uClinux system transplantation based on FPGA and implementation of web-server[1] I have been working on the operating system on niosII recently, and finally implemented a web-server. I would like to s...
Measure six-phase voltages, set the timer2 to 10ms as the reference for the delay. In addition, the output comparison is 500us. In the output comparison interrupt, the software triggers the ADC to sca...
I read a foreign paper about active filters. What does 3-dB frequency at 1 Hz mean? Here is a whole paragraph: All the analogue signal conditioning paths concluded with a corresponding unity gain four...
Does anyone know what the setting up time and sample/update rate MSPS often mentioned in DA chip datasheets mean? Also, what is the fclk (which seems to be the parameter given by Maxim)? Do Maxim's fc...
This chip. Is it a fixed sampling frequency of 1MHz, and the SPI transmission speed can reach up to 20MHz? Is this the correct understanding? eeworldpostqq...
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
