Posted on May 30, 2012 at 10:45I have designed a PCB that has an http://www.st.com/internet/mcu/product/250189.jsp microcontroller. It kind of works, but the micro has a weird power-on/startup problem. Basically, when the power is applied the micro ...
Posted on May 28, 2012 at 12:29Hi, I see on the an3216 ''getting started with the stm32l hardware development'' that there is a strange 10uF (ceramic?? non polarized ??) connected to the vdd. Instead,if I see that on the stm32l discovery schematic t...
Posted on May 28, 2012 at 18:51Why should the App.h file with : /// PORTA[0..15] = Available : RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOA , ENABLE); GPIO_InitStructure.GPIO_Pin = (GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3 | GPIO_Pin...
Posted on May 29, 2012 at 11:52hi, I am using stm3210c-eval and Ride7. in my project i need to write and read from a micro sd card (file.txt). can you help me? thanks .
Posted on May 28, 2012 at 07:28How should multiple interrupt flags be handled in the timer ISRs? 1. Handle all flags at the same time? 2. Handle a single flag? My code originally did #2, but I found sometimes I would get into a state where an interr...
Posted on May 25, 2012 at 18:50Hello, I am working with a STM32100 RBT6 microcontroller. I was working on a firmware and as the souce code grows up a I had the software starts reach the hard falt handler. I loocked for the CFSR register and the IACC...
Posted on May 24, 2012 at 08:52I have lots of experience with the Arduino and the STM32F4 is my first ''real'' step into microcontrollers. I've downloaded all of the PDFs and the firmware from the STM32F4DISCOVERY page. They have been helpful but I'...
Posted on May 24, 2012 at 16:36I use ST Visual Programmer and http://www.st.com/internet/evalboard/product/250863.jsp. During programming I set Read Protection ON. But now I can not erase or reprogramming the chip (STM32F103RB). I can see ''The devi...
Posted on May 25, 2012 at 03:36I'm having some issues with the SPI on the STM32 and I can't seem to figure out what the problem is. I'm having issues on both the TX and RX directions. I'm using it in master mode in both cases. I have multiple devi...
Posted on May 23, 2012 at 11:52Hi, I am trying to use the OLIMEX STM32-P103 (ARM cortex M3) as SPI master to get some information from an accelerometer but, I dont know how to use SPI. Even after many hours of searching on the internet i did not fou...
