I often use ZYNQ, and I access FPGA registers through Linux. Recently, I experimented with the Xilinx XC7K325 development board KC705, which is a pure FPGA without ARM. So how do we access FPGA registers? I2C transmits one byte and responds each time, without the need for an additional feedback mechanism; SPI sends and receives … Read more
One late night while debugging the serial port, the waveform on the oscilloscope suddenly started doing the mechanical dance— my Python script, after running for 8 hours straight, suddenly read the temperature and humidity sensor as gyroscope data. This reminded me of the I/O multiplexing dilemma Guido van Rossum faced when designing the prototype of … Read more
