Re: Is the LCD117 able to receive 3.3V logic signals?

I see that the buzzer pin might be more problem than it's worth. I'll probably use a piezo unit anyway, not a speaker. Do the PIC pins correspond to the pins on the DIP chip? i see 4, 5, and 6 on the silkscreen, but can't seem to find 7. Is it not labeled on the board? Or would I have to take that d...

Re: Is the LCD117 able to receive 3.3V logic signals?

I did move forward and use a NPN transistor level shifter with the 3.3V output from the 8266 going to the emitter and the collector going to the 5V Rx on the LCD117. Now another question. I see in the documentation of the LCD117 and the code examples that there are outputs on the LCD117. I see there...

Re: Is the LCD117 able to receive 3.3V logic signals?

I already have a 5V LCD, and I am using a 5V supply. Can I run the 3.3V TX off my 8266 into the RX on the serial backpack and have it work? So the three pins on the Serial Backpack: G - Ground 5V - 5V Power Supply RX - 3.3V signals from 8266 #1 - Will it work properly? Is the 3.3V enough to be consi...

Is the LCD117 able to receive 3.3V logic signals?

I'd like to use an older, through hole LCD117 to display messages from an ESP8266. Seeing that the ESP8266 is 3.3V only, will the LCD117 accept and display Serial print commands at 3.3V? I'm assuming that I'll still have to power it with 5V, which is fine. I have 5V available, I then use a regulator...

Re: Problem with RBBB/Atmel168

By golly, I think I've got it!

Thank you for all your help. I found that I was using pin 13 on the chip, not D13. When I tied to digital 13, it started to work as expected. I am able to communicate and upload sketches now.

Thank you,

Jason

Re: Problem with RBBB/Atmel168

Paul, thank you for the response. I know the holidays can be a busy time, and I'm glad you found the time to respond. Like I said, I pulled the chip off the board and plugged it directly into my breadboard and hooked up all the pins that I though were needed. (Power, Common, Resonator, and a resisto...

Problem with RBBB/Atmel168

Today I assembled my first of two RBBB kits that I got around Nov 7th. The service was excellent, prices were great, shipping costs and response time were great. I just thought I'd get all the kudos out at the beginning. Let me start by saying that I have been in electronics for about 20 years, so c...
