这个片子好厉害,
如果用这个片子的话,几乎所有的Nucleo板都能点它,点静态字符和图形应该没问题,动态的够呛。
价格怎么样?会不会让破总破产
即便没有冲突,LCD的时序30M;假如用RGB565,并且SDRAM也是16位的话,SDRAM的访问速度也得至少30M。这样的话,在转接板上有两个30M的信号,一进一出,互相干扰。
本身SDRAM就离的主控MCU比较远,而且在Nucleo板上也没做等长,做起来实在没把握能把SDRAM搞定。
总之,有风险。
要不就重新画个完整的板吧,包含MCU 屏幕,SDRAM 等相关部件,这样风险都可控了
我有这块板
果然是大神,曾几何时,我也想在Nucleo上扩展个RGB屏...
算我一个~
