Posted on November 12, 2012 at 18:47Greetings - Seek the higher performance (faster downloads) achievable w/J-Link ''SWD'' rather than the ''on-board'' ST-Link. Reviewed the F4 Discovery schematic - does not appear that there is any easy way to ''b...
Posted on November 12, 2012 at 18:41 I want to edit and use the example of EXTI PA3, but it does not work, what am I doing wrong? void Exti_Config(void) { EXTI_InitTypeDef EXTI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; N...

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 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 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...
