Posted on February 01, 2013 at 15:27i'm using stm32F103zc using its fsmc 8 bit mode and usart3 (PD8 PD9), can this design work ok? thanks
Posted on March 06, 2013 at 23:17I am trying to establish a connection with the bootloader via USB using our prototype which has an STM32F407. I know the USB FS connection works because our firmware uses it to connect to the PC. Also, I can get the ...
Posted on March 06, 2013 at 15:58Hello, I searched for the reference manual for the stm32f302/303/313 parts but couldn't find it. Id appreciate if someone can provide me the link to it.
Posted on March 05, 2013 at 14:36Hi, I am using STM3240G-Eval , i know that in this evaluation board MicroSD Card shares I/Os with motor control, RS-232 and audio . So i am trying to work around this limitation. I have the following flow : initUSART...
Posted on March 05, 2013 at 14:19hey there,recently I've started playing with a stm32f4discovery with the final goal of realizing the control of a particular simple device we had in our company. It is my first embedded project so I'm quite new to th...
