sm16208s and sm5166 panel #702
Comments
true, sm5166 chip is a "type138" line decoder
It's impossible to say for sure. |
I can manage fixing the order of pixels - if that's the only problem. The main thing I'm afraid of is if I can display anything at all, I don't want to end up with the same problem as with this panel, where absolutely nothing is displayed (maybe chips there can't process 3.3V signal? Idk). |
This Aliexpress link does not indicate which drivers are used on the panel, so I can't say what is the reason why the panel did not work. Unfortunately, matrices with unsupported drivers are increasingly common on the market and the probability of getting such a panel is quite high. |
I will probably buy few different models and test which one works best. |
The first option should work, the second definitely won't, LS9930CS - unsupported driver |
Ok so seller informed me that they have two versions of the 80x40 outdoor module I talked about in the first comment. One is ICN2037BP+RUC7258D and the second one is LS9930CS+RUC7258D, and you get a random one... They sent me pictures of ICN2037BP module and it has slightly different pcb layout so it makes sense that mine must be LS9930CS, and that's why it doesn't display anything... |
I need to buy an outdoor panel and want it to work with the library.
I asked sellers and sent them list of supported ICs asking for panels that use the same ones or similar and got recommended this panel, seller says it uses sm16208s and sm5166. They also say that "Equivalent to 138 lines decoding It is the most commonly used line decoding".
Will it work? If not, can I get a recommendation on some 160mm high outdoor screen that is tested and will work?
I also can report on some other panels I already tested:
This 80x40 flex screen does work well (I have a chain of two) with
mxconfig.driver = HUB75_I2S_CFG::DP3246_SM5368;
setting. I would use it but I need outdoor version...This 80x40 outdoor screen doesn't work at all, it's all black no matter what settings I use. Can't tell what ICs it uses as the board is waterproofed.
Edit:
Chips on the working (flex, indoor 80x40) panel:
DP245D
DP5125D
3018SDP
It works with DP3246_SM5368 driver config.
You can safely add these to the supported ICs section.
