The user guide gives this formula: Vout = Vref * DAC12_xDAT/4096; DAC12_xDAT uses straight binary data format, so how to calculate it if it is a hexadecimal number? And it seems that the routines prov...
The following figure is a picture of a 24-bit ADC. I found some information about dBFS. For a 24-bit ADC, dBFS = 20*log(code / 16777216). The maximum is 0dBFS and the minimum should be -144.49dBFS. Ho...
I am using C8051F020. The program needs to apply for a buf of more than 10k, but the on-chip ram is only 8k. I want to apply for it in the on-chip flash area. I wonder if it is possible? I have seen s...
TCK (pin 9) low, but should be high. Please check target hardware ???
The emulator reports an error. It worked fine before and now it doesn't work anymore without any changes?
Thanks!!!...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
