One of the projects I was working on once required a doubling of clock speed from an Arduino Nano, which has anAtmel 328prunning at 16 MHz on-board. I'm going to explain in this piece how I was able todouble clock frequency with digital logic- no PLL or DLL needed! My challenge?
Device Interface Speed : 芯片的时钟频率 (一般选择默认)1200MHz;Phy to controller clock frequency ratio: 物理层与控制器时钟频率比,即DDR内部时钟和用户时钟的频率比,此处默认为4:1模式,且只有4:1模式;Reference Input max locked memory修改 寻址 Data Memory max locked memory 怎么修改 memory 怎么设置 言...
Another twist with this project is, unlike traditional Arduino clock projects, it does not use a RTC module for keeping time, instead the time for the clock is set from the internet. One big advantage of this is that you only need to set your timezone and the clock will automatically dis...
This lets you keep track of time and build a Nixie clock with just an Arduino board. The Shield comes pre-assembled and ready to go! Plus, you can choose whether the headers will be delivered pre-soldered or loose. Of course, although the Shield will plug into an Arduino Uno, it ...

Arduino's internal timer was not totally reliable for time keeping, the analog PWM outputs did have a very steady square wave of 490Hz. The duty cycle is determined by the value written to the analog pin. (i.e. - 0 is zero volts, 127 is a 50% duty cycle, 255 is a logic high/...
My proposal is to change the Arduino ecosystem, so other libraries could also benefit from this change. Without losing speed when using the 'old' version of shiftIn and shiftOut: See this issue: https://github.com/arduino/Arduino/issues/6561 ...
My program is coded in Arduino IDE. I have to check which version of ESP-IDF has been used and check if this can be updated without any problems. Does this mean that the clock used by CAN is still APB_CLK_FREQ and this value will be 40000 in stead of 80000 in the newer ESP-IDF...
