помогите пожалуйста выставить яркость панели P10 32x16 pix…
Делаю часики себе в гараж на одной панельке матричной одноцветной.
через юсб светится тускло, при подключенном питании чуть ярче, но не настолько ярко как с контроллером типа HD-W02 и ему подобным. Есть много ардуинок нано, контроллер покупать неохота.
есть ощущение какого то косяка с библиотекой dmd, попробовал и закомментировал свои эксперименты) как активировать шим на pin 1 enable панели с 9 пина ардуины?
Помогите дополнить код пожалуйста.

The P10 panel can still turn on without 5V Power Input if it only uses one panel, but to increase brightness it must be added with 5V Power Input.
5V Power Input must also be used if using more than one P10 Panel.
