Posted on September 28, 2012 at 09:25Hi all,I need to be able to reprogram an STM32F103 device in the field through a USB connection on UART1. It is critical that the firmware update is performed without any direct user intervention on the board (ap...
Posted on April 20, 2012 at 09:21I have recently assembled 6 PCBs with STM32F407IGT6 micros on them. I seem to be having a problem reading from RAM. This was first noticed when one of the boards was hard faulting and returning a non-precise bus erro...
Posted on September 28, 2012 at 19:28Hello, I've been wondering about upgrading to the STM32 from an ST10. It's imperative that certain thing are as close to instantaneous as possible. I was thinking I've identified two bottlenecks and two soluti...
Posted on September 26, 2012 at 18:20Hello!I'm trying to get an STM32F407 with the LQFP176 Pinout to output in OC PWM1 mode. My code is as follows: /* set up GPIO as timer output GPIOI 5, TIM 8 CH 1*/ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOI...
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...
