Posted on June 14, 2012 at 03:33Hi Guys, I'm designing a 3-phase DTC induction motor control which needs the 3-phase voltages and 2 of the currents. I am using the STM32F4 Discovery board. The control will have a small sample time (5uS). The control...
Posted on June 14, 2012 at 15:55On the STM32F103C8 chip I can use the PA9 default alternate function to use either USART1_TX or TIM1_CH2 on that pin depending upon which peripheral is enabled.If both peripherals are enabled and I am using PA9 as USA...
Posted on June 13, 2012 at 09:35Hi, i am newby with arm cortex m3. I am working on STM32F101xC and i have this problem: driving a lcd with 8080 interface with FSMC i have no problem with st-link debugging and after a ''reset pin'' reset. After power...
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...
