IWDG waking up STM32 from sleep mode

Posted on October 27, 2015 at 13:33I have implemented IWDG and when entering sleep mode IWDG wakes up STM and resets the device. Can i disable IWDG and how?

How to do FFT on audio data after get it from I2S ?

Posted on August 29, 2017 at 03:30Hello all developers,I want to do FFT on audio data from a external device, which have i2s output and analog output. I can sample the analog data by ADC and do FFT on it. Can I do it directly on the i2s data ?Thanks

Unable to enter boot loader mode on STM32F103C8T6: Transmit pin remains as input

Posted on August 23, 2017 at 23:58We're trying to activate boot loader mode on an STM32F103C8T6.We have an outside device drive the BOOT0 pin HIGH before we apply power. Then, we send the initial 0x7F byte to the STM at 115200 bps, 8 data bits, eve...
