Posted on March 15, 2018 at 14:05Hi everybody,i'm using STM32L051T6 MCU and i need to wake up from stop mode using I2Ci've read the last datasheet version and it is possible but there is an errata sheet that reports thati it is impossible.The datash...
Posted on March 13, 2018 at 18:46We have been using processor temperature measurement for a long time with different families of STM32: M3, F3, F4. Only the processor STM32F303RCT6 does not work. The measured voltage of the sensor is 2.22V and is re...
Posted on March 15, 2018 at 11:27Description:We currently use P-NUCLEO-53L1A1 (3 sesnors) to be a fallen-detection sensor product.Instead of putting this interior of ceiling (coz sometimes it has height problem for installing),we plan to put it into...
Posted on March 15, 2018 at 18:34Dear everybody,in my code, i am not able to set my Port PD2 as output.As can be seen, I stopped debug at line 294.In lines 287 and 289 GPIOD->MODER and memory adress 0x4800 0C00 should be set to some value unequal ze...
Posted on March 15, 2018 at 15:35Hi all,I am about the configure the timer frequency which will trigger ADC to continuously scan and convert 5 channels. The callback will be from DMA.The MCU I am using is STM32F407. System core clock is 168 Mhz. Fpc...
Posted on March 15, 2018 at 17:16I am trying to create a custom external loader for the flash chip used in my product. I have looked the example projects in IAR and created myown. I modified the Loader_src.c and Dev_Inf.c file according to my flash ...
Posted on March 15, 2018 at 16:20To begin, this is a board TEST question rather than a design question: Has anyone successfully generated digital In-Circuit Test vectors for the STM32F4xx families using the Keysight 3070 or Teradyne scan tools? I su...
Posted on November 06, 2017 at 11:11Hi, I generated a simple LWIP/UDP project for the NUCLEO-H743ZI using the STM32cubeMX. But the function HAL_ETH_Transmit(&heth, &TxConfig, 0); returns with DMA error . My board works using the example from the S...
Posted on October 05, 2017 at 22:44 I need to read variable length strings from a usart. The strings may be the result of local programming or not. I'm using the HAL DMA receive driver under FreeRTOS. I've found that the following approach works:...
Posted on March 15, 2018 at 14:51I have successfully implemented an initial I2C bus (I2C1) in my custom board design (using STM32F405). I then added a second I2C bus (I2C2) to my design and have initiated it and set it up identical to I2C1. The fi...
