Posted on April 17, 2012 at 10:55I am working on Porting over the Stm3240g Board Firmware to the Stm32f4Discovery Board. The Boards both use the same chip stm32f407 - just different pinouts. Obviously there are compatibility issues on the Port con...
Posted on June 11, 2012 at 13:10STM32F103RE I'm using the 2 wire serial debug pins as GPIO under normal operating conditions, the JTAG/SW functionality gets disabled early in the main function. Obviously this would prevent debugging as the debugger...
Posted on September 28, 2011 at 08:12Hi,Im trying to get the usart2 working but for some reason I get random corrupted data when I send message to the STM32F103T8. I can send messages from the STM32 to the computer without any corrupted bytes but no...
Posted on May 09, 2012 at 06:17Like the title says I have a few questions about, all for the STM32F4xx series micro.1. How can I set the micro to use an 8 MHz external crystal to achieve the maximum clock rate of 168 MHz. I have tried using the cloc...
Posted on May 24, 2012 at 10:56Hi, I'm using the emdedded stm32l lcd driver on the stm32L152V8t6 (lqfp 100pin) all segments work well,but on the pb4-lcdseg8 I see a fixed voltage level(about 2.9V) very near to the vdd voltage. the lcd glass is ok....
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 ...
