Posted on October 19, 2011 at 16:46I'm playing around with SPI (SPI2 on the VL discovery board), and am able to configure the chip as a master and I see the clock and data outputs. Right now I'm using polling to transmit - interrupts can come later...
Posted on October 17, 2011 at 20:07Hello, I use STM32 for several years, but know I dont know how to solve this problem. When I start my STM32int main(void) { RCC_Configuration(); NVIC_Configuration(); GPIO_Configuration(); ADC_Configuration(); GPIO...
Posted on October 20, 2011 at 11:04Hi, I have tested the CRC generator of the SPI peripheral. But I get some strange result... The message to send is the byte 0x40. I send this message after enabling the CRC8 computation. Then I read the tx CRC. I r...
Posted on October 20, 2011 at 01:57I started having problems with STLink (MDK-ARM - getting an ''Internal Command Error''), and ST Visual Programmer has problems. Log:Hardware configuration set to <ST-LINK on USB with STM32F100xB plugged in and SWD...
Posted on October 06, 2011 at 13:13Hi, I started to modify the CustomHID example of the ST USB Lib V3.3 to get it running on my Olimex STM32-P103 evaluation board. I want to use this firmware to start developing a PC controlled board without the nee...
Posted on October 19, 2011 at 08:16Hi , i am using STM32F100C4 and a 8 Mhz quartz.I want to measure frequencies in range of 48 Hz - 1 Khz on some input pin.What is the easiest way to do that ? ( I am using Keil uVision 4 IDE),is it using timer captu...
Posted on October 19, 2011 at 11:53Hi,Can any please help me out here. I'm trying to set up a timer-interrupt, TIM3, for every second. But when I'm trying to initialize the TIM3 interrupt my system crashes :(I'm running @ 72MHzHere is my code for in...
Posted on October 05, 2011 at 19:18Hello all, I have search through the forums and google for the exact problem I am having to no avail. The issue I am having is regarding finding the filesystem on the SD card, in particular the check_fs function in...
Posted on January 28, 2011 at 10:39 Hello, I try to debug and simulate the discover project on MDK-ARM evaluation IDE. I have no hardware. So i just want to test debug and simulation. Here below the error message after build and start ...
Posted on October 18, 2011 at 03:34The data sheet for the STM32F4 series states that 24 external ADC input channels are available, but I can find only 23 in the pin assignments. ADC3_IN8 appears to be missing. The F4 reference manual (RM0090) descri...
