boolpalette in ST7735 drivers

[StuMunsonMcGee]

Do the palette.fg(color) and palette.bg(0) functions work with the ST7735R driver? When I run the following code

#A circle
import gc, math, array, utime
gc.collect()

#Import drivers
from drivers.st7735r.st7735r import ST7735R as SSD
from machine import SPI, Pin

#Define display
screen_h, screen_w = 128, 160
spi = SPI(1, sck=Pin(10), mosi=Pin(11), miso=None)
pcs = Pin(18, Pin.OUT, value=1)
pdc = Pin(16, Pin.OUT, value=0)
prst = Pin(17, Pin.OUT, value=1)
device = SSD(spi, cs=pcs, dc=pdc, rst=prst)

#circle radius and diameter
radius, diamtr = 12, 24

#define framebuffer(s) to be used
import framebuf
fbuf1 = framebuf.FrameBuffer(bytearray(diamtr*diamtr), diamtr, diamtr, framebuf.MONO_HLSB)
x_cent, y_cent = radius, radius #set location
fbuf1.ellipse(x_cent, y_cent, radius, radius, 1, True) #draw filled circle

#define palette and set background color
device.fill(0)
palette = device.palette
palette.bg(0)
palette.fg(SSD.rgb(255,0,0)) #red, circle
device.blit(fbuf1, 32, 68, 0, palette)
device.show()

I get the following error
MPY: soft reboot
Traceback (most recent call last):
File "", line 28, in
AttributeError: 'ST7735R' object has no attribute 'palette'

I noticed that the driver does not include a "from boolpalette import BoolPalette" statement as the other drivers do and it also does not have the "self.palette= " line that others do. When I added them, it didn't seem to help.

Many thanks

You have me stumped :)

Please see this line and this one.

Thanks, that's what I did and regardless of what color I set in the palette.bg() and palette.fg() lines I get a black background and a dark blue (almost impossible to see) image. Any other suggestions? Thanks, Stu

The GitHub history of st7735r.py shows that the file has been unchanged for three years. If you had to modify it to add those lines you must have been using a version older than this, or another driver altogether. I suggest you install the current code and try again.

$ mpremote mip install "github:peterhinch/micropython-nano-gui/drivers/st7735r"

Mr. Hinch That seemed to fix it. One last question if it's not too much, is there a way to rotate the display? I have a 128x160 screen that displays in landscape mode. Can it be rotated to be in portrait mode using yor drivers? Thanks, Stu
