I need to integrate an STM32G071RBT into an existing design with a parallel bidirectional data bus. Based on section 7.3.10 of RM0444, I believe I should be able to do this by configuring my GPIO as open drain. In this configuration, if an external...
I'm new to the STM32L053R8, and I'm trying to emulate a configuration I've used on other ARM M0+ systems. Ideally, I want to maintain a 32 bit counter (physical or virtual) clocked at 32KHz so I have ~30 uSec resolution with a ~131K second roll-over...
Hi I am using stm32l452RC for my project. When I put the MCU to sleep using HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI) all my general purpose timers are not running. I use HAL_SuspendTick() before making the MCU go into sleep ...
I'm using a "blue pill" breakout board and developing with STM32CubeIDE and HAL libraries.When I HAL_SPI_Transmit to SPI1, I get a signal on the MOSI line (PB5), but the corresponding clock signal on SCL (PB3) is a constant 0V. If I run the same code...

Hi all,I am wondering if it is possible to read an encoder using STM32-L476RG without its Enocder-Mode function. If so, how do I do it?Thanks.
There are some devices on the swing table on the CAN bus, when connected to the inclinometer, stm32H743 will fail to send CAN data. The phenomenon of checking CAN bus with logic analyzer is that ERR is generated at the CRC or CHECK bit, and the resi...
Hi, I’m using a STM32F407G-DISC1 board which has 3V power supply.An ADC measures output of op amp. Output voltage is clamped with 3.3V Zener diode. Is the additional 0.3 volts above VCC dangerous for the ADC?
They look the same but I one of them is running the firmware right after plugging the power source, and the other is not. The revision letter is different on both (Y and Z). Is there a way of comparing the changes between both revisions? Thanks in ad...
Hi, I am using this code, TIM1,3,4,8 are working directly like a charm, but TIM2 and TIM5 the only 32 bits timers are taking approximately 1 minute and 45 seconds to be working. Does anyone know where comes this issue? uint16_t buffer1[12] = {0,35,...
