Posted on March 31, 2018 at 19:35I'm using an STM32F0 in a high volume low power project running on a LIR2032 that can be charged via USB. The STM is specd at 2.4 - 3.6V, with 4.0V as the absolute maximum. When the battery is fully charged however t...
Posted on April 01, 2018 at 19:13Hello, First of all, I am sorry for my english. Then I am doing a application with CANBUS Protochol. so ı need to use PB13 pin of STM32F429. but when I use this pin, CAN2 is not work. When I look datasheet, this pin...

Posted on March 31, 2018 at 22:59Hi guys!I use HAL drivers and I would like to measure the duty cycle of 10 x 25 kHz (asynchronus) PWM signal, but I'm not sure which peripheral should I use:- if I use timer with capture mode then I get 2 x 10 x 2500...
Posted on April 01, 2018 at 15:36Hey guys,I am trying to receive the nmea sentences from my gps module. I am putting the received bytes in an array and if I get the '\n' I want to transmit the array. Problem is it only works once, then it stops:http...
Posted on April 01, 2018 at 12:58Hey guys,I used to be able to download my program to my stm32f723 discovery, but for some reason now when I want to flash even the untouched code, which I got by generating the stm32 cube project I always get errors:...
Posted on October 04, 2015 at 15:19 Hi all, Just plunging in again to learn STM32/ARM coding, and have a GPIO issue (on a STM32L100C discovery board): Why does this work... GPIOC->MODER |= (GPIO_MODER_MODER8_0 | GPIO_MODER_M...

Posted on March 31, 2018 at 19:48Hi,I have an STM32L100-DISCO Board. I would like to askI have seen in the circuit diagram that the PA9 and PA10 Pins are connected to the USB to program the STM32L100 MCU. However, when I use the same PA9 and PA10 fo...
Posted on March 31, 2018 at 07:13I want to connect 2 i2c devices of the same type(having same i2c slave address) to my MCU if I want to communicate with those devices which device is responding to master. How should I differentiate those same device...
