Display TFT ST7789 (OshonSoft Basic).

I leave the library to use ST7789 TFT display, I have translated one that is in C language. But unfortunately I have not been able to get it to work yet. I leave the files in case someone with more experience with these displays can review it.

Now this is weird.

I just plugged the LCD st7789 240 x 240 back in "as is" using the init I already created for the ILI9341.

It worked straight off the bat..

All I have done now is shorten the graphical writes to fit ( I also had to turn inversion on)

Go figure the drivers are the same..

I'll put it on tonight .. Still cant get 16Mhz... must be the breadboard.
The colours aren't as vibrant maybe that's what all the power controls are for.

BUT! Its the exact same code I used on the ILI screen it just worked.. all I did was alter the graphical out put to 240 x 240 and set the height and width to 240.. I'm sure if you have a 320 x 240 it just works.

The INV has to be on as its colours were backwards... The MADCTL BGR may need to be RGB which is bit 4

As requested.


I haven't changed the symbols at all.. I'm running 32Mhz on a pic18f46k22 SPI at 8Mhz

Hi I,

We have colours circles and squares :)
Well done.

Hi,
Yesterday Ian's CODE worked ok, the [ SYMBOL RLED = LATE.2 ] didn't work, so I tried [ PORTE.2 ] and this works. I switched it a number of times, same result.

I tried to copy this working program and correct a few things that were probably my set up interfering with original settings. The original settings didn't work.

Anyway, the CODE sometimes works and sometimes not. I can WRITE working CODE to the PIC, and it doesn't work, then re WRITE it and now it does work.

I switched everything off and on again, I updated the OSH version.
Nothing worked consistently.
So that's been my morning.

I have written to BOTH units more than 10 times each.. I have never had a bad write.

BTW, What programmer do you use? I have pickit3 and IPE v5.10

Hi I,
It's a mystery!
I use Pickit 3 and today I updated to V5.7

I use a USB extension, and just ried directly to USB3 socket, which had better results. So it could be something as simple as new cables and shorter Pickit 3 leads?

What voltage is shown on your Pickit ? I have to turn mine up to 3.6V, which I think improved things?

Bear in mind, a PK3 can only supply VERY limited power, a good reason to upgrade to the much more powerful PK4.

Hi N,
I have a PK4, but seem to remember, that it needs a complicated set up, where PK3 is simple, and not bloated.
Also Ian doesn't have trouble, like me usually and many others.

From what you say PK3 doesn't deliver enough power, do you have any suggestions of a solution?

What 'setup' are you talking about?, you just plug it in - end of story.

Yes, use a PK4 :D

If you've got a TFT on board, then a PK3 will certainly struggle providing enough power for it.

Mine is at 3.3v BUT my pic is on a breadboard powered by a switched mode PSU all comes from the same laptop..

I hardly EVER supply a circuit with pickit3 power as the LCD alone will be too much.

If you have the pic in a "programming socket" fine, but its not good to use the pickit 3 to power... The old pickit 2 was better..

I have two USB leads to my laptop.. One to run the circuit and one to the pickit3.

The switched PSU is one of those drop in 7803 replacement devices... Tons more efficient

Also... One thing to remember!!! If your pickit3 is plugged in all the time " as mine normally is" and you are on an external MCLRE, the pic never resets right... Either put a manual reset button or use the internal MCLRE.. I had this once on a pic26k80 with this same screen. I put a button on and resolved the reboot

Hi N,
Are you saying that the PK4 simply plugs into the PK3 program?
When I looked at it, it seemed to use MPLAB software, which is a big program and does more than i need, as I use OSH/PK3 for programming.

I'm a bit confused about how the MCLR works, the PIC is powered, through the board, and it looks like PK3 doesn't need to supply much power. I think PK3 may need to be set a little more than the PCB voltage, but not sure.

I'm checking the PCB to make sure it's clean and all of the connections are ok.

The PK4 (and the PK3) are designed to work with MPLABX, if you don't use it you could use the MPLABX IPE to use it as just a programmer.

If you're powering your project separately, then the power problem doesn't apply anyway, and you should have the PK3 power switched OFF.

Hi C

Have you ever used the IPE from Microchip? I use it when I program pics.. You just plug it in the same as pickit 3 it is supported by the IPE

The IPE is a stand alone program you do not need to open the MPLAB IDE
