I'm not a hardware engineer, so apologies if this is a stupid question ...I have two STM MCUs communicating over an open-drain line which has a pull-up resistor. Each MCU has a GPIO port connected to the line, and the ports are configured open-drain,...
I want to interface temperature sensor LM35DZ with STM32F103C8T6. I wanted to know whether we need any signal conditioning circuit between the sensor and the STM32 or not. If yes, then I wanted to know the exact circuit using voltage divider and the ...
Hello,I'm working on an STM32F411 and I'm using two peripherals : one SPI and one SDIO.The SPI is triggered every millisecond in a timer ISR and is using two DMA2 streams 0 and 2 in direct mode at a very high priority for TransmitReceive. Then, the D...
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?
