Posted on August 23, 2013 at 11:16Good day,Have anybody make it work? I tried the example from:...\STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SDIO\uSDCardBut it does not work. I mean reading, writing functions.. I could only...
Posted on August 23, 2013 at 15:06Hi everyone,I overdrive the low-speed internal oscillator by external source with a small offset and small swing.Where can I find parameters for external clock(without bypassing LSI osc)?Thanks.Eugene #lsi #oscil...
Posted on November 19, 2012 at 00:15I'm using an f405 with USB and want to make the device compliant with USB specifications. Using the HID joystick mouse project from the ST USB library as an example, the chip successfully goes to sleep on USB susp...
Posted on August 23, 2013 at 11:02Although it seems that it is possible to validate a NWAIT input when using FMSC in ASYNC mode, can it be used in Address Multiplex mode? #fsmc-stm32f4-stm32
