Posted on June 18, 2012 at 13:16Hello everyone, We're currently evaluating the STM32F4 platform for a sophisticated data logging device. One of the requirements is that 14 digital I/Os need to be sampled at a rate of >1MSamples/s. What we'd like to ...
Posted on December 08, 2011 at 20:04Hi all, I am getting some problems with using SPI peripheral. In the sample code, I see that we have to wait until receiving the ''response'' data after each data transfer. Why we must do that? I mean when we wr...
Posted on June 18, 2012 at 11:00hello can anybody tell me which ccmr and smcr bits to set for filtering inputs in timer encoder modeI tried below setting but no success TIM_EncoderInterfaceConfig(TIM4,TIM_EncoderMode_TI12,TIM_ICPolarity_Rising,...
Posted on June 17, 2012 at 15:35 I am working on some code for the STM32F407 and ran into interesting problem. When switching power to the board off and on quickly, the processor can become stuck on reset, often dropping to hardfault handler. ...
Posted on July 28, 2011 at 02:35Are there any way to configure the TIMx to capture events on both edges for the same input? something like the configuration for capture pwm input. #about-pwm-input
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....
