Posted on February 15, 2017 at 14:40 Hello:I am trying the demo model STM32F407_DAC.slx in folder STM32-MAT\STM32\STM32demos\Test\DAC\, when I compile this model, there are pop up two windows as follow: but I check the .ioc file no problem.My soft...
Posted on February 14, 2017 at 18:28I read that full FreeRTOS MPU support is available on the Cortex M3, and the M4F. The STM32L4 is advertised as being a Cortex M4 (without the 'F'), so my question is, does FreeRTOS provide full MPU support for th...
Posted on February 15, 2017 at 14:21Hi, I am just coming from anothr controller and learning the different parts of the STM32L0 for low power applications. I am about to start on the 12bit A/D, which hopefully will save me having to add an extern...
Posted on February 15, 2017 at 12:56Hi all,I'm trying to set-up the USART interface.. Very complicated.. but on the debug if I insert a breakpoint on the USART1_IRQHandler the program goes to NMI_Handler.. Why? Thanks a lot.
Posted on February 15, 2017 at 11:48Hello;I am trying to add timeout to my USART reception.I am using USART1 interrupt to start a timer (a sofware timer using system timer). disable interrupt and after time out i should get the data (data packet is ...
Posted on February 14, 2017 at 13:28 Hi, I'm using the PWM to create a sinusoid at a desired frequency and amplitude. I have a table with the values, and I am updating it during the execution of the program. But I have an unexpected glitch th...
