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 June 14, 2012 at 07:10Hi there, Can someone explain what is the role of the mpu? From what i understand, it is only for OS purposes, meaning that whatever the mpu configuration is made at boot time, can be changed again by the user from a...
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 June 13, 2012 at 17:12Hello everyone, I'm working on STM32F207VE Kit . Has anyone ever set the frequency to exceed the limit for APB2 (greater than 60 Mhz).Yesterday, I had set up freqency for APB2 is 120Mhz (by my mistake). To day, the pe...
