STM32f4 Discovery - how many ADCs usable?

Posted on August 16, 2013 at 15:59Hello, I understand the STM32f407-VG chip used on the Discovery board has 16 available ADC channels - how many are actually accessible on the board? Some of the ports seem to be assigned to e.g. the MEMS sensor, mic...

capturing PDM without I2S on STM32F103x

Posted on August 16, 2013 at 10:18I have a medium density STM32F103TB, it does not have dedicated sound bus  / I2S. What is a proper way then for me to capture PDM signal, better than reading bit by bit in the ISR at my PDM clocking rate?

STM3220G-EVAL and LIS302DL

Posted on March 05, 2013 at 22:57Hi, I just got a STM3220G-EVAL board. I have to connect an I2C device, but first of all I'm trying to access via I2C the LIS302DL accelerometer on board. Unfortunately, I can't find any example for that embedded devi...

STM32F0 How to reset SPI interface?

Posted on August 15, 2013 at 16:36Hi, I've a problem with the SP interface. If I reset continously the uC (maybe interrupting the SPI communication would do the same) sometimes the receive buffer gets a 4-bit offset. I do communicate with 8-bit valu...
