T113-S4的DDR3时钟能936MHz吗?
T113-S4没详细文档,想了解下它的DDR3时钟能到多少?
根据大佬的D1H的Tina到了936M,而T113的Tina是792M, 这个咱们能按936M来么?

回复: T113-s3 适配EMMC(THGBMJG6C1LBAIL等)持续更新!!!
贴主,做板验证了吗? 查了下T113-s3的SDC2的引脚PC2~PC7内部是参考VCC-IO的,一般是接了3.3V,eMMC的VCCQ接1.8V会起效?

T113的LEDC怎么控制超过32个的灯
大家好,LEDC FIFO是32个深度,如果超出32个灯,像100个这样,怎么编程呢?现在产品上要用它来做,效果比3个PWM或者IO来好用多了,就是32个灯的突破要怎么编程还不知道怎么搞

回复: R528-s3点7.84" MIPI屏
GT911 接45P普通平板电容触摸屏的小板,大量便宜外屏可用了,一般45P的都是14x26的,如台电P20HD的。我这有3种类似外屏都是一样的45P.参数都能用一个。
网盘先上,里面有打版gerber和原理图, asc是可导入pads成PCB,也可用AD导入成PCB。HQ_R528资料

R528跟T113差不多,基本参考它就行。
LVDS好搞,如果参数不行,把分辨率改了后,直接用以前OK的时序先顶上调调看。 -
回复: R528-s3点7.84" MIPI屏
更新下动态,类似板型已经在产了,这个板基本引出了所有功能并经过了验证。准备上架核心板。
做了7.4" 1280x400和 10.1" 1280x800两种竖屏,使用G2D旋转后Framebuffer就是横屏操作,这点真的很棒。
外壳原型打印回来,喷上漆挺好看的,5个按键通过硅胶帽接触按压,很柔软舒服。下面是10.1的,使用了G+G的普通平板外屏,做了GT911的电容屏小板,用产测工具固化好参数,就能使用便宜量大的平板G+G了。
10.1的竖屏真便宜现在, G+G也只要18,

@xiaowenge 暂时没用上它, 先预研下, 现在在用7.36" 1280x400和8" 1600x480的,这2货是LVDS横屏,但市场不多了。
刚好G2D有旋转功能,可以直接当横屏用了。 用过S3点6.86那时候还是得CPU去做旋转,有动态效果时CPU都到90%了。 -

R528-s3点7.84" MIPI屏
7.84最常见的量最大的应该是维泰的,但型号和生产日期太多了。于是点起来了,这不重要,
重要的是手上有3个规格,如WTL078401G05-24M, WTL078401G04-24M, WTL078401G01-18M
每个都有不同的生产日期,拿WTL078401G05-24M来说,我手上就有2017,2018, 2022,开始是LT6911C点的, 除了04-24M外都正常。
放到R528上,只有05-24M的2017, 2018正常, 用逻辑分析仪抓包看,在初始化时最开始果然多了一个0x05写,这有坛友知道怎么来的么?
之前10.1 800x1280竖屏和1920x1200横屏挺正常,就没抓包看。这个是多次抓包都会有这个0x05写命令在,所以可以排除逻辑分析仪测量错误,不过上百个初始化数据里面可能会有2,3个抓错的,多次抓对比一下就行。
