I'm using the UART (USART5) with RS485 and I have enabled the read to be on also when sending. I need to read back the data that was sent to see if it is correct. The problem is, that I do not receive what was sent. But if I send the same data from o...
I am currently using the STM32F412 microcontroller with an operating system (OS). Normally, everything runs smoothly without any issues. However, I have encountered a situation where my threads fail to enter under specific conditions. It's worth noti...
How to get temperature (degC) from the STM32G491x internal temperature sensor?I have my ADC working and producing raw count values. Eg: 303.So assuming a working voltage of 3V3 and maximum count value of 4095 then I assume that I must multiply the ra...
I am unable to make working ThreadX USBX Host example for STM32U5 adopted for Nucleo-U575ZI-Q.All, but the last setup step described in Introduction to USBX section 3.3 complete properly, but when finally HAL_HCD_Start() is called, ThreadX crashes. W...
Hi! I have working on the watch Dog implementation in STM32F446RET6.The board which I have used is NUCLEO-F446RET6.I have followed the below mentioned steps, 1. Enabled the IWDG in system core using CubeMX of STM32CubeIDE. (which takes the LS...
Hey all,I’ve recently encountered an issue with setting up the CAN module on my STM32F4 and hope that someone is able to help me:After buying the SN65HVD230 CAN Board, I tried to set up the MCU so it can communicate with the CAN Bus. For that I solde...
Hi, I am new to STM32. I have a STM32H723 nuncleo board where I want to sample 8 bit data from the on-board ADC at the maximum frequency of 3.6 MHz. Then I want to directly transfer the data to a SD card using DMA with SPI. Preferably I would want to...
In the STM32L562 reference manual (RM0438), v7.0, the section 11.6.13 "GPIO register map" is missing the registers MODER and PUPDR (which are documented in the preceding sections).
Hello,I'm planning to use the STM32G474 to read a pulse width. This width is a delay value in nanoseconds.I'm wondering if there is any possibility to use the High resolution timer (HRTIM) for that operation.I would use the events to trigger a rising...
Hello everyone,I'm working on a project where i use 2 STM32 MCU which communicate with each other with LPUART and DMA.My STM32 references : STM32L072CBT6 and STM32L010C6T6I have a problem with this communication with LPUART and DMA. I see that error ...
