RGB P5 MODULE PIN CONNECTION

[tahafathi2013]

im use p5 rgb module. But i have not pin E on my module. Module have R1 - G1 B1 - GND R2 - G2 B2 - GND A - B C - D CLK - LAT OE - GND

Hi, you have a 16scan panel, it is not need a E pin.

If you have a problem with the library with your panel, please show your test code with all connections defined.

[tahafathi2013]

im use this code :

im connected led panel to stm32 pins:

define DMD_PIN_A PB6

define DMD_PIN_B PB5

define DMD_PIN_C PB4

define DMD_PIN_D PB3

define DMD_PIN_E PB8

and connected this pins :

uint8_t custom_rgbpins[] = { PA15, PA0,PA1,PA2,PA3,PA4,PA5 }; // CLK, R0, G0, B0, R1, G1, B1

my panel dont have sclk pin to connect PB7 but im connect this pin to PA15

[board707]

Don.t confuse the CLK and the SCLK pins. The library SCLK pin is the same as LAT pin on the panel. You should connect PA15 to CLK and PB7 to LAT.

[tahafathi2013]

pin connection : P5 - STM32 R1 - A0 G1 - A1 B1 - A2

R2 - A3 G2 - A4 B2 - A5

A - B6 B - B5 C - B4 D - B3

CLK - A15 LAT - B7 OE - B0

Sorry, l am not home now.

[tahafathi2013]

Ok No problem. When you at home chek this problem and help me to fix it.please

[board707]

Do you use a st-link to upload the code to the stm32?

[tahafathi2013]

No im using serial programmer

Try to use pb8 to pin D and pb10 as pin C. Also you have an incorrect order of RGB pins: pins R0G0B0 should be first and then R1 G1 B1

Sorry, I don't have any additional ideas.

[tahafathi2013]

why when CLK pin touched by my finger turned on half?

[board707]

why when CLK pin touched by my finger its working ?

The matrix code uses a high frequency pulses (dozen megahertz) and it is very sensitive to unreliable connections. Do not use separate wires, use dedicated 16pin connector.

[tahafathi2013]

Choose wich cpu spee? Im use 16 pin connector or wires but dont work it. My panel dont have pin E but im remove pin E from code. What is configure without pin E?? Please get me example without pin E to test screen

[board707]

Pin E is not used for matrices with 16 scans or lower, so this setting doesn't matter for your configuration. Honestly, I don't see any problems with your pins setup. I don't have an idea why it not works.

[tahafathi2013]

ok your examples why not working adafruit gfx 1.11 ?? what your panel models tested by your examples stm32 f103c8t6c???

[board707]

The library works with Adafruit Gfx v 1.7 , the link is in the Readme. But your question surprised me, if you would to use incorrect adafrit gfx version, the code doesn't compile. The library tested with dozens of different panels. Your panel looks compatible, your code is correct , and your connections is right. It should work. Sorry for inconvenience, but I don't know how to help you.

[tahafathi2013]

It may be because of uploading the code through serial? It means that it has not been transmitted through the correct serial? Could it be because of the (https://github.com/rogerclarkmelbourne/Arduino_STM32)?

[tahafathi2013]

I change pin numbers to this but not working this time use st link programmer . but not working again.

what use board?? im using bluepill it work on bluepill?

[digi55]

Yes, Iam using also P5 panel like yours and bluepill. Be careful about pin number

[tahafathi2013]

I using your code but not working . Can you upload image from your wire connections an your panel details. My panel not have E pin.

[digi55]

Picture won't help since I'm using a FLAT cable. Pin numbers are as seen in the sample code I sent. PinE is not required on this panel.

[tahafathi2013]

i when use fg = dmd.Color888(255, 255, 255); not change the color.

my wire connections same as sample code.but not working

[digi55]

This code fills the panel with blue dots.

[tahafathi2013]

I change the colors

fg = dmd.Color888(255, 255, 255) But not working.

[digi55]

send a picture of your connections

[digi55]

I will check for you

[tahafathi2013]

Are you install and configure stm boards from https://github.com/rogerclarkmelbourne/Arduino_STM32 ??? Change any thing on your board like resistors?

I burn bootloader by cub programmer. And upload the code by stlink.

[tahafathi2013]

[digi55]

in my code CLK PIN = PA6 you are usingPA15, please change it

[tahafathi2013]

I change it but not working yet.

[digi55]

Sorry ,I don't have any advice

[tahafathi2013]

Sorry ,I don't have any advice

Is it possible that the micro or the micro flash memory is damaged?

This my config for bluepill

[tahafathi2013]

I have sometimes error when upload project
