STM32F4 ethernet MII

Pondělí Duben 1 18:54:20 CEST 2013

Jeste abych zanechal nejake uzitecne info, je potreba uzemnit (nebo lepe 
si pres resistor, pripadne jeste na pin MCU) signal TXER - i kdyz se to 
z DS na prvni pohled nezda, to byla druha pricina nefunkce TX. A vystupy 
na ledky maji taky setup funkci po resetu a u zlute nejak nestacilo 
napeti na log.1 - cili 10k na 3V3, i kdyz to je v DS jen pro variantu log.0
Vychazel jsem z projektu MOB_STM32F4-ethernet ktery zde probehl 
http://list.hw.cz/pipermail/hw-list/2013-January/433303.html, je tam i 
hezky funkcni Free RTOS.
