Posted on May 30, 2018 at 12:08Hi everyone,We are using the STM32F427.We have devices that need to work synchronously.So we decided to use PTP but we have no experience in this matter.I have reviewed the AN3411 document to learn how to use PTP.But I...
Several years ago we started a project using an F429 main and 8 F413 slaves, communicating over an SPI bus. In 2020 we stopped the project because of too many problems with ST-provided drivers/stacks, especially Ethernet/lwip and USB, and very poor F...
Code is attached. When the mosquitto server is shut down, the code loops, failing to connect via this call nxd_mqtt_client_login_set(&mqtt_client,MQTTNAME, STRLEN(MQTTNAME),MQTTPASS, STRLEN(MQTTPASS)). After failing, nxd_mqtt_client_disconnect(&mq...
In a current PCB design, SWD debugging is very erratic. Stepping through the code line-by-line works fine, but executing multiple lines will sometimes result in an apparent crash with a call stack like0x08061300xfffffff9which doesn't make any sense f...
HiI am stuck with STM32H743IIT I2S DMA RX ..The code is working perfect when uncommet HAL_I2S_Transmit_DMA (Line 29) but when uncomment line 31 HAL_I2S_Receive_DMA it feedback HAL_OK but do never go into the callbacks ..What can be the issue ?Best re...
There are some comments in STM HAL driver code: stm32f1xx_hal_eth.c "The PTP protocol and the DMA descriptors ring mode are not supported in this driver". Can this driver work with zpehyr RTOS and the Ethernet Rx works in interrupt mode?Also, inside ...
I am trying to create a frequency meter in a STM32U575ZI microcontroller that works with ThreadX and low power consumption using the low power timers LPTIM3 and LPTIM4, as well as an interrupt using EXTI 14. In summary, I use LPTIM4 to count input p...
I am using STM32F407 and want to use USART interface to flash MCU using bootloader. I have external 25MHz oscillator connected to the MCU.I've noticed that there is drastic difference in booting delay time I need to implement on different bootloader ...
