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 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...
Posted on July 12, 2012 at 16:08 Hi, Hardware -> STM32-Discovery IDE-> Keil uVision getBit(USART2->SR, position) works in the non-interrupt mode, but, it doesn't in the USARTn interrupt mode...! I have linked the USART1's...
Posted on July 12, 2012 at 02:23Using stm32f4 discoveryI am off to a good start with this board. I can not do floating point numbers. That is annoying but ok. I decided to move on and not use floating point numbers. When I try to fixed point I don't...
