Hello,I use DAC with DMA on STM32F439 (Nucleo board). Now it happens that I create a DAC trigger although all DMA data is sent, ie NDTR has already reached zero. Therefore DMAUDR gets set. When I want to start a new DAC - DMA run I get an unwanted DM...
I am single stepping through simple code. I have two similar similar lines in a loop. Single stepping only goes to the last of those lines. This is STM32F746 Discovery and Keil IDE.while(9) { if(HAL_UART_Transmit(&UartHandle, (uint8_t*)"\0", 1, 500...
I am trying to send 0h, that is one byte with 8 zeros. But HAL_UART_Transmit jumps to the error handler.I am using Keil with 746 Discovery.I have tried if(HAL_UART_Transmit(&UartHandle, (uint8_t*)'\0', 1, 5000)!= HAL_OK) { Error_Handler(); ...
Posted on March 19, 2018 at 07:52Hello,I've integrated the following https://github.com/MaJerle/GSM_AT_commands_parserlibrary(with some changes) ,along with https://github.com/eclipse/paho.mqtt.embedded-cdevice client on STM32F411RET6. I'm using a h...
Hello,I am looking for the MTBF report for part STM32F745VGH6 or FIT value.Thank you!
Hi,We using stdio for debug output in an Mbed OS app. I don't think Mbed OS is particularly relevant to my question. It's just some simple output without flow control or anything fancy.Currently we're using USART2 for our debug output. USART2 wasn't ...
Hey,I am trying to get the internal DMA of my USB HS interface to work. I am using an USB3320 as my ULPI transceiver connected as Device. I have no trouble using the USB interface without the internal DMA, however, it is extremely slow. I only get ab...
Btw. I'm trying to monitor the variables used in code. STM Studio does this under windows in realtime.
I am following this procedure:- set the lock access register for software access, by writing on it the value of 0xC5ACCE55.- set the programming bit in ETM control register- check whether the programming bit is set or not in ETM status register.The ...
Hello all,So I've recently made a new PCB design with a STM32L011D3 chip. I also possess a BMP (bl*ck magic probe), that worked for other projects. So I am unable to see the chip with my BMP , when I do a swdp scan to list devices. The probe detects ...
