I have a STM32F091 Nucleo-64 and have the basic RS232 UART examples (ComPolling and IT) from the Cube working.I need to implement RS485 and was hoping to find a basic example to build upon.I'm currently going through the STM32Cube_FW_F0_V1.9.0 exampl...
Is there any easy way to get to the newest contributions in above thread? It is over 100 entries long and to get to the bottom, where newest contributions reside, requires tedious scrolling, clicking, waiting for reload, scroling, clicking ... etc.Is...
Nowadays nobody has single core CPU where project is building, so this option should be enabled by default, or configurable in CubeMX.
Hello,We're looking at using a STM32F303RE for a project. One of the requirements is being able to measure the frequency of a square wave ranging from 1MHz - 40Mhz. I've been looking at the General-purpose timer cookbook (AN4776) and trying to get...
In my STM32F72xx/3xx project, I'm not allocating memory dynamically, i.e., I'm using neither malloc nor free. And I'm restricting myself to C, with no C++ parts.Is there a reason I shouldn't set the heap size to zero? Do any of the drivers, HAL or ...
There are multiple alternating functions for one peripherals. Why and what is the difference?
Posted on October 02, 2017 at 10:39Hi, In the HAL_RCC_DeInit function, switching the SYSCLK to MSI only uses this function CLEAR_BIT(RCC->CFGR, RCC_CFG_SW). But, to select MSI as system clock source, I think that it is required to use after that the...
Hi,I'm trying to use Armadillo (http://arma.sourceforge.net/docs.html) with the above mentioned STM32 MCU.The goal is to use it for the inversion of a dense, symmetric, positive semi-definite Matrix (actually a convariance matrix) with float values (...
