Posted on March 06, 2014 at 21:52 Hi, i have just bought an stm32f0 discovery board in order to use its real time clock. I follower the instruction in the Rtc file.This is my configuration and the main function. My problem is when i star...
Posted on March 05, 2014 at 23:37Hi all, I'm hoping this is an easy one and just something I am missing. A google didn't return anything obviously relating to my problem. I have some messy code that sets up my USART peripheral correctly. I have used...
Posted on March 06, 2014 at 09:37Hi I still could not understand the operation of the analog watchdog. For example I want to protect a short ciruit in the H-bridge ; so I put the shunt resistor and set the limit of the maximum current ; for exampl...
Posted on March 06, 2014 at 09:55Hi everyone. today I'm newbie in LCD. I discover the LCD LCM DT192x64 but I don't have any ebook or reference manual about that, I already searched on google but I get another. If you have any book relative with my ...
Posted on March 04, 2014 at 23:10 I'm trying to do a pin interrupt (EXTI). My code: // IRQ handler for EXTI0 void EXTI0_IRQHandler ( void ) { EXTI->PR = 1UL << 0; buttonPress = 1; } int main ( void ) { // some system stuff here ... ...
Posted on March 06, 2014 at 11:23Hi you all, I am trying to produce a low jittered sharp clock signal at 96kHz freq. for my I2S application. The purpose is obtaining a interrupt at every 96kHz cycle (10.4us) and with each interrupt, sending one samp...
Posted on March 06, 2014 at 03:14Hi, I use speex encoding with Stm32f407VG microcontrollers follows application note ''Vocoder demonstration using a Speex audio codec on STM32F101xx and STM32F103xx microcontrollers'' but differrent: I use an codec I...
Posted on March 05, 2014 at 22:41Hello, I'd like to measure precisely the time spent in WFI / Sleep mode. Is there a non-too-intrusive way of doing that in software ? Thomas.
Posted on March 05, 2014 at 10:29Hi,I can't use the same timer in IAP code and user application code in the same time, even if I reset all registers and interrupts concerning this timer before jump to user application address. Note that I reallocate...
Posted on March 05, 2014 at 15:31Hi All,I am facing the weird problem. I use STM32F0 discovery kit. I have my setup fully working with debugger integrated in eclipse. At some point, I decided to remap PA11 to AF_1 so that I can use the UART1 with fl...
