Za zadnou cenu nemohu dosahnout deklarovane spotreby v tomto modu. Ve STANDBY modu je spotreba spravna okolo nekolika uA, ale v STOP modu o mnoho vyssi nez by mela - okolo 200uA. Zkousim na NUCLEO L152RE. Odstranil jsem i externi pull-up z modreho tlacitka. Jiny tam snad uz neni (uz si nejsem nicim jisty). Mam aktivni pouze UART2 a PC0-OUT bez pul-up/down. Vse ostatni v analogovem modu. Zkousel jsem i nastavit hodiny pouze na MSI a ostanti hodiny vypnout, ale pod 200uA se stejne nedostanu. Zkousel jsem i vypnout hodiny pro vsechny GPIO (<span style="font-family: 'Courier New'; font-size: 10px;" class="">__GPIOD_CLK_DISABLE()</span>) ale take bez uspechu.</div><div class=""><br class=""></div><div class="">Dokumentace je prachbidna nebo nevim kde hledat. Podle toho co jsem nasel v datasheetu, specifikaci HALu a apnotes ci v par dostupnych poznamkach na netu by melo byt vse spravne, ale nekde delam zrejme chybu. </div><div class=""><br class=""></div><div class="">Za kazde nakopnuti spravnym smerem budu neskonale vdecny jelikoz se s tim trapim uz vice nez tyden do hlubokych noci az ran a zatim bez zadneho uspechu.
