<div>To je dobry modul ale nebude mit dost
UARTU, i kdyz nechapu na co tolik... Jeden je pres USB STLINK,
jeden je tusim na pinech a to si nejsem jisty a to je cely.<br>
Tlacitka taky nic moc, to same ledky, displej je ovsem skvely. <br>
Se softwarem je to taky otazka, asi CUBE knihovny a priklady by
pozadavky celkem splnily...<br>
Vykon a pameti OK.<br>

<div>Zdravim,<br>
potrebuji nejakou vyvojovou desku s ARM procesorem:<br>
- 2x UART RS 232<br>
- 4x UART TTL - 5 V, 9 bit komunikace<br>
- Nejake vstupy vystupy<br>
- Tlacitka,<br>
- AD - trimr<br>
- LCD textovy (Ale nemusi byt, muzu pouzit UART a
zobrazovat to na PC)<br>
- Trochu pameti, staci par mega RAM/ FLASH<br>
- Trochu rychlejsi procesor, rekneme 64 - 128MHz<br>
- EEPROM 16KB<br>
- cena nehraje az tak velkou roli, ale levnejsi veci
se snaze prosazuji.<br>
<br>
Podminkou je ale funkcni vzorovy projekt, kde buduu
vsechny potrebne knihovny a bude poctive napsany aby
sel prenest na ruzne kompilatory. Obcas je treba neco
vyzkouset a neni na cem.<br>
<br>
