Posted on October 02, 2015 at 23:18Hi guys, I have a problem. I have a USB-RS232 converter and i'll do usart tutorial with STM32F4. Codes are working, but meaningless character viewing at the serial Hyper terminal program. Baudrate 9600. Clock Confi...
Posted on September 30, 2015 at 15:31I want to pass data from MP45DT02 MEMS mic to the audio DAC CS43l22. All the configurations seems okay, the thing I can't seem to achieve is the correct Fifo buffer. The FIFO read variable (which points to the n...
Posted on September 02, 2015 at 15:20LWIP stack is lockingup about every 48-60 hours, with a casually polling ModbusTCP connection (~ 1000 ms between polls).It requires apower cycle of our equipment to restore the operation of the stack.i use codes ...
Posted on October 03, 2015 at 04:20 Hi, I'm currently working with STM32F105RC chip and trying to use UART4 (PC10 and PC11), which connects to a USB to UART module to a computer. The problem is, I'm not getting any readings from PC using hyperte...
Posted on August 22, 2015 at 07:04I am using an STM32F407 chip on a custom PCB. Using (mostly) HAL libraries, but I've ended up writing a lot of my code and verifying the registers individually. I am using an ADC that communicates over SPI. The tran...
Posted on January 23, 2015 at 11:26having developed with the SPL in the past, and now tried the STMCube i would like to make a couple of observation. - i understand the rational for the development of the STMcube tool, but it is forcing developers d...

Posted on October 02, 2015 at 13:41Hi, I'm trying to understand a Note from Reference Manual page 665. It state: ''The VBUS pin can be freed by disabling the VBUS sensing option. This is done by setting the NOVBUSSENS bit in the OTG_FS_GCCFG registe...
Posted on October 02, 2015 at 15:51 Guys, I tried to send data via SPI and DMA but can not get a proper data sent... I can't see CS up and down as well..... code: void Mp3WriteRegister(unsigned char addressbyte, unsigned c...
Posted on September 19, 2015 at 14:30I need to call several CDC_Transmit_FS, but between them I need to wait to previous CDC_Transmit_FS finish, otherwise I overwrite output buffer.Is there a flag, a macro or something else that may allows me to det...
