Posted on June 05, 2013 at 15:41I'm looking to order a 32-bit microcontroller to replace my atmega168. Whatever I order needs to have at least 2 quadrature decoders, and it would be great if it had an fpu, but that's not necessary. Also, I'm looki...
Posted on May 16, 2013 at 18:53I have a project where I will need to flash a few hundred chips that are already on boards. I have set up a chain programmer which is controlled by an MCU. basically it is just a chain of sockets for the boards that al...
Posted on June 03, 2013 at 20:11i want to drive a motor for a control of the door following the LDR sensor signal ( open when it feel light and close it when it's darkness)I have an STM32F100RB. please i need your help urgently thanks a lot
Posted on June 04, 2013 at 18:38Good afternoon, I'm a student working on a robotic project using a STM32F3 discovery evaluation board. I read that there are several IO that are 5 volts tolerant among all IOs the board have. The issue is that I can't...

Posted on May 29, 2013 at 15:33Hi,I am trying to make a 0,5 class meter with STM32 and STPM01.I found a software to calibrate the meter that is STSW-IPE005:http://www.st.com/web/en/catalog/tools/PF257783What I wanna know if there is a hardware that ...
Posted on June 04, 2013 at 16:41 Hi everyone and thanks in advance for your help, I'm going a little crazy here. I am trying to configure an SPI2 line, in master mode, to send data from my STM32F407VG to an LCD screen. However, even if I ...
Posted on June 03, 2013 at 17:01I have a timer configured to interface an encoder.Basically what I want to do is to create a trigger event at every encoder pulse, which resets another free running timer's counter value to 0.What I have now, is that ...
Posted on June 04, 2013 at 13:52Hi All,Is it possible to use STM32f4Discovery without powering it’s ST Link section and associated LEDs. External 5V (at P2 pin 3,4) will power up ST Link section and associated LEDs. Is it safe to remove JP1 and a...
Posted on June 04, 2013 at 08:53Which pin is for external clock source of SysTick? (STM32F407VG.) I could not find in documentation. And also, is it possible to internally connect I2S PLL or MCLK to SysTick or any other timer that have interrupts? T...
