Hey everyone,
after getting a 2.9inV2 display by waveshare to work (besides the partial refresh bug), I tried out the 1.54inV2 one in order to get something with a working partial refresh. While the 2.9 one shoes a crispy clear image, the 1.54 one looks super “noisy” or “checkered”:
(1.54 upper left, 2.9 lower right)
Same ESP32 (doit devkit 30pin), same power supply (usb from laptop), identical code besides obviously the display part:
2.9 (working):
display:
- platform: waveshare_epaper
cs_pin: 21
dc_pin: 3
busy_pin: 22
reset_pin: 1
model: 2.90inv2
rotation: 90°
update_interval: 15s
full_update_every: 1
#reset_duration: 2ms
id: eink
lambda: |-
it.image(0, 92, id(otter_icon));
it.printf(150, 0, id(font1), "Hey, it is");
if (id(outside_temperature).has_state()) {
it.printf(190, 20, id(font2), "%.1f", id(outside_temperature).state);
}
it.printf(150, 50, id(font1), "degrees outside");
it.printf(150, 70, id(font1), "and it is");
if (id(outside_weather).has_state()) {
it.printf(150, 90, id(font2), "%s", id(outside_weather).state.c_str());
}
1.54 (noisy image):
display:
- platform: waveshare_epaper
cs_pin: 21
dc_pin: 3
busy_pin: 22
reset_pin: 1
model: 1.54inv2
rotation: 90°
update_interval: 15s
full_update_every: 1
#reset_duration: 2ms
id: eink
lambda: |-
it.image(0, 164, id(otter_icon));
if (id(outside_temperature).has_state()) {
it.printf(10, 10, id(font2), "%.1f", id(outside_temperature).state);
}
if (id(outside_weather).has_state()) {
it.printf(10, 30, id(font2), "%s", id(outside_weather).state.c_str());
}
I actually sent back the first 1.54 that I had as I thought it was a hardware issue, but now I get the same behaviour with the next one i ordered.
Anyone got any ideas what could be the issue?
Thanks a lot in advance!
