IWDG short period (125 us) problem

Posted on February 23, 2017 at 13:04Hello,We are developing a PV converter and we have choose an STM32F407VGT microcontroller in order to controlling its power electronics and communications. We are using the ♯ in order to ensuring that the software...

STM32F0xx findings

Posted on November 14, 2016 at 22:07In a new project there are several identical STM32F031 devices in a role of a slave mcu, driving LEDs and reading in various input signals. As their functionality is very similar, it is tempting to have only one s...

Interleaved ADC

Posted on February 23, 2017 at 00:04Device: STM32F437I am using ADC3 channels 5 (rank 1) and 8 (rank 2) in interleaved mode, the input for channel 5 is 0 volts and the input for channel 8 is near upper limit. Trapping after the first interrupt the 3...
