Posted on August 03, 2013 at 13:42Hello , I have a more theoretical question ( for now ) , suppose i want to update the firmware on the STM32 , lets say i put the new FW file on the SD-card , the current FW should detect it and do the update . How...
Posted on July 25, 2013 at 08:40I need to setup the ADC -> DMA to transfer at exactly 44100 hz. (Audio quality)I have setup the DMA -> DAC by setting the clock to TIM_Period to 1088 (48Mhz / 1088 = 44117) But i dont seem to have this control over th...
Posted on August 02, 2013 at 19:18I have the PORT board , with STM32F207ZG , I have written my own SD library , since i did not feel good using the built in library , ...... the library i wrote is working correctly as it should be , and i wrote n re...
Posted on August 03, 2013 at 10:15hi every one,I'm new to STM microcontrollers and i've recently bought an STM32F3 Discovery board.now i'm going to use it to communicate with the in built compass sensor through its I2C interface. using its I2C firmw...
Posted on August 02, 2013 at 22:54Hi to Alli'm trying to get to work the ethernet periphery in MCU, i can successfully init DP83848i , can read regiter, and even(i think) receive packets, but mcu does not transmit any packets outside. the code i've ...
Posted on July 27, 2013 at 17:42 Hi all, I am writing here because I am experiencing problems running the STM32F4 discovery board on a Linux distribution (Slackware 0). Precisely, it seems there is some problem with the communica...
Posted on August 01, 2013 at 16:01dear all,I trust you are well. I cannot figure this out and I was hoping someone more experienced than me could help me out...I am trying to allocate memory for 2 buffers (of uint16_t type) on a STM32F407ZG. each bu...
Posted on August 01, 2013 at 17:00I have a custom bootloader that I flash to the first sector (0x8000000) and when it receives a new program it loads it to 0x8004000. however when It jumps to the program it seems to have problems with a lot of the p...
Posted on August 01, 2013 at 13:52Hi, I have tried to measure the real output voltage on 5V pins so I'd know for sure I won't burn my servo, but after doing so all LEDs went of, nothing happens after connecting board to USB and now on the 5v pin I h...
Posted on July 31, 2013 at 09:26Hi,I am trying to use internal temperature sensor of STM32VLDiscovery board but I have a little problem. I get ADC conversion result and apply the formula in RM0008, temp = (V25-Vsense)/Avg_slope+25, to calculate temp...
