Posted on December 26, 2012 at 10:24I'm working on a project where power saving is a critical issue and I need some help with the power mode (sleep).Here is a short description of the project structure:Main goals:Save an image form the camera each s...
Posted on December 20, 2012 at 11:09I get a problem when using I2S3 of STM32F107. when I2S3 works at slave mode, the MCLK can not be created. What I want to ask is why there is no MCLK output, when I2S3 working at slave mode. Or maybe the I2S3 confi...
Posted on December 24, 2012 at 04:29hi,how can I use the STM32 built-in temperature sensor? the STLM20_ReadTemp() function stops the program and I really need to get this to work.thanks #stm32 #stlm20
Posted on December 23, 2012 at 23:00This problem has me stumped for the past three days. Before I get into the problem I have a few questions. When I look at the memory maps, are addresses, eg. 0x0800 0000, in byte format or word format? I am using...
Posted on December 23, 2012 at 10:30Hello.I try to put a 32 bit word in the FLASH section which need to get know value at programming and during the program it can be modify. In this way I can know next time I power up that this varible has beed upd...
Posted on November 06, 2012 at 19:39Hi: I am using an an STM32F217, and have some difficulty understanding the behaviour of the ADC peripheral. I want to set up ADC1 on pin PA7 to convert on-demand i.e. would like to poll the ADC pin when I want to,...
Posted on December 23, 2012 at 07:53Hi, I know that the STM32 program size is limited to 1024 Kbytes (on flash) or 128 Kbytes on RAM , is there any way to increase this ? maybe to download the program to some other place like EEPROM ? Thanks Michael
Posted on December 22, 2012 at 22:38Hello,I am aware that this question is not directly ST related and might lack details, but I'd appreciate your input.Using STM32F4* device I'd to achieve the following tasks: File management (on SDCard) FTP ...
Posted on December 22, 2012 at 19:12Hi, I just added backup battery to the F407 discovery board. All seem to work ok, the RTC counts while the CPU is on and in Stop mode as well. But if i remove the power all together the last RTC value is preserved...
Posted on December 20, 2012 at 21:50I have a number of switches which generate interrupts. When I Flick switch A it goes from High to Low and the A interrupt occurs(EXTI_PR is now 0x00000200 as expected). I then clear the pending register (EXTI_PR ...
