Posted on March 26, 2014 at 00:32 Hello, I want to decode manchester code sent by RFID chip EM4 I set up a timer as counter without interrupt and EXTI line with interrupt. I am getting an interrupt on every rising and falling edge of the PC.6...
Posted on March 23, 2014 at 20:11 I want to store Device ID inside the flash permanently. So I am using internal Flash of STM I can write&read to Flash in STM After writing the value to the flash, and switch off and then I can read it without any...
Posted on March 22, 2014 at 19:06how can we capture the faults? i read that these memmanage,bus and usage faults can be captured from SCB->CFSR(configurable fault status register) are there any sample pgms to deal with them and also do they occur du...
Posted on March 20, 2014 at 14:22Hello, Does anyone know (has experience) how much time it takes the STM32F101 to reach quiescent current (say from 3mA to 100uA) when entering Stop Mode (from the moment __WFI is executed) or is it instantaneous? Ki...
Posted on March 23, 2014 at 07:57I have chosen STM32F100RCT6 for a new project because of the large number of PWM channels it has. I was not able to activate the clock for timers 12-17, therefore I conduct some more experiments with this chip. Surpr...
Posted on March 24, 2014 at 13:44 Hi All, I'm running some code on Discovery STM32L152 board. I'm getting Hard Fault each time I initiate structure fields in a function: 1. void pid_Init(float p_factor, float i_factor...
Posted on March 25, 2014 at 13:24stm32cubef4 uart examples does not work on discovery f429?! It seems ST new tools have no check before release and they are not perfect and reliable for projects.
Posted on March 24, 2014 at 18:59Hi,i want to start an interrupt to leave the sleep mode after a precise that my ADC reads.Could some body help me and put what i shall do in a nut shell?thank you for your attention PS: i am using an stm32f0 discover...
Posted on March 24, 2014 at 21:28Hi,I want to make a timer to count on each rising edge of a square signal on PC.6. I am using STM32F103RBT6. I searched a sample code for that, but I couldn't find anything. What I found are all about timer interrupt...
Posted on March 22, 2014 at 10:18My application board has STM32F405RG microcontroller. I tried to use a project came from STM32F4 Discovery Board by just changing the microcontroller from Keil manual ''Project\Select Device for Target 'ST Link Flas...
