Posted on March 14, 2016 at 11:19Hello there, I have a question regarding output compare mode with 32 bit timers in STM32F4 mcu. I have only one 32 bit timer that is free to use. I need to generate interrupts for 2 events. Those events should occur...
Posted on March 14, 2016 at 10:54Hi everyone, I have some cpu-load issue on my design, so I am trying to redesign an high frequency Rx spi transfer. (24bit) I would like to setup a timer that at a certain frequency triggers the Rx SPI transfer. Righ...
Posted on March 14, 2016 at 11:12Dear All,I am using an stm32F4discovery ( stm324f07vgt) to capture images coming from a camera OV5642, i would like to send pictures ( 5MP) with 3G module, Could you please suggest me an exemple of module that suppo...
Posted on March 11, 2016 at 17:03Dear Community, I am trying to use two peripherals (STM23F373) SDADC1 and DAC1_1 having the same DMA access channel: DMA2_Channel3 (STM32F37x reference page 164). Due to a synch problem I want to use the DMA in norma...
Posted on March 11, 2016 at 20:08Hi to all, I have a big issue with SD cards. I initialize correctly my sd card, but when I try to read a block, I can read it only the first time. This is my routine: ===================== uint32_t MYSD::ReadSector(u...
Posted on March 07, 2016 at 12:56Hi, I have a litte problem. I need to generate a variable frequency (not duty cycle) for a piezo buzzer. Unfortunately the PCB layout is givn as a H-bridge (see image). ''Piezo'' is connected to TIM4_CH1 and ''Piezo2...
Posted on March 11, 2016 at 18:52 I have found a strange behavior of STM32L Low consumption 1.0 uA (as stated in the datasheet) is reached in the first sleeping with the STOP mode after reset but in sleepings that follow the first and next wake-...

Posted on March 11, 2016 at 21:02 Hello! I need an advice. My stm32f103cb chip has ADC with 0.39 us per point conversion rate on one channel. But datasheet says its max rate is 1 Msps (1us). I checked sampling rate with external oscillograph (1 ...
Posted on March 13, 2016 at 01:59 Hello i'm trying to configure an uart 1 or 2 interrupt in sw4STM32 and cube mx, but never responses the interrupt i can recive data from uart and send data in uart 1 and 2 in pooling mode mi code. Main ...
