Posted on May 14, 2014 at 11:54Hello, I've problem with a clock setting for a MCU. There is some points, which describe it. General: MCU: STM32F207IGT6 Clock: HSE 8Mhz -> PLL 96Mhz Using module: ETH MAC - MII 4-bit mode - 25MHz neededFSMC - synchro ...
Posted on May 18, 2014 at 14:10Hi! (Using the STM32F103RBT6 chip) I've configured TIM2 timer as a prescaler for TIM3 (RM0008 page 386). Timer TIM2 is configured for ETR (RM0008 page 365). So what I've got is a 32bit timer counting pulses on PA0 (suc...
Posted on May 16, 2014 at 16:12Hi everyone, i'm trying to enter bootloader from my application, so i could use STM flash loader tool to upgrade software. Everything is working fine and im entering bootloader, but after i flash with flash loader tool...
Posted on May 18, 2014 at 14:46I am using STM205RBT^ & I have noticed that it does not start executing first instruction sometimes. I am using HSI oscillator & used pll to make 120Mhz. My first line in code is to toggle a pin. Only two possibilities...
Posted on April 23, 2014 at 15:33hi all, I'm new in the forum and I am experiencing a problem of ISR , which doesn't happen for TIM12 while, with same ch1 configuration register and same pwm signal input, set the ISR calling for TIM9, as expecte...
