Posted on April 16, 2015 at 00:44Hi friends.My problem is the next: STM32F103 adc + dma transmits only low byte of adc data... The same code via adc EOC interrupt presents the whole 12-bit words. I hope, that i missed something very simple. I use AD...
Posted on April 10, 2015 at 12:25I'm using a stm32f429 running at 144MHz and I wanted to implement a periodic two-channel adc conversion. I need to make the conversions on a 1us period and I'm considering in using a dma adc conversion. I know how to...
Posted on April 15, 2015 at 15:23I am using the STM32F429 and are using a timer in output compare mode. It works as expected, except that it toggles the output on overflow as well as compare. Is there some way to disable this behavior? I am using th...
Posted on April 12, 2015 at 16:50Hello everyone! I am using STM32F103RET for my project. I need to communicate by SPI with a low speed digital device with the speed of at most 1KHz clock. At the same time, I need to have my own cpu clock as high as ...
Posted on April 13, 2015 at 12:14Is there a publically available defect tracker for STM32Cube? Given the complexity of the offering, and the numerous bugs listed in these forums for various different versions/processor targets, wouldn't it be very h...
Posted on April 14, 2015 at 15:33Hi,I want to use external SRAM with the controller STM32F429. i want to make use of internal supervisor circuit, which is used to power the internal RTC and internal 4Kb SRAM, to backup the data in external SRAM. for...
Posted on April 14, 2015 at 13:47I have setup a timer in PWM input mode. It all works well. I have setup the prescaler and period counter so I can measure down to 10 Hz. But if the input frequency is too low (< 10 Hz) the timer will wrap around.If I...
Posted on April 14, 2015 at 21:51 Hello, I have function fifo_read(RxFifo, &rx, 1) which reads byte from FIFO buffer. I want to use this function in two different interrupt handlers. I have declared rx variable as fo...
Posted on April 14, 2015 at 23:01I've made several custom STM32F4 boards.Never any problems, until now, when my JLINK detects my board ONLY, if I press reset button before I press detect device in Keil uVision.When I press download button I got erro...
Posted on April 14, 2015 at 19:40Hi I've got some problems getting this to run. In RM0090 register description starts with CR1 (offset 0x4). Within the Hal files I found a reference to the gcr (offset 0x0) register. However, I can't find any info fo...
