Posted on June 13, 2014 at 15:51Hello, I have a problem to configure two interruptions in the same time. The first one is to receive data from UART, the second one is to send data to motors. After several successful itterations, UART Status stops at...
Posted on June 11, 2014 at 14:26I have an array of unsigned short numbers from sensors. The data will be multiplied with an array of floating point numbers.To use FPU provided by STM32F407, I need to convert the unsigned short numbers into floating ...
Posted on June 13, 2014 at 09:05Hi, I'm testing the two discovery STM32F429 and STM32F407. What I've done so far is that the 429 sends data to the 407 through UART4. The 407 interrupts at every character received, and all works fine! If I do the opp...

Posted on June 12, 2014 at 02:03 Why do I get an immediate update event when I configure TIM7 like this: TIM7->CR1 = 0; TIM7->PSC = 7199; TIM7->ARR = 2000; TIM7->DIER = 0; TIM7->CNT = 0; TIM7->CR1 = TIM_CR1_CEN; while ((TIM7->SR & TIM_SR_UIF...
Posted on May 25, 2014 at 19:09Folks, The STM32L051 looks like a good device for a new project, but there seems to be no-one stocking it and there seems to be no dev kit. Can I use the STM32F0 discovery and any code will be essentially drop-in when ...
