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 ...
Posted on March 11, 2016 at 02:42Hi All, I have two STM32F407 discovery boards. A version B2 board and a new version D1 board. The B1 starts on external power just fine with the same code but the D1 board does not. It only starts up after I connect ...
Posted on March 12, 2016 at 07:47hi i am able to send/rec udp/tcp-ip packets on my stm32F4 via LWIP library and aid of cubeMX.i can see and track the transmitted packets from the STM32 board to pc (via wireshark) now i need to send some raw Ethernet...
Posted on December 15, 2015 at 01:42Hello, I want to use SPI to create a NRZ Style pattern. Everything is ok, except that I need MOSI to be low in between transmissions. Currently MOSI goes high after last byte shiftet out. I created a CubeMx projec...
Posted on March 11, 2016 at 17:20I'm using SPI in bidirectional 8 bit master mode to send 4 bytes to/from my control panel using HAL_SPI_TransmitReceive_IT(). When using SPI_BAUDRATEPRESCALER_256 it works fine, but smaller values cause the module to...
