Problema TFT Touch ITDB 2.8

-

olá todos, este forum tem sido bastante positivo no que diz respeito resolução de problemas e tenho encontrado muitas soluções para dúvidas que tenho encontrado nos outros tópicos, mas ainda não encontrei nada sobre o meu problema!!!

tenho um arduino uno r3 com tft touch itdb 2.8 e libraria que tirei seguinte site:

http://www.henningkarlsen.com/electronics/library.php?id=55
e
http://www.henningkarlsen.com/electronics/library.php?id=51

foi o que me indicaram para poder colocar á prova o tft  :)

tive então de mudar apenas um parametro no código e ele carregou direito e aparece os botões no ecrã para eu tocar mas nada feito!!! já li e re-li mesmo o um ficheiro que vem com o codigo e não tenho por onde lhe pegar!!!

segue abaixo o código:

tive então de mudar apenas um parametro no código e ele carregou direito e aparece os botões no ecrã para eu tocar mas nada feito!!! já li e re-li mesmo o um ficheiro que vem com o codigo e não tenho por onde lhe pegar!!!

o que é o nada feito?
vez imagem ou o touch nao funciona apenas?
olhando ao teu codigo chamou me atençao isto:
code: [select]
void loop()
{
  while (true)
  {
   
certamente isto nada tem ver com solução para o teu problema mas porque é que tens um infinite loop dentro de outro?
o void loop() por si só já é um ciclo infinito.
tens o datasheet tft
como é ligado o touch ao arduino?

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
