Posted on October 14, 2012 at 17:22Thank you for existence of such driver. But this driver is unsigned. Virtual com port is very useful for many applications. It is very hard to use unsigned drivers for clients. As ST makes any other drivers and sig...
Posted on June 06, 2012 at 11:30Hello, Always, when I set on the clock in I2C1 or I2C2, in the status register SR2 is the BUSY bit set. Here the code:int main(void) { I2C1_DBG = (I2C_TypeDef *) I2C1_BASE; // for debugging RCC->APB1ENR |= RCC_APB1ENR...
Posted on October 12, 2012 at 15:51Hello,I'm using the CPAL library.During the ''CPAL_I2C_Init ()'' when the I2C clock is set on, the BUSY bit in the status register SR2 is always set too. Why the BUSY bit is set ?I'm using the I2C1 on a STM32F217VG...
Posted on October 13, 2012 at 20:32I need to measure from outside the sampling frequency of a STM32F4 discovery, I have thought about using a pin as an output, and bring it in an alternating manner to VDD and GROUND each time the DMA takes a sample ...
