Posted on May 31, 2017 at 14:09I'm looking for a count mode in a stm32 controller that counts up and down, depending on a input signal which is low or high. I have seen this mode in a Renesas Controller (RX210), it is called: Phase Counting mode 2....
Posted on May 31, 2017 at 14:06I'm capturing sound through an external microphone and converting it to digital with ADC. I pass the data over DMA and when initializing the audio codec, it runs into a hardfault error.
Posted on May 31, 2017 at 08:24I want to design a TSC board in EMC environment, I designed one before, but it works badly, can any body help me to design a better pcb, power supply and ....?
Posted on May 30, 2017 at 18:56Hi All,I've got a Nucleo-F103RB, and have been able to successfully implement an SPI interface to an FPGA, using the software to control the flow of the SPI.I want to now move this across to the DMA, such that the DMA...
Posted on March 31, 2017 at 15:06Hi, I have a STM32L071KB Chip Inserted in a STM32F031K6-Nucleo Development Board. I am trying to Get into I2C Bootloader mode by Setting BOOT0 Pin to HIGH. But When I Try to detect the I2C Slave Address (0x42)...
Posted on May 30, 2017 at 10:07 hi everybody I'm using stm32l151 and I want to use usb peripheral in cdc mode. I used stm32 cubeMx to generate the project. when I connect the boar to PC, I can see the VCP in device manager.however I can't s...
Posted on April 26, 2017 at 13:41Hi Everyone,I want to measure the pulse width of a square wave signal and thought about using input capture mode and enable interrupt on both edges (rising and falling) and then in the interrupt routine i will read t...
