Blueteeth Well-Known Member May 27, I use the 74HC or theboth work quite well. I tend to use 3 wires though, and the 4-bit mode interface. D7-D4, RS, and backlight.
E tied to the strobe line.

With a couple of NAND gates dataseet can have a ‘busy line’. I’ll post if people want it. I have been using the 74HC but it never dawned on me to tie the strobe and E together. I would like to see what you are doing with the busy. It was challenging trying to figure out how to drive 6 pins on a type display with only 5 outputs on the PIC.
The host device sends a byte of data as two serial bytes with 4 bit nybble data in datashedt b The 12F samples and latches the b D7 lines and sends the E strobe right in the middle of the RS serial data bit when it arrives. I finally got around to building and testing the design a couple weeks ago and so far it’s working flawlessly at and datxsheet.

I plan to try baud soon. Incredibly nice demo and layout btw. Anyway, you mentioned that you’d like a better lower Vref for the A2D module for the LM35 and I was wondering if you or anyone knew if the Comparator module voltage reference module in the ‘F88 can be used for the A2D Vref signal? Also, which C compiler are you using for 16F’ devices? Is it a ‘free’ compiler, by any chance? I really need a website to put datahseet this crap on Futz, You may have misunderstood me.
I asked if anyone knew if you could use the comparator voltage reference for the A2D module. I don’t know for sure that it can.

Bill blueroom showed us his 8 bit SPI latch on another thread which can be used for an LCD display amoung other things and I’m currently adding 4-bit latch capability to my 12F serial LCD driver using a new control bit in each serial byte that will enable or disable the E strobe for that byte. Thanks for the tip about BoostC. I’ll take another look at it. You may have misunderstood me. Let us know if it satasheet out?
Have you ever looked at the uber flexible comparator module on the 16F Until yesterday I didn’t even know what a comparator was.
Well, I kind of had an idea. I just hadn’t looked at them in any detail.
A quick google search found this. What happens when you have less? The successive approximation thing doesn’t work right, I guess? You must log in or register to reply here. Replacement Transformer Started by ncag 20 minutes ago Replies: Datasheets, Manuals or Parts.
