Posted on June 10, 2013 at 23:19i used timer2 and it's clock source from APB1 and Prescaler value for APB1 is 4 it's mean's APB1 work at 42mhz ''168mhz/4 '' becuase the maximum frequency is 42mhz for APB1. i searched in internet and so...
Posted on June 10, 2013 at 17:34i have a stm32 discovery kit , and i am sensing the back emf of sensorless motor which is driven by other kit. i am using adc with one channel and a timer. the main aim to calculate the period while reading the adc-...
Posted on June 06, 2013 at 20:48Hello, I've TIM1 set for PWM signal generation (STM32F407VG). Everything works well but I want an interrupt to be rised on the falling edge of pulse and I have no idea how to set it. Currently I've the following sett...
Posted on June 09, 2013 at 16:32Hey Guys, I'm currently playing with the STM32F205RC Controller and I have some troubles with using the A/D converter with DMA. The task I want to do is quite simple. I want to measure a voltage using ADC1 on Port A ...
Posted on June 10, 2013 at 16:30In the user manual for the discovery board, it says that an installation wizard should appear when I connect the board to my computer for the first time, but that didn't happen. I downloaded the driver from here: htt...

Posted on June 07, 2013 at 20:17I need to interface the STM32F407 to a 1K x 8 DPRAM (7C131). The 100 pin STM32F407 package I want to use does not support nonmultiplexed address and data. I have no problem in using a latch to de-multiplex the A0-A7 f...
Posted on August 24, 2012 at 00:41stm32f4-discoveryI am impressed with the built-in 12bit adc. I want eventually to read 12 voltages at 10Hz or greater. I am going to simplify the problem to 2 channel add and expand to 12 once that is working. I rea...
