Big clock edit and customize #55

Closed elpaul closed 5 years ago

elpaul commented 5 years ago

Hello everybody. dhrone - good job! I changed the time zone and clock format for 24 hours. It works perfectly on Volumio 2.555 and HD44780i2c 20x4 display. What do I have to do to remove "AM/PM" text behind the clock? BR

dhrone commented 5 years ago

Remove the ampm widget from the stoptime and stoptimeweather canvases.

So change... 'stoptime': { 'widgets': [ ('time',10,8), ('ampm',75,8) ], 'size':(100,32) }, 'stoptimeweather': { 'widgets': [ ('time',0,0), ('ampm',65,0), ('temphilow',75,0), ('conditions2',0,24), ('temp',75,24) ], 'size':(100,32) },

to... 'stoptime': { 'widgets': [ ('time',10,8) ], 'size':(100,32) }, 'stoptimeweather': { 'widgets': [ ('time',0,0), ('temphilow',75,0), ('conditions2',0,24), ('temp',75,24) ], 'size':(100,32) },

Glad to help. What display are you using? It looks interesting. Could you recommend a part # and supplier?

Winstar WEH002004BL I bought in Poland at a local store for the equivalent 25 $. link It is very aesthetic and clear. At the beginning I wanted to run it on the winstar_weg driver, but the display did not work at all. But working good with i2c converter + HD44780i2c driver. One problem is initialization after soft reboot. I have to turn off power each time. In the manual I found information that I should send 5 times 0x00 with delay of 100us and omit the busy flag, but I do not know how to do it. (I'm not a programmer.)

It's interesting that the winstar_weg driver did not work for you. I just double checked that which driver chipset the WEH002004BL uses and it is identical to the WEH001602 (WS0010). The winstar_weg driver has more features than the HD44780 especially with custom characters. Which i2c converter are you using?

elpaul commented 5 years ago

Exactly, exactly. I bought it for it. It puzzles me too. I spent two weekends over this oled, but without success. Tested in 3,3v and 5v at RPi 3A+ & Volumio 2.565 WEH2004 has two WS0010 controllers, maybe this is the reason? In the end I took the i2c converter from the old LCD, soldered and ... the display runed right away,( but as 44780). The converter is on PCF8574 link

Hi, how can I change the time zone and clock format for 24 hours?

hcanning87 commented 4 months ago

Hi @elpaul , I know this thread is ancient, sorry! I am having exactly the same problem as you did where the OLED display works perfectly until you soft reboot or restart the pydPiper service - a hard power off/on is required to get it to initialise properly. I have tried getting it to send 0x00 5 times in the hd44780 driver file but this just results in a blank display. Did you ever get to the bottom of it?
