It's this display:

Using the same exact interface (4 wire SPI) as the other SSD1306 128x32 displays.

I just tried my trusted gLCD_SSD1306_Buffered component with a 128x64 pixel display module instead of the usual 128x32 pixel displays I have used before. It works, except it skips every other line and hence only renders out 32 lines instead of 64. Changing the display pixel height under properties b...

Went to the post office this morning to pick these up

Thought I might bump this one a bit

It was very repeatable. I rebooted my workstation and still the exact same thing with this component. All my other programs with different components have been working just fine.

I'll attach the test program.

I just tried changing the jumpers on the display module to 6800 Parallel interface and then changed my test program to use the fLCD_SSD1322_Parallel component instead. But as soon as I hit the compile to hex button (after I have saved it) flowcode immediately stops responding and I have to shut it d...

Ben, Have you or anyone else successfully used the gLCD SSD1322 _buffered component? It seems to be using the 3-wire SPI inteface and I have set the jumpers on the back of the display to configure it to 3-wire SPI but I don't get anything printed on it. Also, the SSD1322 chip can display 16 gray lev...

The PCBs have been shipped from OSH Park on Thursday last week so maybe they'll arrive next week.

Still waiting on the OLED displays. They were sent out on the 13th via China Post so it can take a while longer if we're unlucky

Great, thanks for clearing that up for me

Ok, so the pin number doesn't matter at all, only the pin name for example if I want to output "1" to RA0 it will be on pin 2 for one package type and pin 28 on the other package type?

I wasn't sure so I thought it would be best to check

Hi, I would like to use the PIC 18F24K22 in the 28-pin QFN, UQFN package but when I choose this chip in FC it shows the chip in it's 28-pin PDIP, SOIC, SSOP package. The pinout is not identical and differ quite a lot. So what needs to be done for me to use this chip in the package I need? Thanks PIC...

Ben, could you please try to add a macro to the SSD1306 buffered component that allows us to simply paste a byte array like: img [] = { 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x7, 0xe0, 0x0, 0x0, 0x3f, 0xf8, 0x0, 0x0, 0x7f, 0xfe, 0x0, 0x1, 0xf8, 0x1f, 0x...

Well that was part of the problem but the big problem seems to be the timing of the sample period.

Any suggestions on how to go about this would be great.

I might have found a reason for my problems with the FFT. I didn't understand that the FFT needs both negative and positive values to work but it should have been kind of obvious with the calculation box "data=data-512"

I'll have another go and see what I can come up with.

Hi, So I've been struggling all day today trying to get the FFT DSP component to work. For some reason I thought that it would be possible to run the DSP components on 8 bit PICs and not exclusively on 16 bit PICs but I got all sorts of errors trying to compile my test program when having an 8 bit P...

Ok, try this baza1pub file. I have changed the CheckBuffer from 10 to 100 and also changed the delay in the main loop from 1 second to 100ms. baza1pub.fcfx It sounds like it starts out fine with "1, 2" but then something happens. Maybe the CheckBuffer time was too short and/or the delay was too long...

I've designed and ordered the PCB's and I've also ordered some displays. Hopefully they will be sent out before the Chinese New Year begins on the 15th...

Hi Mikn,

I haven't tried simulation nor on hardware.

Perfect! Thank you.

I'll order a few tomorrow and start drawing the PCB for it.

As soon as I get them I'll send you a couple.

I would really like to see an adaptation to the great SSD1306 Buffered component so that it allows us to choose which interface (SPI, I2C etc.) and also what size/resolution. The resolution is kind of there already since we can select either 128*32 or 128*64 but now there's a new even smaller displa...

Ok, I've had a look but I don't know what is causing your problems. First I would try to create an even simpler program than your client1pub and baza1pub. I've made an attempt at a new client1pub and baza1pub that only uses two bytes in the buffer and the baza1pub should display one odd and one even...

Hi Mikn, I have very little experience from RF stuff and don't own any MRF49XA but I'll have a look at your attached programs and see if I can be of help. I will be back home in a couple of days hopefully (where I have my computer with FC on). Feel free to remind me if you haven't heard anything fro...

Right, I can relate to that description all too well

Hi Mikn,

If you don't mind sharing your low level program (through PM if you don't want it public) I would like to have a look and maybe we can get a custom component made for it.
