Posted on July 16, 2012 at 12:02Hello, Can someone please explain to me how the alternate function mapping works? I found the alternate mapping table in the datasheet but how to read it. What is the default location of peripherals. For example by d...
Posted on July 09, 2012 at 12:33i try to use the spi interrupt , but the whole program just hanged at case 101 which is in the void GYRO_Task(void), it shows me ''+++''. anything wrong? here is some part of my code. #ifdef GYRO_SPI_USE_INTERRUPT ...
Posted on July 06, 2012 at 10:02Hi, With a STM32, I have a problem to select either EEPROM (M24LR64-R and M24M02-DR) on the same bus I2C. Here are the ''device select code'': For M24LR64-R: 1 0 1 0 X 1 1 X In the order: 1 0 1 0 = Device ...
Posted on July 15, 2012 at 12:07Hi, I am using the discovery board (stm32l) using gcc and the gdbserver from Atollic. My program can erase the data eeprom and write some new values in it, However when I start a new debug session the contents seems t...
Posted on July 11, 2012 at 15:39 Hello ALL We have already completed a project with the STM32F It took some time to get up to speed but eventually we did, and completed a complex project. Now we have a project which could work with a s...

Posted on July 11, 2012 at 15:46Hi, I would like to know why in TIM_OCMode_PWM1, I can calculate the frequency 'Duty cicle' TIM_CLK / (TIM_Period + 1) 36MHz/(999+1) Frequencia = -----------------------------...
Posted on July 07, 2012 at 09:02The content of this function is /* Clear the flags */ TIMx->SR = (uint16_t)~TIM_FLAG; But I think it must be in this format: /* Clear the flags */ TIMx->SR &= (uint16_t)~TIM_FLAG; a & is needed for correct clear ...
Posted on July 13, 2012 at 10:56Dear ladies and gentlemen, I am currently writing on my Bachelor thesis about boundary scan and its advantages/ disadvantages. Our company is currently launching the new STM32 micro-controller family and it is my task...
Posted on July 03, 2012 at 13:44Hi, As you can see from the schematic below,the ''C3'' capacitor is a low voltage 1.5F supercap that I use as backup battery to keep the mcu up during the stand-by mode. My problem is that,while I flash the program me...
