stm32H73** sleep mode
Hi, My test board can enter sleep mode OK, but doesn't wake up when PC13 goes high: (never reach __enable_irq()) void Sleep() { __disable_irq(); SysTick->CTRL = 0; // Enable WKUP4 (PC13) PWR->WKUPEPR = PWR_WKUPEPR_WKUPEN4; // Enable WKUP4 PWR->WKU...
STM32F407 Ethernet LwIP + FREERTOS ping break Hard fault
Dear team,I am facing an issue where my device disconnects and drops the ping whenever the master device tries to connect with RS-485 Devices. after some "request timeout" error the device goes into a hard fault.The application runs on STM32F407VET6...
change of dead band issue in PWM
Hi,i was trying to change dead time from (244 value to 100) for every 10ms in a loop. But its not updating , the set dead time is 244 in the PWM waveform. Though my dead band register ( DTG) is updating at every 10ms. I am updating TIM1->DTR2 if(en...
, ETH[FIN, ACK] and HTTP GET retransmissions
Good morning. I'm running an STM32F767Zi on a custom board, LwIP 2.1.2, no OS. The device acts as a HTTP server. I've got an issue where I get GET requests and [FIN, ACK] packets retransmitted by the web browser.192.168.5.106 - Client192.168.5.196 - ...
Help regarding proper interrupt configuration for PWM and DMA
Hello !I am using DMA with pwm and working on unipolar SPWM.i have configured DMA with an array of pwm and is working fine. i am trying to get the interrupt after either each DMA transfer or after the reload of ARR register. According to the document...
Two Axis High Speed Encoder Input Connection to STM32H755
Hello,I am working on a project to design an IO controller board using STM32H755 (LQFP144) mcu. I want to interface two axis of high speed encoder inputs to the mcu. TIM1 and TIM8 timers are used. Could you please review the attached schematic design...
STM32U LPTIM Autonomous Mode
I am using the LPTIM3 with LSEAn external input is used to trigger a capture.The STM32U575 spends most of the time in STOP MODE 2.To keep the LSE active in the LPTIM use the following instruction:_HAL_RCC_LPTIM3_CLKAM_ENABLE(); // SET_BIT(RCC->SRDAM...
Battery charger SMBUS interface to STM32U031R8
Hi,Can I interface SM Bus of battery charger chip to one of the I2C port of STM32U031R8? If yes, what care I need to take from hardware perspective?Thanks,Pradeep
Power consumption of my HW
good morning,I am actually working on my STM32G431KB, I will use the power consumption tool of STM32cube once my code is complete but I would like to know if for now my calculations are correct.I want to use my board to power up 11 different sensor ...
