STM32F4xx: read out protection level1 results in MCU getting locked and frozen
Posted on September 28, 2012 at 13:59Hello all, I hope I'm just doing something wrong. I programm the chip with ST-Link Utility (v2.3.0 - the newest). At read out protection Level0 the programms runs fine. If I set the protection level to ''1'', the...
Final State of PWM
Posted on February 04, 2013 at 10:17 Hi , I am trying to drive a LED Driver IC with a PWM signal on button press. However , it seems that at the end of a PWM cycle the LED final state is not determinable (maybe on/off). It seem that it...
STM32F0 Discovery JP1 (STLINK USART RX,TX)
Posted on February 05, 2013 at 01:35What is the purpose of JP1? It connects to the STLINK MCU, and via two solder-jumpers on the bottom of the board (SB14,15) to PA9,10 of the 'F051 (the USART-1 pins). Can the STLINK enumerate as a CDC endpoint, a...
STM32F051 USART Not working
Posted on February 01, 2013 at 00:39I created some simple code on the STM32F05-Discovery board to write a byte of data repeatedly out USART1. However when I run this code on my target board the USART doesn't send the data. The TXE line goes low an...
