Posted on September 27, 2012 at 11:26Hi, I use the STM32F0 Discovery. I disconnect jump JP2 and connect ammeter. I build a simple program in IAR: int main() { DWORD i; UINT16 j; SystemInit(); SystemCoreClockUpdate(); init_hardware(); ...
Posted on September 29, 2012 at 12:44Hi...... I am trying to understand what is given in the reference design of RF Module based on STM32W108.Here's the link:http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD...
Posted on June 03, 2011 at 23:59Hi, I want to build circuit with STM32F107RC. I projected PCB and chcek all wires with any avaluation kit board. When I turn power on all circuit take about 9 mA. I chcecked all power supply pins aroud microcontroller...
Posted on September 26, 2012 at 14:37Hello all, I am doing a project where the microcontroller (STM32) is sending the parameters to the server via DHCP using wifi module. So, now i want to make available an offline web page to the user where he will...
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...
