Re: Shift Register IC's 74HC164, 74HC165 And 74HC595
Thanks CeaSaR Here are the links for the three boards with shift registers we will be using. https://www.futurlec.com/Mini_74HC595.shtml That one says 'SPI control' (input) and 'output bits' guess those are TTL. https://www.futurlec.com/Mini_TPIC6B595.shtml This says 'a serial stream of data and con...

Shift Register IC's 74HC164, 74HC165 And 74HC595
Hi
Going to be programming the serial in/parallel out one.
What is TTL ? One board with shift register on it says it is TTL. Others say SPI or I2C.
Using PIC 16F84A. 8 LED mini board.
Can post code.
Any tips about this please?
Have a nice day

Re: Compatible NAND Memory Problem
Hi Markkim
Will take a look at manual for the cpu and the programming software and help you figure this out.
Have a nice day

Re: Compatible NAND Memory Problem
Hi Searched zynq and it is a Xilinx product. Seems like their forum would have people that would be off and running with a question like that. Hope this helps a little Just saw your question at bottom. That should be in device datasheet. Electrical specifications section maybe? In programmer manual ...

Re: PIC Assembler 16F872 I2C Overview
Thank you Dale We have been looking into it some more. Section 9 in the 16F872 datasheet. The SPI section is 3 or 4 pages. The I2C section we quit counting at 10 pages. So.It looks like SPI is for us. We do have this SPI helper chip mini board on the way. https://www.futurlec.com/Mini_74HC595.shtml ...

Re: PIC Assembler 16F872 I2C Overview
Thank you Dale Whoops! We meant the module. Master Synchronous Serial Port (MSSP) module. Here is the datasheet for the 16F872.MSSP module is section 9 http://ww1.microchip.com/downloads/en/devicedoc/30221c.pdf What is the general idea for coding SPI and I2C? Configure the registers would be a step ...

PIC Assembler 16F872 I2C Overview
Hi
Could somebody tell us the general idea here please?
We have read the datasheet section on it.
It sort of leaves out 'and do what with it?'.
Thanks!
We do have a RTC 'helper chip' mini board we can test our code with.

Hi
Make that an assembler PIC enthusiast.
Hope there are still some people here that know the 16F84 to 16F887 type assembler.
Going by all the past columns and what not from Nuts and Volts.
Thanks!
