Resolved! STM32 Product Recommendation
Among STM32 boards, I would like to recommend a board that includes an interrupt 2 or more pins, I/O (Analog) 20 or more pins, MCLR (reset), PWM signal (more than 2 pins), AVdd, AVss, Vss, RX, TX, ICDCLK, and ICDDATA pins. This is the first board I'm...
Resolved! STM32H7: UART IDLE is set again without RXFNE be set.
I have the problem on my STM32H753, that the IDLE-bit is set when transmitting. On the manual it says: The IDLE bit is not set again until the RXFNE bit has been set (i.e. a new idle line occurs).The RXFNE is never set (actually on CubeIDE this is sh...
Resolved! STM32H753: Can't receive the data the controller is sending
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...
Troubleshooting Thread Entry Issues in STM32F412 with OS and Motor Control
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...
Resolved! Getting temperature from STM32G491x internal temperature sensor ADC
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...
USBX and STM32U5 crash
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...
Resolved! Regarding IWDG maximum timeout duration to reset in STM32F446RET6.
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...
Resolved! CAN register not taking any data - STM32F4
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...
Resolved! STM32H7 - ADC to micro SD card with sampling frequency of 3.6 MHz possible?
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...
