Posted on March 25, 2013 at 10:39Hi, We are trying to migrate from IAR Kickstart kit with IAR-STM32F207ZG-SK board to our own board. On our PCB we have STM32F207ZC mounted. The small test code is successfully downloaded with J-Link. Downloaded C:\da...
Posted on October 05, 2014 at 10:08Hello, I use your microcontroller STM32F407(lqfp100) at my work. We develop at the research institute a system of control engine. I developed a program at STM32F4 Discovery. But when I developed my scheme where use...
Posted on October 06, 2014 at 09:53Dear all,We are trying to use the on-chip ADC of STM32F407. We have read two appnotes, which are AN4073 How to improve ADC accuracy when using STM32F2xx andSTM32F4xx microcontrollers and AN2834 How to get the best ...
Posted on October 03, 2014 at 17:09Hello,I'm trying to identify when program is on debug mode or not.As semihosting (interrupts) breaks the program when it calls printf(). I hope to read a flag to identify that i'm not on debug mode and with this I ...
Posted on October 03, 2014 at 14:28Hi, I'm facing with a strange problem, in fact I'm working on Discovery platform to study the stm32f4 low power modes. I'd like to enter and exit from sleep mode and to do this I use an UART to send the command to ...
Posted on October 03, 2014 at 16:14Using the STM32427, with TIM5 set up as a master to TIM1 and TIM8. This works fine; I get synchronous pulses like I expect. However, I'd also like to have TIM1 act as master for TIM4. When I enable TIM1 in master m...
Posted on September 26, 2014 at 15:29Hi, I configurated the PB4 pin in iterrupt mode, every time you shoot the interrup the led is toggled. If the source code is compiled in start address 0x800 0000 it's ok, the interrupt it's ok and the led is tog...
Posted on October 01, 2014 at 17:23 HI, I want to read the value of a potentiometer; I have this ADC: #include ''stm32f4xx_adc.h'' #include ''stm32f4xx_gpio.h'' #include ''stm32f4xx_rcc.h'' #include ''pwm2.h'' void adc_configur...
Posted on October 02, 2014 at 19:55Hi everyone, So i wanted to get into ST ARMs microcontrolers. I only used TI Tivas before but i wanted to try out the ST ones.Well i would like to know if anyone could provide some links to tutorials and such. My m...
