Posted on June 13, 2013 at 16:56Hi,I'm using a stm32f4 discovery board. The data sheet says that my pins are 5V restistant. I have a device that outputs 5V ttl and I want to read this signal. It works, but does it reduce the lifetime of the processo...
Posted on June 12, 2013 at 13:45Hi all, I'm using a STM32L151VCT6. I was hoping to make use of the internal interupt associated with Comparitor 2 (EXTI 22). On further inspection, I've noticed the Reference Manual (RM0038) shows two block diagrams ...
Posted on June 13, 2013 at 11:33Hello, is JTAG faster than SWD? Thank you very much for answer.
Posted on June 11, 2013 at 21:12 Using a STM32L152RB I'm trying to send some data out on the I2C bus using DMA, but I can't quite get the data to transmit like I expected. This is how I'm initializing the DMA. My memory source is...
Posted on May 15, 2013 at 17:36Hi all, I have been using the CPAL I2C library on a STM32F103RBT6 to communicate with an external device which works fine. I have run the same code on a target board containing a STM32F103CBT6, I2C1 is used so I have n...
Posted on June 13, 2013 at 11:43Hello,I am trying to measure the time between the falling edge of a pulse on one pin and the falling edge of another pulse on another pin. I am trying to do it on TIM2 channel 2 and channel 3 on an STM32F0 discovery. ...
Posted on June 13, 2013 at 05:44I'm having difficulty getting a simple timer reload interupt system to work. Once the initTimer() method is called the MCU appears to stop. Even when I comment out ''soloInd->flash();'' Any help at all would be much ...
