Posted on November 20, 2014 at 21:22 Hi guys, I am working on the L3GD20 embeeded in the stm32f3 discovery board. I came with this code which gives me 0 on the 3 axes even when i move the board. any suggestions please? #include '...
Posted on November 21, 2014 at 00:44Hi, we are developing a couple of STM32 boards. Want to target the mbed platform. For programming, we would like an optional small daughter board that can plug into our board, that provides the programming/debuggi...
Posted on January 03, 2013 at 22:11Hi everyone,Whenever I use either of the multiblock read/write functions the peripheral gets stuck in the SD_CARD_SENDING or SD_CARD_RECEIVING state, respectively. Further attempts to access the peripheral in this ...
Posted on November 19, 2014 at 17:29Hello,I'm having problems with bit timing configuration. I have 36MHz peripheral clock and need 500kBit/s on CAN. I'm having trouble, because I've calculated right value but I see on the oscilloscope that it isn't...
Posted on November 19, 2014 at 17:07I am having trouble to wake up the STM32F407 from the STOP condition using a GPIO EXTI line (PB 0). The same GPIO line is used when the STM32 is ON to switch it OFF (THIS WORKS PERFECTLY) and whenever it is OFF ...
