Posted on May 25, 2012 at 15:58Hi,I am new to this forum and I am programming the STM32L-Discovery using Crossworks.I am currently trying to do something which I believe should be relatively simple. e.g when I touch the 1st quarter of the slider - d...
Posted on January 27, 2012 at 09:48Update:Ok quick update I have now edited my code to only use DMA with the ADC and software trigger (DAC_SoftwareTriggerCmd) the DAC and it works fine. Therefore it seems to be a DMA issue. The new implementation I ...
Posted on June 10, 2012 at 19:07Hi there, I would like to know if there is a way to protect your binary image in a stm32f device (with mpu). With protection i mean that i would like to secure the binary image that runs on the device from been stolen...
Posted on June 12, 2012 at 13:21Hi, I am new to the STM32 micro-controller. I am using STM32F207 board to communicate with another custom micro-controller board. The communication is basically sending commands and receiving response using USART6 ISR...
Posted on June 11, 2012 at 20:03Looking at the STM3210B evaluation board schematic, the 8Mhz crystal has a 1M resistor in parallel across the crystal. Looking at the STM3210E evaluation board schematic, the 8Mhz crystal has a 390 resistor between ...
Posted on June 09, 2012 at 15:13I have a STN LCD (that have only 24 segment and 1 common)-at 3.3 volt. Can I use stm32f103 to drive it directly?(by 100Hz toggling segments with respect to common pin) Is there any note for this method? Is there any ...
Posted on June 11, 2012 at 10:32Hi, Can anyone recommend an RS485 transceiver that can be used with a STM32 UART in half duplex (one wire mode) ? I've considered an ST3485E but would need extra GPIO lines and software to drive the receiver and driv...
Posted on May 17, 2012 at 15:43Hi, I would ask for recommended Graphic Libraries to use with STM32 controlers. I 've found the ''Resource Editor for Embedded GUI Library'' developed by ST, but there is too few proprieties associated with each object...
Posted on June 11, 2012 at 09:32Hi, I was wondering if I can power the Discovery board via the VDD pins on the headers? I want to use 3.6V rather than the 3V used so I can get a larger more accurate ADC reading (0-3V6 rather than 0-3V). How would th...
Posted on May 26, 2012 at 16:53Hello, Is there any document that describes each Peripheral , and every bit of Register, for STM32f100x microcontrollers , there is nothing in Datasheet , for instance the USART is described only in 4 ...
