pimoroni / microdot-phat Goto Github PK

I just got started with my Microdot hat, and made a simple clock that shows up in a mirror, so I needed to set both set_rotate180(True) and set_mirror(True).

The digits of the time show properly, however the decimal places, controlled by set_decimal(), now show up at the TOP of the numbers, not the bottom (as they did before the rotating and mirroring).

I haven't fully tracked it down yet, but it looks like the call to set_decimal() in function show() does not account for mirroring or rotating.

Hello
Tinkering with microdot-phat for a tutorial and noticed that a "-" character is not supported. Code fails on this character every time.
Error text

Line 29 is where this happens

for line, text in enumerate(lines):
    lengths[line] = write_string(text, offset_x=offset_left, offset_y=line_height * line)
    offset_left += lengths[line]

I'm parsing an RSS feed using feedparser and the list I create is working, but second entry in the list has a "-" in the headline.
Cheers!

Just wanted to point out something. Perhaps it's somewhere in the documentation that I didn't read or was broken to begin with...

I had modified the canned clock example to flip the display and set the brightness to a lower value. This was working great until this evening when I did an apt-get update and got some new libs.

The error is:
Traceback (most recent call last):
File "./clock.py", line 16, in
set_brightness(0.4)
File "/usr/lib/python2.7/dist-packages/microdotphat/init.py", line 311, in set_brightness
_mat[m_x][0].set_brightness(brightness)
NameError: global name '_mat' is not defined

Obviously, somebody didn't get initialized and to fix this problem one needs to call show() before the set brightness call.

Just pointing this out as something that changed, in case it was unintentional.

Currently "clear" does not reset scroll position, causing confusing drawing weirdness. Investigate whether this should happen/what else should happen to the buffer when clearing.

For some use-cases, it will make sense to add 180 degree rotation support.
I will investigate, how mus work this will be and if I can support this.

Attempted to connect one up via wire jumpers instead of just plugging it onto a Pi.

Connected pins 1, 2, 3, 4, 5 & 9, but it's not being detected via i2c-detect. What pins need to be connected?

Following this guide returns...
