Posted on May 26, 2015 at 11:57Hi, I have problem with ADC1 conversions on STM8S-Discovery. I have configured the analogic inputs following: PB4 - AN4 PB5 - AN5 PB6 - AN6 unsigned char ADC_Config_INT ( void ) { GPIO_Init(ADC_PORT,ADC_15V_PIN, GP...
Posted on May 26, 2015 at 13:25I'm trying to get data from Invensense MPU9250 with I2C on SC1 of stm32w108.These are connected each other with 10k ohm register.But it doesn't get data.I coded as below.Please tell me how to fix.void SCinit(){ ...
Posted on May 26, 2015 at 07:11I would like to use the PWM as clock source for other device. so I want to know the maximum frequency of PWM. As faster the frequency of PWM signal increase, the more the shape of PWM signal become to triangle signal. ...
Posted on May 26, 2015 at 09:49Hello,I am debugging step-by-step my project on stm32f103vd, using CooCox CoIDE, and ST-LinkV2.when I enable whatchdog, the system go then to Reset_DefaultHandler(). I think that's normal no ?and how I can debug step-b...
