Thu Nov 07, 7: Just saying hello Started by MichaelaJoy Yesterday at 6: For more information on these datzsheet products see: Google [Bot] and 0 guests. My understanding is that the signals need to be inverted between the UART and the connector. It puts out the high voltages.

Somehow I missed this the first time around. Digi-Key and others stock them. Why not just use the UBW I posted the link to in post 3? Media New media New comments Search media. To participate you need to register. Fri Nov 08, 7: After reviewing where we had been on this topic, I’m still not sure I know exactly what you want to do. If you still need the same polarities for some reason keeping in mind that RS line drivers and receivers invert the signala simple inverter will do; otherwise you might be able to eliminate that too, as long as static discharge won’t be damaging the UARTs whose signals get hard-wired to the connectors.

Anyway, I can’t get the board to use the IO. Articles Top Articles Search resources.

Oznog Active Member Dec 15, I’m only using it for the optional memory bank anyway. We don’t NEED no stinking x86! Good afternoon all, I’ve started my first microcontroller project where i’m designing a USB interface to control 32 relays.

I also cleaned up the arduino firmware and added a variable length pagewrite mode. I’m not sure what you meant by “two inverters, two transistors. I also remembering reading that the external clock source needs to be used to achieve higher accuracy to meet the USB standard.

Going to order another one and see. I think the SRAM we are talking about is this: Go to Chinese Site.

CY7C The address pins are wonky, but it doesn’t have pages or anything. Russ Hensel New Member Dwtasheet 12, Thanks to everyone for the corrections and improvements. Have you had any encounters with the PIC18F at all? I still need inverters though. If you need an inverter, use something in the 74 families.

To clarify I’ve added the schematic of the serial circuit. I’m going to stick with what I have. I want to connect this to a device similar to this. Your opinion is extremely important to us, and we rely on customer feedback in order to continuously make improvements and ensure that we are addressing any issues.

A much delayed update: Is it essential that an external oscillator or resonator is used to provide an accurate clock source for the PIC? I don’t think I’ve been clear. Also note that the UART baud rate can only be “tuned” to digitally quantified numbers in the baud field. Thanks for any responses, Pete. Potentiometer Questions Started by norbss Yesterday at You can give me a PM and we can exchange email addresses to share the code.

That is a problem. In general, the internal oscillator IS accurate enough for serial in most cases.
