Bug in Python3.6 standard library when compile using MinGW

Python36 is compiled by Visual Studio 2015 or MSBuild tools 2015, which included Compiler v19.00 (MSC_VER 1600). But “C:\Python36\Lib\distutils\cygwinccompiler.py” can’t handle it… I modify it simply like this:

Bug in data2mem…

I using data2mem to replace data in BlockRAM, It confused me when I try to replace BlockRAM data in Spartan6 Devices. There are correct in BRAM16 with 8bits and 16bits, only error BRAM18 with 18bits. Update: bug exist in ISE … Continue reading

发现STM32的SPI2有问题(invalid)

最近需要用到SPI1和SPI2协同工作,想弄个2位的SPI通信: 硬件的接线如下: SPI1.SCK -> DEV.SCK SPI1.SCK -> SPI2.SCK SPI1.MOSI -> DEV.MOSI[0] SPI1.MISO < - DEV.MISO[0] SPI2.MISO -> DEV.MOSI[1] SPI2.MOSI < - DEV.MISO[1] 将SPI1设置为Master方式,将SPI2设置为Slave。 设置为CPOL=0,CPHA=0(就是不传输的时候时钟是低电平,上升沿采样,下降沿更新数据)。 具体的配置就不贴了,在stm32fwlib的例子里面有。 注意:官方和网上能用的配置都是SPI1是Slave、SPI2为Master!接下来会说。
