Posted on June 28, 2014 at 17:27Hi, I have configured I2C2 in stm32f215 like below mentioned code, as well as i tried to read the device id. But while i am running its hanging in while(!I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTE...
Posted on June 25, 2014 at 09:49Hi,I had a look at DoFullPID and DoPID functions in PID_C_stm32.c file and undrstood that variables like Error and Output are defined as uint16_t.I'm wondering how these variables deal with negative values? What if in...
Posted on June 30, 2014 at 05:25 I am using a STM32L151 as an SPI slave - the master is another ARM processor. Every 50ms, the master drives NSS low, clocks 250 bytes and then sets NSS high again. On the STM32, I am using DMA to ...
Posted on June 24, 2014 at 22:52I've started trying to use software floating point with the STM32F205. I'm sure this has to do with the Yagarto/GCC toolchain, but I'm hoping someone can give me some ideas as to what might be going wrong. At this poi...
Posted on June 29, 2014 at 10:04 hi guys i have discovery board (stm32f407) and in my code i have some tasks which have to execute in specific time . so i have to have a accuratedelay , i used to use this : void Delay(__IO uint32_t nC...
Posted on June 28, 2014 at 10:46I define a macrio in .h file using C language:#define VERSION 0x01.But I want to use it in an ASM file. How can I reference it? I try to #include ''*.h'', but it failed.
Posted on August 03, 2011 at 13:50Hello -- We're having difficulity getting USART1 and USART2 interrupts to work. We can successfully transmit from either USART but can not receive on either USART via interrupt notification. Polling the USART for ...
