Posted on August 05, 2013 at 14:51Hi everbody,I'm using a ST32F205VE. On my board, I'm using the internal watchdog of the microcontroller and an external watchdog (MCP1318T).During normal operation, the �c sends square pulses every 0.5s to the exter...
Posted on July 26, 2013 at 08:00hello i have configure the SPI1 in the stm32F0 for a data acquisition from a sensor. I marked that the processor always enter in the RXNE interrupt despite there is no data in the MISO pin. /* SPI1 Periph clock e...
Posted on December 17, 2012 at 16:00 I'm working with the STM32F407VG chip (both on the STM32F4Discovery board and a custom board) and having trouble with the SPI port chip select in master mode. The following is the minimal code to demonstrate ...
Posted on August 04, 2013 at 10:32Hullo guys , i have my own SD library working fine , but the problem is that i can not detect the card capacity because according to the datasheet (of STM32F2XX) ...... SD cards do not return long responses . so whe...
Posted on August 04, 2013 at 13:51 MCU: Cortex M3, STM32F103VC I am using a DDS to generate a constant sinusoidal wave. I am sampling this wave and the last 160 samples are almost all garbage. No matter if I sample 7000 samples or 360, t...
Posted on July 26, 2012 at 09:09In Manufacturing my own Boards, and with the assistance of Tsuneo, I have found Usb Pinout Backwards. This is after I analyzed the Specs and Schems - which match my Eagle Pcb Files and my Boards. And, I tested this f...

Posted on March 20, 2012 at 22:43Hi all, Wondering if anyone can help me. I've got the example DAC and ADC programs working fine on the discovery board and am now trying to pass the values read in from the ADC to the DAC. Does anyone know how to do ...
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...
