STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on May 20, 2013 at 09:18Hello,I'm running my code on STM32F103 chip, I've set up a PWM output from timer1 with period of 200 ms, pulse width 5 ms, it's working and can be seen with a scope on GPIOA_8. The thing is, that I want to do something...
Posted on May 20, 2013 at 22:38I am using a STM32F407 and have set it up for using USART with DMA. I have some problems with the RX part. What is the best way to sync the enabling of the RX DMA with the remote transmitter? If I enable it in the midd...
Posted on March 14, 2013 at 20:55Environment is an STM32F205VF on a custom board, but the problem has also appeared on a STM3240G eval board with an STM32F407I. Compiler is GCC 4.6.2 at optimize level O0 for debugging. My application has extensive ...
Posted on May 21, 2013 at 16:55Hi, I'm testing the f4 and the fpu. I have a small fpu test like this:volatile float a=0;volatile float b=.1;int c;for(;;) { GPIOD->ODR^=0x8000; for (c=0;c<100;c++) a=a+b; }So by looking at PD15 ...
Posted on May 16, 2013 at 13:53Hello,I'm using the STM32F4 on the discovery evaluation board.I wrote a simple function that calculates the mean of a vector. When the code is starting to make the summation it goes to HardFault_Handler...Here is the m...
