Posted on August 04, 2014 at 09:07Hi. I am new in here with first time to post it. I tried to use the ethernet with LwIP for stm32f407ve LQFP-100. With source of LwIP provided by STMicro electronics, I tried tcp-echo-server. But after working with l...
Posted on August 11, 2014 at 19:24 Hi First of all, I know there are other threads herein which deals with the I2Cx BUSY flag problem, and I have tried the solutions suggested in them to no relieve. Therefor I now, as a last resort opens...
Posted on August 05, 2014 at 23:54 I am trying to use the standby mode on my discovery board in conjunction with digital IO as well as a UART line. I try to send data over the UART then go into standby mode and then wake up to just put out the s...
Posted on August 11, 2014 at 10:21Hi All,i have a strange Problem with my Application using TIM1 CCR4 as TRGO Signal to trigger ADC1/2 (seems to work). The ADCs are in Regular and Injected Simultanous mode. (Dual Mode bits = 0x01). The ADCs are cloc...
Posted on August 11, 2014 at 15:32Hi:Capacitor C124 on STM32 20-21-45-46 G-EVAL is not installed. This capacitor is part of the debounce circuitry for WAKEUP button. There are 2 more button that have the capacitor installed, so I don't understand wh...
Posted on August 07, 2014 at 16:13I have a problem in STMF103C8T7 and I can't find the solution.The STM32 reads corrupt data in array and when reaching a certain memory adress it crashes.The array look like this:typedef struct{int32_t v1;int32_t v2;...
Posted on August 11, 2014 at 09:47Hello.I have downloaded project for STM32F4-DISCO board ( CubeMX 4.3 ). I can export it to IAR, compile and download into board. But I can't turn on any led on board with standard instruction.''GPIOG->ODR=...'' is w...
Posted on August 06, 2014 at 16:06Hello everybody !I try to use the LIS302 (the mems accelerometer of the discovery board).On the datasheet, I don't understand what are the outputs INT1 and INT2, what are the differences?Thanks for your time :) #...
Posted on August 08, 2014 at 20:16I am trying to interface a quadrature encoder with my stm32f4. The code is almost the same as available on ''micromouse'' or many of the other forums. The major problem I am facing is: In debug mode I am able to se...
Posted on August 07, 2014 at 12:20Hi, I already got a project working based on the STM32F030 and with Keil MDK. I based the project on a sample, so it was easy to get a working project. This time I don't have a discovery board with the STM32F071 and...
