked right.

I was using a PYB Nano.

Thanks for the help in advance. Kaiyuan

I suspect that you're running an old version of firmware: there was a change around the new year which affected the SSD1306 driver. A prior version will produce these apparently inexplicable errors. Please upgrade your firmware to the current build and try again.

Hi Peter,

Thank you. You were correct. It worked after the upgrade.

Thanks for the help. Kaiyuan
