Hi All,
I've just fired up my twatch, updated the firmware to enable the backlight, and noticed a possible problem with the LCD.
As the characters are scrolling, each character takes the same amount of time to fade out (terrible refresh rate?), as the characters take to scroll, the effect is most of the time the previous letter is mixed with the new character, making the scrolling text very hard to read.
I also bought the same LCD from Seeed on its own, and my project with that is having the exact same symptoms.
Is this normal, are others seeing this?
Regards
Nick
UPDATE: Video here (6mb), doesn't look as bad as in real life, but you get the idea: http://data.coolnicks.co.uk/dangerousprototypes/lcd.mpg (http://data.coolnicks.co.uk/dangerousprototypes/lcd.mpg)
Adjusting the contrast will help to some extent. It seems the LCD, while 'fancier' than a green/gray model, is a mixed bag with the refresh rate. I'm sorry it's hard to read, let me know if you'd like a refund, I'll request it from Seeed.
