// record the maximum sensor value if (sensorValue > sensorMax) { sensorMax = sensorValue; } // record the minimum sensor value if (sensorValue < sensorMin) { sensorMin = sensorValue; } } 这种方式下,你做的更多读取可能会根据这个最大值和最小值按比例分配。就像这样: // apply the calibr...

If you need to, for example, store multiple strings in an array, you can create an array with multiple char arrays stored within it: char* multichar[4]; char name1[5] = {'j', 'o', 's', 'h',0}; char name2[5] ={'t', 'o', 'd', 'd',0}; or char * multichar[] ...

speedMaximum是时钟, dataOrder(MSBFIRST或LSBFIRST), dataMode(SPI_MODE0,SPI_MODE1,SPI_MODE2或SPI_MODE3)。 SPI中有四种操作模式,如下所示: 模式0(默认值) - 时钟通常为低电平(CPOL = 0),数据在从低电平到高电平(前沿)(CPHA = 0)的转换时采样。
DISTANCE_WIDTH_DECODER_DURATION_ARRAY_SIZE 50 if RAM <= 2k, else 200 A value of 200 allows to decode mark or space durations up to 10 ms. IR_INPUT_IS_ACTIVE_HIGH disabled Enable it if you use a RF receiver, which has an active HIGH output signal. IR_SEND_PIN disabled If specified...
Use itoa function or your own implementation to convert number to char array. You can save about 2KB. See example below./** Converts a number to a char string and places leading zeros. It is useful to mitigate memory space used by sprintf or generic similar function */ void convertTo...
if we want to get the first value of the array, we use array[0] The zero between square brackets is called theindex. Arrays arezero-based, this means that the first element in the array has index zero. This can be confusing at first, for example, array[5] will return 6, where you...
It’s the maximum PWM setting for your output. Normally, the heating resistor is selected, that a maximum value of 255 is allowed, meaning the full voltage (normally 12V) is send to the resistor. The lost energy at the resistor is U2/R. If you increase your voltage above the designed ...
