Posted on February 07, 2014 at 11:33 Hi Everybody, I have a problem understanding the capture compare functionality. I want to use channel1 to fire an interrupt if a match between CCR and counter is detected. In this case, CCR1 is set to ...
Posted on February 01, 2014 at 04:30Hi All anybody can help me I need a motor control sample code using PWM in stm32f4 . I think you are too good in that, I need a sample code in which I can drive a motor , whose step angle is 1.8 degree just a sa...
Posted on February 06, 2014 at 12:08Hi, I like to have a millisecond interrupt. I normally use one of the timer to create millisecond interrupt. But is there any advantage of using SysTick for millisecond interrupt? What is SysTick? Thank you John ...
Posted on January 29, 2014 at 07:37Hi Clive, Can you refered me any example where I can get code for SPI in master mode with DMA. I got example with polling method ot with interrupt
Posted on February 05, 2014 at 16:18 Hello everyone, I have looked for the answer on the internet but I have found no answer so far. Would you know if it is possible to command a transceiver MAX2830 with the STM32f429 ? http://datasheets.ma...
Posted on February 06, 2014 at 08:36G'day, I am working with the STM32F205 and despite having carefully read the ADC chapter in the Family Reference Manual (RM0033) I seem to be missing something... Page 231 of RM0033 Rev 5 says that the SCAN bit ...
Posted on February 06, 2014 at 19:13I am trying to understand the NVIC on a SMT32F407. I have found that we are missing USB interrupts randomly. Since I cant solder a pullup to fix the problem I am stuck. I can understand the documentation enough to...
Posted on February 05, 2014 at 19:19Using an STM32F407, can you have a pin set up as an output and tristated?The reason that I ask is b/c my circuit is acting like it is doing just that. With my pin configuration as follows:GPIO_InitStructure.GPIO_M...
Posted on February 06, 2014 at 07:46I wrote a code to generate rising edge interrupts for a 4MHz clock input to the board. The 4MHz input is generated by MCO while the core is pushed to 168MHz. I found that certain interrupts are not being tacked at...
Posted on February 05, 2014 at 17:20I have looked at using the STM32F427 to drive a 32 bit Universal Bus, similar to VME. I need CAN, SPI, USB etc, therefore the STM32 looks a good choice. I am finding difficulty in getting information on the FMC bu...
