Posted on December 13, 2011 at 05:47I know this is a really noob question but I'm really new to STM micro controllers and I need some help. So I just bought the STM32 F4 Discovery board and I found a usb A to B connector so I connected it to my comp...
Posted on December 04, 2011 at 23:11Hello. I have troubles with connecting adxl345 to stm32f103vet6.When I try to read a data from device, I always get '0'. For example:int16_vect3 myVec;ADXL_GetACC(myVec);///myVec.x now is '0', myVec.y=0,myVec.z=0I...
Posted on December 06, 2011 at 18:19Hello. I have a device connected to stm32 through I2C1. Am I right initialize it?&sharpdefine DEV_ADDR 0x53uint8_t I2C_ByteRead(uint8_t Addr){ uint8_t tmp; while(I2C_GetFlagStatus(I2CG, I2C_FLAG_BUSY)); // Whil...
Posted on December 09, 2011 at 20:57 I have a Max3107 UART hooked up via the SPI1 bus on a STM32F103ZG. Currently, I can configure the UART, write data out and receive it. I'm trying to implement trigger interrupts because the UART has a 128 word...
Posted on December 12, 2011 at 16:08Hello, I'm using the ST libraries to initialize the IWDG with following code: IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable); IWDG_SetPrescaler(IWDG_Prescaler_128); IWDG_SetReload(0x400); IWDG_ReloadCounter(...
Posted on December 12, 2011 at 13:16Hi, how many USB endpoints are possible with the USB OTG interface?
Posted on November 30, 2011 at 21:04In the User manual UM1467 (Getting started with software and firmware environments for the STM32F4DISCOVERY Kit) on page 4 under 2.1 ''System requirements'' it says: 'USB type A to Micro-B' cable, used to connect...
Posted on December 06, 2011 at 10:12The follow ISR capture an event incoming on TIM4_CCP2, and each 8 of this events the register oldCCP is subtracted from CCR2, this value is strored in loop_buf[cyc][lb_index], the value of CCR2 updates oldCCP, and...
Posted on December 10, 2011 at 06:26Hi, I want to make a library for EAGLE of the STM32F407IGT6 (LQFP176). On Site 142 of 154 in the datasheet, the lqfp176 package has just 144pins, is that correct or a mistake by ST? with regards alex
Posted on December 09, 2011 at 23:23hi,i have a signal to rate at 3mbit/s. The clock and signal are separate on two line.i tried to use connect EXTI on the clock. When i have a interrupt, i read the PIN where the signal's. This solution don't work.S...
