Posted on April 25, 2012 at 10:39I am new to and using the Stm3240g Board Firmware. I have a problem with the Ports though. With the Usb and SDCard enabled (nothing else attached), I can Enable Port PA and PB. But when I enable Port PE - then P...
Posted on April 18, 2012 at 07:03I have an obvious question : How do I implement SDCard as MassStorage on the Stm32f4Discovery Board ? Why is there Examples of this for the stm32F103 but not for the stm32F4discovery ? The wonderful 22examples for t...
Posted on April 25, 2012 at 09:01Hello,I have been doing some measurements with the STM3220G eval board using the piece of software at : ./STM32F2xx_StdPeriph_Lib_V1.0.0\Project\STM32F2xx_StdPeriph_Examples\ADC\ADC3_DMAThe ADC reading of the potenti...
Posted on April 22, 2012 at 00:24The EEPROM emulation demo uses Flash pages 2 and 3 (16 Kbyte pages). Flash pages 0 and 1 are also 16 Kbyte pages. WHat happens when your program is longer than 32 K? Is the linker smart enough to skip Flash pages 2...
Posted on April 24, 2012 at 15:57Recently migrate from 8bit MCU to 32bit STM32, I like the FW library, but there is a learning curve required. So I am trying to do a printf with USART, after i compiled the program, i cant receive anything. At this p...
Posted on March 06, 2012 at 13:40Hello, while studying the STM32F4xx datasheet i found the following passage:25.3.1: ''The NSS signal is driven low when the master starts the communication and is kept low until the SPI is disabled.'' This leads me ...
Posted on April 16, 2012 at 22:16Hi all, I am currently using the STM3210C evaluation board and have discovered something which is puzzling, and has to do with the clock frequencies. I am currently using Atollic to program the board and have initia...
Posted on April 21, 2012 at 16:32Hi all, I'm building a custom bootloader and need to provide a way to write protect/unprotect the memory. In order to commit the change, a system reset is required, which I sought to be a software-triggered reset. Fi...
Posted on April 23, 2012 at 21:16It looks to me like the hardware for Tim4 will support PWM input capture on channel 3/4,but when I look at the source code for the standard peripheral library (V3.5.0) the procedureTIM_PWMIConfig appears to be hardw...
Posted on March 16, 2012 at 13:34Hello, I’m trying to force my device (STM32F417) into system memory boot without physically setting the boot pins (cannot access them) and resetting the board i.e. jump to it from my application when the user reque...
