Posted on March 25, 2014 at 06:58I have a low pass filter function in my project which calls q15 fir filter. The first statement in the filter function is &sharpinclude ''arm_math.h''. When complie the project, I received following error: .\Obj\tr...
Posted on March 22, 2014 at 10:18My application board has STM32F405RG microcontroller. I tried to use a project came from STM32F4 Discovery Board by just changing the microcontroller from Keil manual ''Project\Select Device for Target 'ST Link Flas...
Posted on March 18, 2014 at 03:12Hello, I am planning on using the SDADC in STM32F37x microcontroller. The data sheets says the sampling frequency is between 500 kHz ~ 6 MHz, depending on the clock signal driving the SDADC. The output data rate is...
Posted on January 19, 2014 at 07:38I recently downloaded the latest STM32F4 Peripheral library, STM32F4xx_DSP_StdPeriph_Lib_V1.3.0. The library contains peripheral driver and CMSIS V3.20 which includes CMSIS-RTOS V1.02. In the CMSIS documentatio...
Posted on January 14, 2014 at 03:19Hello, I am using STM32F4 Discovery board, uVision V5.1.0.0 development environment which comes with CMSIS-RTOS RTX Version 4.74. In the document for this version of CMSIS-RTOS RTX, the following code example is...
Posted on March 25, 2014 at 03:01Thanks clive1. You pointed to the right direction. I created a new project for STM32F405. Then I checked the C/C++ tab of Options. Here is what's different in the ''Compiler control string'' field: Original : -...
Posted on September 17, 2013 at 04:24Hello clive1, Thanks for the tips. I think the problem might have been caused by the settings or hardware of the debugger, or simply becuase the SWV does not have enough bandwidth to handle the data rate that I ...
Posted on September 15, 2013 at 17:00Thanks clive1 for pointing at the right direction. I made the following changes: 1) In file ''stm32f4xx.h'' change #define HSE_VALUE ((uint32_t)25000000) to #define HSE_VALUE ((uint32_t)8000000) 2) In f...
