Today, 13:37Hi, The datasheet tells you all you need to know. If the circuit is not stable then most likely you didn't follow all datasheet recommendations....1 replies | 45 view(s) -
Today, 13:25Hi, I'm not familiar with PIC. With other microcontrollers you have multiple flags. * one that shows that you may write new data to the buffer...6 replies | 156 view(s)

Today, 07:51KlausST replied to a thread kicad - change via pad to IC's pin pad in PCB Routing Schematic Layout software and SimulationHi, The square pad usually is the "pin 1 identifier". Why do you want to change it? I am not experienced with kicad. I assume you need to...5 replies | 80 view(s)

Today, 07:47Hi, I'd say your solution is correct. In the original version there are 8 items in the list, but only 7 x "1" in the K-map. Value "14" is...1 replies | 76 view(s)

Today, 07:40Hi, To me it seems the DE signal is wrong in timing. I don't expect it to change state during any communication. Klaus6 replies | 156 view(s)

Yesterday, 14:30Hi, I rather think this is the "source impedance" or "output impedance" of your circuit. If your source impedance is about 2MOhms and you...7 replies | 115 view(s)

Yesterday, 02:18KlausST replied to a thread Issue communicating to Honeywell pressure sensor to I2C bus in Hobby Circuits and Small Projects ProblemsHi, I don't recommend this. The timing should be controlled by the bus devices, not by additional capacitors. When the slave doesn't...4 replies | 115 view(s)
