Resolved! how to implement Sleep mode
I am using a STM32L431KCU6 microcontroller and reading data from I2C every 90ms. I would like to implement a sleep mode to achieve lower power consumption, I am using timer6 which generates an interrupt every1ms for system run time. I was thinking I ...
CLARIFICATION REGARDING USING DMA WITH PWM
I am trying to use DMA with PWM data on STM32 I need clarification on few parameters setting and facing few issues.Q1. While configuring DMA for PWM data in tha CUBE MX, there is a option for increment Address and selector for Peripheral or Memory.Wh...
Hard Reset STM32
Hi i want to hard reset my MCU once after 5 minutes is there any way to implement it i know i can do this by NVIC_SystemReset(); but i just want to do it once after power on the mcu
PWM one-shot mode stops working after exactly 427 pulses
Hey all,I am using a B-L072Z-WLAN1 that talks to another of the same board using LoRa peer-to-peer. The board I am having issues with is supposed to receive how many pulses to send from the other board, then send them using pwm one-shot mode to PA0. ...
STM32F777VIT6 VBAT Monitoring
Hi there,We use a STM32F777VIT6 in our application.We tried to use the internal ADC to monitor the voltage of the backup battery.In principle, this works, but we noticed two effects that we cannot explain.The data sheet for the STM32F7 states that VB...
Not able to get UART data on NUCLEO-L073RZ + SX1272 mbed shield
Greetings to all,I'm new with this development board. I download the I-CUBE- LRWAN for end node creation on NUCLEO-L073RZ + SX1272 mbed shield. I tried to send data over UART to my NUCLEO Board, then send it to my Lora gateway but I am not able to re...
STM32H7 connect but Can't program without NRST connection.
I am having a strange (to me) issues trying to program an STM32H743VI.I have had the PCB manufactured and assembled by a different supplier and all of a sudden I cannot program the STM32H743....I do not have the NRST pin back to the STLink-V2, only t...
Ethernet SW Reset Timeout
I have a custom designed board using a STM32F429IET6 and LAN8742A.While attempting to bring-up ethernet and LWIP (fails w/o LWIP at the same spot) the code continuously fails in stm32f4xx_hal_eth.c in `HAL_ETH_Init` while waiting for the SW reset to ...
PWM generation exact number of pulses
We are generating PWM using the STM32F429 TIM10 -- In this call-back function we counting the PWM pulses and , when counting pulse is equal to the total pulse then stop the PWM.But in this code counter are counting the properly counting the pulses bu...
