Posted on June 22, 2011 at 00:03I have three questions regarding clock configuration for the STM32F207 / STM32F217: 1. Is there any advantage to using any specific HSE frequency between 4MHz and 26MHz that is evenly divisible by 2, if the goal is t...
Posted on June 21, 2011 at 15:59it seems stm32L152 is almost pin to pin compatible with stm32f103. I am thinking to replace current design with L152 part. but I did find any ST documents talking about this. does anyone done this? any suggestion or t...
Posted on June 21, 2011 at 18:21Hi, I have to create a firmware using stm32f100 microcontroller. I don't be able to start because the project that i use doesn't function. I need someone that is working, or he has morked whit this micro and with this...
Posted on June 08, 2011 at 16:57Has anyone successfully worked with driving SD card with SDIO_CK over 25MHz? I'm working on a SD card project. I'm trying to increase SDIO_CK up to 48MHz. but I keep receive SD_ERROR 3 ''SD_CMD_RSP_TIMEOUT ''. SD car...
Posted on June 21, 2011 at 09:26hello, I have dowload the example of HOST USB for stm32f105 (same for stm32F107) and when I compile my project (I have copy/paste all files in my project) i go into the inifinite loop of HardFault_Handler(). this happ...
Posted on June 20, 2011 at 14:55i'm implementing a SMBus between stm32f103 (slave) on STM32-SK development board and omap3 (master). I send to slave a write command , but the slave does't start the interrupt I2C1_EV_IRQHandler. Why?? Thank you for y...
Posted on June 20, 2011 at 12:31Hi, Is it neccessary to do something to enable BusFault and MemManage Interrupts, or are these active as per default? I.e. the HardFault interrupt is always enabled, the only thing I need to do is add a HardFault_Han...
Posted on June 17, 2011 at 02:02Hi everyone,I've just ordered the STM3220G-EVAL, but while waiting for it to arrive, I'm looking at pin mapping for my application.In particular I have a couple of questions in regard to USB FS, and JTAG/TRACE.USB FS=...
Posted on June 17, 2011 at 19:25I am running the simplest sample program that came with the Standard Peripheral Library Template (that lights 4 LEDs, displays a line on the UART, and 3 lines on the LCD). Using the Keil tool chain, I turned off Use ...
