From: arighi Date: Thu, 22 Apr 2010 21:57:27 +0000 (+0000) Subject: rit128x96: introduce rit128x96_blitRaw() to draw a raw image on screen. X-Git-Tag: 2.5.0~413 X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=d76509a30e7b0ff2440538e2a06210dc64da9214;p=bertos.git rit128x96: introduce rit128x96_blitRaw() to draw a raw image on screen. Moreover, fix the function naming according to the coding style. git-svn-id: https://src.develer.com/svnoss/bertos/trunk@3495 38d2e660-2303-0410-9eaa-f027e97ec537 --- diff --git a/bertos/drv/lcd_rit128x96.c b/bertos/drv/lcd_rit128x96.c index 9922b6af..fd2f3595 100644 --- a/bertos/drv/lcd_rit128x96.c +++ b/bertos/drv/lcd_rit128x96.c @@ -110,7 +110,7 @@ static void lcd_dataWrite(const uint8_t *buf, size_t count) } /* Turn on the OLED display */ -void rit128x96_lcd_on(void) +void rit128x96_on(void) { unsigned int i;
