I'm importing some QSPI code we've been using a few years from an SMT32F7xx project to a new project using an STM32L4xx. Both projects use the same target device. I'm having an issue where the majority of messages don't seem to be sent. After debuggi...
Well, I'm new to the STM32. I'm developing vibration and temperature sensors, which used to be equipped with an atmega.With the new demand for processing I decided to upgrade by putting an STM32L0 in place of the old controller.The problem is that no...
Hi ST-CommunityI am working on CAN Communication in F103When I am de-initializing properly , But when , I am reinitializing it is not workingPlease tell me how to reinitialize CAN Communication if (0 == HAL_GPIO_ReadPin(BRAKE_GPIO_Port, BRAKE_Pin)) {...
Dear all,does anyone have experience with setting analog output signals via Zephyr RTOS? I managed to get the D/A conversion on the Nucleo H723ZG to run via STM32CubeIDE, but I’m running intro trouble when using Zephyr. Apparently a "DAC" driver is r...
I use a board with STM32F405 + W25Qxx. At the moment, I have implemented downloading the firmware file to an external flash memory (via CAN). The process of downloading and verification is implemented in the main firmware. It is necessary to implemen...
Please see this thread from 2018 https://community.st.com/t5/stm32-mcus-products/stm32f4-hsi-accuracy-drift/td-p/360021 The poster complains that the datasheet claims 1% accuracy for the RC oscillator over full temperature range, but other sources (s...
Hello,Thank you in advance for your assistance.I have designed a circuit with STM32F446. I am using an external 25MHz crystal. The main application program runs fine without any issues, and USB communication works. However, on some boards, I am unabl...
At present, when STM32L412 uses the HAL_SPI command to read back the Register, no matter which Register is used, it is 0, but it is normal to use LA to read the data. The waveform is as follows:Is there any unprocessed program that causes the SPI rea...
In the past, we've discussed the fact that in STM32 TIM, there's a delay between Capture and Reset through the derived from the same signal than the Capture. This delay causes period measured using the method called "PWM Input" in RM, to be a couple ...
I have tried setup STM32G071 Sink port and connected with Apple 140w. I want to request 140W but it's seem STM32 not yet supported EPR mode in PD core. Do you have any examples for EPR in STM32?
