Posted on January 02, 2014 at 16:26Hello, I have been trying some waveform generation using DAC + DMA. This works quite nicely, and I am now generating I + Q waveforms for a small SDR radio project. Just to see what cand be done, I have pushed up th...
Posted on October 26, 2013 at 14:31Hello everyone ,In Discovery board , by default 2 DAC channel activated . I want to activate only one .Is there anyway to configure this ? I am trying to modify DAC_Init ()..but :( ..... #dac-stm32f4-discovery-b...
Posted on October 18, 2013 at 09:50HII have a small issue with the DAC in a stm32F103, there Is a small offset between DAC_DHR12R1 and DAC_DOR1 registersThe code is pretty simple:DAC_InitStructure.DAC_Trigger = DAC_Trigger_Software;DAC_InitStructure...
Posted on September 18, 2013 at 00:22Hi all,I'm working on STM32L-discovery board and currently I'm trying to configure two analog outputs with DAC. I am able to see the result from the output pin but there seems to be some bias from the zero refer...
Posted on April 10, 2013 at 15:44 Hello, I'm using a STM32F4DISCOVERY to program the firmware of my future board. I want to use the integrated 12 bit DAC of the board to generate analog simple signals on the A4 and A5 pins, but I don't wa...
Posted on March 28, 2013 at 21:34 hello dear forum, I write 2048 to STM32F4 DAC, it gives 0.83V instead of 1.65V if I write 4095 it gives 1.65 V instead of 3.3V the output of DAC is input to an OPAPM amplifier I mean it i...
Posted on March 07, 2013 at 20:46On the STM32F3-Discovery, PA5 is connected to the L3GD20 gyro chip's SCLK input. In general CMOS devices to not like having input hanging around voltages in between a good Low or High. It causes excessive current co...
Posted on September 05, 2012 at 04:38Hi All, I had the DAC working using DMA to out put a sinewave continuously and it seems to have stopped working when I tried to change which timer I triggered off. After changing the timer configuration back it s...
Posted on December 19, 2012 at 15:08Hi all, In comparator section of reference manual of stm32f30x devices. It is mentioned: ''Cycle-by-cycle current control loop when combined with the DAC and a PWM output from a timer''. What does it mean? Is th...
Posted on November 13, 2012 at 11:33I was planning on using an STM32F103RE in a design where the DACs would be part of a control loop, and will need to be used in 12 bit mode. Unfortunately the DAC specifications in the datasheet show extremely bad...
