Posted on November 12, 2012 at 10:27Hi all, I have a pressure sensor whose the impedance is in the range [1400W 3000W]. I would understand and know if the ADC impedance in stm32f1xx devices matches my sensor impedance or not?MCU Lüfter
Posted on November 12, 2012 at 17:17Hi, I've been trying to make the IDD current measure function on the STM32L152D EVB to work in order to measure the current consumption during STOP mode. I think I've finally made it work, but it seems like the cu...
Posted on November 09, 2012 at 11:21Hi, I entered sleep mode with PWR_EnterSleepMode(PWR_Regulator_ON,PWR_SLEEPEntry_WFI) ; but I can return to normal mode, even i push the user button (connected to EXTI0). What's wrong ?
Posted on November 11, 2012 at 23:46Reading UM0033, page 138, figure 14. Sorry, can not exactly understand it. For example, I want to connect C.8 to CAN1_TX and C.9 to CAN1_RX. I see AF9 (CAN1/CAN2, TIM12..14). and need to use GPIOC_AFRH(LSB) GPIO...
Posted on November 12, 2012 at 14:47The STM32L1xx datasheet says that the temp sensor sample time will be between 5 and 10 uSec. The manual confirms this, saying that you should use a 10 uSec sample time. With the ADC clock running at 16MHz, this ...
Posted on November 12, 2012 at 14:40Hello. I try to operate ADC3 triger by TIMe CC1 on scan. TIM3 is working (I test it by use its interrupt). But I can't get EOC interrupt from the ADC3. I check that I operate the RCC for both and also allow NVIC f...
Posted on November 10, 2012 at 15:32Hi, I have always programmed in C + + and Java or C ♯ and now that I start using microcontrollers have a lot of trouble! can you recommend a good Book of C or a good online guide? thanks #learning-c
Posted on November 11, 2012 at 02:08Hello, I am trying to implement a simple USART echo program but am running into communication problems between the discovery board and puTTy. When I transmit a character to the discovery board it does not respond....
Posted on November 11, 2012 at 09:33 Hi everyone, I'm trying to get a accurate reading out of 2 potentiometers but they keep affecting each other. Also when I press my touchpanel (XPT2046) the readout is affected.... Does anyone hav...
Posted on November 10, 2012 at 21:01I'm writing my own USART code to work with USART1. I need to know what the start-up code that keil gives you sets the clock initially at. I can change it manually but id like to know where the code is. Also USART1...
