RGB p10 MAtrix Panel R1 G1 Pins about dmd_stm32 HOT 18 CLOSED

Hi
please be more specific about your problems with pins. Perhaps RGB Connecting Wiki page will be useful (it is in Russian, but can be easily translated by Google)

As far as i can see in the photo, you have p10 32x16 4scan outdoor panels. Such matrices often have non-standard wiring of LEDs, which must be managed individually. If you are willing to spend some time testing your panels, then I can help you find the right scan type for your matrices.

from dmd_stm32.

RGB Connecting I looked at the sample link page, the panel connections there start with R0 G0 My panel starts with R1 G1 I connected all the other pins as in the example link, but I could not get a picture from the panel. I am using your previous library as a single color without any problems. I could not run this library.

my panel starts with R1 G1 Do you think it's a problem?

I also tried with different Outdoor p10 RGB 1/4 and 1/8 panel scanning, no results.

from dmd_stm32.

my panel starts with R1 G1 Do you think it's a problem?

no,
It doesn't matter. It's just a different notation, the first data pin may be indexed as R0 or R1
so R0G0B0 R1G1B1 = R1G1B1 R2G2B2

Please connect as above and try to run example dmd_rgb_pattern_test.ino

from dmd_stm32.

i will go through the links and test the dmd_rgb_pattern_test.ino example i will let you know

from dmd_stm32.

I tested the connections with socket and solder, I also used the sample test, no results, I activated ALTERNATIVE_DMD_TIMERS from the dmd_config file, I replaced the OE pin with PB9 and the result was like this

#define DMD_PIN_nOE PB9
DMD_RGB <RGB32x16plainS4, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);
fg = dmd.Color888(255, 0, 0);

places i changed
I also tried the other scan pattern

from dmd_stm32.

Please test with RGB32x16plainS4_DIRECT pattern:
DMD_RGB <RGB32x16plainS4_DIRECT, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

from dmd_stm32.

I tested it with RGB32x16plainS4_DIRECT model, the result is like this, I used the same panel in pxmatrix, no problem, I want to use your library with stm32, can my connections be a mismatch in the right pins?

from dmd_stm32.

Thanks for your testings.

I used the same panel in pxmatrix, no problem

What settings did you use in PXmatrix for your panels (scan, scan pattern, mux pattern) ? If you could send an example of code that is known to work with your matrices on PXMatrix, that might be helpful.

from dmd_stm32.

Working example with pxmatrix library
pxMatrix_p10_1_4_scan.zip

scan = 4 scans
hatch pattern = ZAGGIZ
setMuxPattern(BINARY);

The processor I use is atmega 328 Arduino pro mini

from dmd_stm32.

Thanks for code.
This is somewhat strange, such a config should have given more reasonable behavior for the RGB32x16plainS4 mode in my library.
What stm32 board are you using? How do you upload firmware? (STM32_bootloader, DFU or StLink?)

from dmd_stm32.

Hello,
I think that you have to use S2 mux binary not a direct one.

from dmd_stm32.

Kod için teşekkürler. Bu biraz garip, böyle bir yapılandırmanın kütüphanemdeki RGB32x16plainS4 modu için daha makul bir davranış vermesi gerekirdi. Hangi stm32 kartını kullanıyorsunuz? Firmware'i nasıl yüklersiniz? (STM32_bootloader, DFU veya StLink?)

arduino version i am using 1.8.13
I'm Programming over USB TTL
stm32 card link http://dan.drown.org/stm32duino/package_STM32duino_index.json

I just installed from scratch on another computer in your library
the result did not change

sorry, the board STM32f103_C6 is not supported by the library yet, just in plans.

For c6 board a different config is needed because it does not have TIMER4. In addition, the flash size of c6 is relatively small - 32k, and the bootloader takes another 8k from them, so even simple examples from the library cannot be loaded into the board without significant optimization of the stm32 core

I can send you a patch to help run dmd_rgb_pattern_test.ino example on your board, but it doesn't make much sense due to the flash size limitations

from dmd_stm32.

but my card is not STM32f103_C6

my card is STM32f103_C8T6

I noticed that my other cards I use are STM32f103_C6.
I will try and reconnect with my current STM32f103_C8T6 card.

Please select "Generic_STM32F103C series" board in Arduino IDE:

I tried again with stm32f103c8tb
it just keeps getting brighter

maybe the stm32duino library I am using is wrong?

Yes, the package you using is wrong. The only STM32 Arduino package supported is Roger Clarks's repo https://github.com/rogerclarkmelbourne/Arduino_STM32
