Hi Ben

So far as i remember, the clock phase etc works only with a certain setting
and the CS is always de-asserted on startup, its one of the first things that
is done, CS only toggled on macros for reading/writing.....

Maybe i should the PLL 64mhz on the FC7 version compiler i have as a process ...

Hi

I have a 18F46K22, using FC6 (6.1.2.0) that uses a device on spi bus

running the processor on 16mhz, with Fosc/4 (4mhz spi) setting for spi bus....i get correct
operation of the device(ADXL345 acc)...device_ID register correct (0xE5)

If i run the processor at 64mhz PLL....with Fosc/16 (also ...

i have downloaded the latest version of FC7.....does this also include all the updates/patches
as mentioned above?

Hi Ben

I found the problem :)

Once PLL is enabled config and osctune, the osccon (bit 0/1) must be set
to both 0 (primary clock set as source)....its counter intuitive but correct
because when PLL is enabled it takes internal osc first into the PLL block
and then outputs as the primary source ...

Hi Ben,

I tried all 3....no luck, i am sure all the control registers
are set correct as well

Hi

I have a 18F46K22...Flowcode7 V7.2.1.4

I wish to run at 64mhz PLL, and have set all the parameters
correctly, config setup / compiler speed / osccon / osctune
with 1sec led test....it flashes led at 4 sec intervals which
tells me the compiler setting is correct but the other settings also ...

Hi

Any answer to this question about driving the OLED library through
hardware SPI?

Hi Leigh

Would it be possible for you guys to have the SSD1351 component driven
by hardware SPI ? The current bit bash method is just too slow when doing
updates on the screen.....

With the hardware spi option available i can clock the data much faster
and that would be a great feature to have

I ...

Hello

Is there a string function in FC that allows you to search for a
string within a string?

Or has anyone done an example of how to do this? I have some ideas
but would prefer some example that has already been done

Thanks

Mark

Hi Leigh

can you also please give me the component glcdssd1351 update/bug fix
with exposed data/command for Flowcode7?

i do work on the latest V7 as well

thanks

mark

will try it little later....just asking FC vers for now

Hi Leigh

Thanks....is that file for FC6? i am trying this on FC6

thanks leigh

will see how i get on with the existing libary

i may setup a hardware driven library (spi port) and see how it goes
if it works i will post here for others to use....

Hello

has anyone perhaps used the Si7051 temp sensor from Silabs?

having a hassle trying to get data out of this guy, uses I2C
but i cannot really make sense of their protocol

Also i am not sure what address to use...they say they
have 7 bit base address (0x40)...with 8th bit as W/R
100 0000 ...

Hi Leigh

yes i did swop the settings around....it always leaves a small section
with random pixels not cleared
But as u say.....prob best to just set it to 128X128....instead of 128X96
My display is physically 128X96, and states so in the datasheet
It is rectangular in shape

Another question, the ...

Hi Leigh

OK....the component works now....but an oddity

My display is 128X96 pixels, so when the initialization is done
it only fills the background about 3/4 of the way (white) and the
remaining 1/3 still has random color pixels

If i declare the screen to be 128x128 then it fills the ...

Thanks Leigh

I will try give it a bash today and give you feedback

In the meantime did you find anything in the existing
component code?

Hi Leigh

OK.....so hard spi is working....i can fill red/blue/green screen

where to from here?

I have some pcb's made already that were setup for the FC macro using
software bit bash and relevant control signals as posted above.
So although the hardware spi is working.... i cannot use it on the ...

Hi Leigh

Something weird going on with this component macro

When i issue the initialize command (using data/command send or the normal one)
the clock just keeps running and the data is stuck high. Also the assigned CS is also
stuck high
I put this into a loop with 1sec delay to scope out the pins ...

Hi Leigh

Thanks for the external commands

Before i can setup my own "initialize" macro, is it possible to
tell me or show me what is going on in the flowcode initialize
macro command?

there are quite a number of things to setup, so it will be very helpful
to see what the standard initialize is ...

Hi Leigh

The extended set is disabled

The processor is running OK.....led reality test

See attached FC file.....there are 2 macros to turn OLED on/off
which is working OK

Just cant get image

Hello

I have an OLED display connected to 18F46K22 (int osc 16mhz) working with FC V6.1.2.0

Connections are as follows:

1. CLK RA2
2. DATA RA1
3. REG SEL RD3
4. CS RE0
5. RESET RD2

These are all general I/O as the clk / data is bit bashed as explained before

The display also has the required ...

Hello

Been using a 18F46K22 for sometime now in TQFP package, without any problems.

Using FC6.1.2.0

changed chip package to smallest one UQFP, but now the uart2 TX is not working.
i can toggle the pin as a I/O no problem, but when i try send a string there is
nothing doing....same code....nothing ...

Hi

The other day i started getting this message at compile attempt (various
project files all doing the same)

Hello

I have a SSD1351 OLED display that i would like to use (datasheet indicates 4 wire SPI connections)
SDIN / SCLK / CS / DC / RES
serial in / serial clock / chip select / data..command / reset

1. Looking at the graphic display component from FC6 "SSD1351" i am not sure if it
uses hardware ...
