Posted on June 05, 2017 at 00:37I have implemented the IWDG on the STM32F4 and it works without problems. I have the DBG_IWDG_STOP bit in the DBGMCU_APB1_FZ set to avoid Watchdog Faults i.e. when debugging. Did I get it right that the watchdog in a...
Posted on May 21, 2016 at 03:37I am trying to get the Clock Configuration of an STM32F302CB to work. We are using 16 MHz Oscillators. With the STM32F4 I used the clock configuration tool to generate the system_stm32xxx.c file. Unfortunately, I did n...

I am using STM32F407VGT-6 chips.
I use the DMA2 Stream0 with the ADC1 to read analog values. On two of my Boards, the code is working fine and I am not having any problems. On a third Board I programm...
Posted on April 28, 2015 at 23:47Hi,I have a question concerning the clock configuration of an STM32F103RBT6. I used several STM32F4 chips before and generated the system_stm32f4xx.c file with the STM32F4 Clock Configuration Tool. It seems that ther...

I'm using USART with circular buffers and interrupts to transmit and receive.
To transmit, a byte is written to the buffer, the TXE interrupt is enabled and then the byte is sent and theTXE Flag is cleared in t...
Posted on July 01, 2016 at 00:11Thanks I will forward the code to them. I now switched to a discovery-board myself to be able to flash the same project with Tasking and CoIDE. Obviously there are differences, but it is difficult for me to interpret ...
Posted on June 30, 2016 at 22:11Thanks for the fast reply.I downloaded the free IDE CoIDE, Copied the files into a CoIDE project (ARM GCC compiler) and flashed it onto my own board and it also works fine? (Same bus speeds as you mentioned)I tried th...

Hi clive,
I stripped the project down to about 100 lines of code. The only thing that is not included in the code below is the CMSIS and STM32F4xx Standard Peripherals Library and the stm32f4xx_it.c templa...
Posted on June 26, 2016 at 00:02Of course that was a mistake with stream0 and the bits of stream2. I've corrected that. I now have ignored the problem for a while, because it worked. It is totally reproducable: I am using FreeRTOS and FreeRTOS+Trace...
Posted on June 02, 2016 at 18:21Unfortunately, it does not work to configure the clock in STM32CubeMX, then generate the code for an arbitrary project. I tried it for the stm32f407VG and the STM32F302CB. I set the RCC_OSC_IN and RCC_OSC_OUT Pin via ...
