Variable frequency pulse train for pulse transformer application
Posted on August 22, 2012 at 17:22Hi The objective is to create a variable frequency pulse train with as little CPU intervention as possible. This was quite straightforward with the TMS320 TI MCU. It had a feature called ''PWM chopper'' where it was...
CubeMx LwIP update for F1 series?
Posted on June 21, 2017 at 11:14Hello,im working with the STM3210-C Eval board (F107VC microcontroller). I recognized that for F1 series there is in CubeMx (ver.4.21.0) only a LwIp version 1.4.1 available while for F4 series there is version 2.0.0 i...
