Posted on September 15, 2013 at 14:25Hi everybody i have three primary questions. 1- What's difference between GPIOx_CRL rigester and GPIOx_CRH rigester? B.T.W: yeah, i know these both configure the GPIO to input or output modes and speed of output ...
Posted on September 27, 2013 at 17:34I have a really baffling problem. Perhaps it is not even a problem. It's just something I noticed when debugging my program. Register 3 goes to it's reset value when I return from an interrupt service routine....
Posted on September 02, 2013 at 01:42 The code above is part of a library to control 2 stepper motor for STM32F4. I pretend to use it with STM32F1. 1- Lines 43 to 46 configure the GPIO to Outupo with PushPull, the two lines that I added a...
Posted on September 27, 2013 at 09:17 Dear Sir, I'm using STM32F4-DISCOVERY. I've to run the STemWin on this board with keil RL-RTX. I've made all the necessary GUI and LCD configurations and have added GUI_X_RTX.c from the Segger folder in Keil uVi...
Posted on September 27, 2013 at 16:54HiI'm a bit confused with all the clocks and power saving options on the STM32F3 Discovery board.I'd like to minimize the power consumption by gating all unnecessary clocks and peripherals / memory.The MCU is in ...
Posted on September 27, 2013 at 14:10 Hi I run this very simple code on the STM32F3 Discovery board: int main(void) { __WFI(); return 0; } It compiles fine and I can flash it onto the STM without any problems (I'm using the ST...
Posted on September 27, 2013 at 16:24Hi. Does anybody know where I can find tutorial material about linker scatter-file configuration (meaning, not syntax) needed to match a firmware memory organization with microcontroller memory map? Thanks!
Posted on August 03, 2011 at 08:24Hai, I am using STM32F103ZE I am not getting SPI data correctly. Master is transmitting correctly. But always read as zero where a non zero value has been sent. Master config: (MSP430) The master configuration is c...
