Posted on September 28, 2012 at 19:08Dear colleagues, are there any stable libraries for IIR (recursive) filters for the STM32F4x, aside of the CMSIS DSP software library? The CMSIS has only lattice (arm_iir_lattice***) or biquad (arm_biqua...
Posted on September 27, 2012 at 18:12.... substituted a 64 pin for a 100 pin f105 and 'forgot' to put a pull-up on a pin for me to 'see' which model. Of course, they built a lot of them before I found out. unfortunately there are no useable PD or PE...
Posted on September 24, 2012 at 15:46Hi, I'm migrating from 8-bit AVR to STM32. I have purchased already a STM3220G-EVAL board with STM32F207 CPU. The first task I want to accomplish is to get a ''Hello World'' application running on this board via ...
Posted on September 12, 2012 at 08:21Hi all,I am using an STM32F103ZG with the STM32F10x_StdPeriph Library. I started the development of the project with Keil ARM-MDK but now moved over to GCC.The switch over has gone pretty smooth until now. I use ...
Posted on September 18, 2012 at 09:16Hi everybody. I'm trying to display a bmp on 3,2'' TFT by using FSMC and stm32f4 graphic drivers. I've done writing some texts changing backcolour drawing pixels but when I want to draw or drive a bmp file with L...
Posted on September 27, 2012 at 11:21I am using STM32F405 in an application and in order to start working with the PWM module I have to check that I read a 100% duty cycle on one channel input. I've been reading documentation, but it seems that inp...
Posted on September 25, 2012 at 04:22Hello All, Finally got to a stm32 discovery specific question. I've turned my baud up to a really high rate 921600. I have a simple loop that sends a request for data and then gets data back from the stm32 as f...
Posted on September 27, 2012 at 15:27Should I be checking for buffer overflows? Do I just clear the bit if the interrupt occurs? What is the best way to handle buffer overflows?
Posted on September 20, 2012 at 16:53I've recently switched to using an ST microcontroller and am in need of some assistance getting FatFS to work. I've never worked with FatFS before but it seems to be the go-to module for implementing the Fat file...
Posted on September 27, 2012 at 18:35Does anybody know if the 96bit unique-ID has different fields? There's no much info about this unique ID (in the reference manual it is said that it has 96bits but after that, when the register is shown only the ...
