1Introduction to Ethernet
The Ethernet peripheral of STM32F20X and STM32F21 can receive and send data according to the IEEE802.3-2002 standard.Ethernet provides a complete and flexible peripheral to m...
To avoid latches, you can pre-assign unconditional default values to variables in an ALWAYS block, as follows:
This is a relatively simple way to avoid latches. I personally think that even if the def...
I use FPGA's 3, 4, 5, 6 banks to connect to DDR1 interface. DDR's I/O voltage is 2.5V, but I connected the VCCIO of these banks of FPGA to 3.3V. What impact will this have on the subsequent circuit de...
The development board has complete documentation and is easy to use. I used IAR7.2.0 + cc3200sdk-1.3.0-windows-installer.exe + CC3x00ServicePack-1.0.1.13-2.11.0.1-windows-installer.exe to build the pl...
