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 October 02, 2015 at 04:36I am experiencing a surprising amount of difficulty trying to set up an STM32 VL Discovery board (STMF100RB) with an IDE (IAR EWARM). I have downloaded the STM_STD_Peripherals.zip. and can open examples from it's f...
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...
