I am using pin PA8 in open drain GPIO output mode to control the power supply voltage on a custom board. Normally, the power supply output 5V but when PA8 is set low, it adds an extra 3k resistor to ground to the voltage feedback pin on the power sup...
I am developing a low-power application and need to add a button-input. As the MCU (STM32WLE5) is in sleep (STOP2) most of the time (waking up by RTC every 30 seconds), the button press needs to trigger an interrupt which also wakes up the MCU.FYI, m...
Hello Everyone, I'm trying to write a float value into my STM32H743VIT6 flash memory, bit it jumps straight to the HardFaultHandler and I cannot understand why... Here's the two functions: HAL_StatusTypeDef Store_AltitudeMax(float altitude) { ...
Hello,I am using a gate driver IC (1EDN8511BXUSA1) that operates with a 9-10V power supply. The IN- input of the IC is connected to a GPIO pin of the STM32L496, which is internally pulled up to VCC with a 400kΩ resistor (as shown in the picture). At ...
I’m designing a board with the STM32F401RBT6 and have decided to use a 48 MHz TCXO for the HSE clock.I’ve written a simple "Hello World" program that communicates through USART.the TCXO i used : TG2016SMN 48.0000M-MCGNNM3 Observations: When using the...
While debugging on the Stm32g474, I enabled write protection. Now I want to disable it. It seems like this is impossible with the Stm32Cubeprogrammer? It will not allow me to enter an invalid address or an address that ends before it starts. How am I...
Hello, I am seeing an issue with an STM32U5 battery powered system in the field. I use IWDG to reset the device in the occurrence of a software issue, and put the device into standby mode to sleep for periods of time before being woken up by either R...
Hi everyone, My requirement is as follows. I must be able to implement Basic DHCP, HTTP, HTTPS, MQTT, FTP, UDP, TCP etc., So I thought of choosing an MCU which has standard working examples and thereby it'll save more time than to adapt a code to a p...
I am trying to create a Client that communicates via Ethernet on the PHY LAN8720 chip. The program has an error that does not run automatically when the board is powered on or the chip is reset. If I use debug, I have to press RUN several times to be...
Hi, I have some code running on an STM32G431 that does a loop in which it reads on a pin on port GPIOB, shifts the value and writes the result on GPIOC. I have trouble really understanding the timing I see on the oscilloscope. The code is: ldr ...
