So I have a switch connected via two wires to a two pin plug which is supposed to go in a two pin socket. One pin of the socket goes to 5V and the other goes to a digital I/O in the Arduino + GND (via 10K). When the switch is pressed and the digital arduino pin goes high, stuff is supposed to...
Hi,
I noticed that 4.7k ohm pull-up resistors are used in this circuit on the read/write memory pins: Saundby's MAG 85(scroll down to yellow text), but in other circuits where the read/write / io/m signals are decoded by the 74138 for example, pull-ups are not used? Is it because in the MAG 85...
Hello I need help with FPGA circuit design.
I'm using Xilinx Artix-7 XC7A35T.
Based on the datasheet/userguide, INIT_B pin must be connected to an external pull-up resistor (4.7kΩ) to ensure clean low to high transition.
However, based on the circuit below, we're also connecting the circuit to...
