Posted on May 17, 2011 at 15:12Hi EtaPhi. There should be no diode as its design to be FT which is above VDD, and yea maybe my only solution is the number 1 in which, the FT of the MCU would be useless.. ;( Thank you
Posted on May 17, 2011 at 15:12 Hi EtaPhi.. As the application note says, it should be ok if it was an FT pins, in which STM8L152 I2C pins are FT. My problem now is that, when that 5V device connected to my 3.3V unit by I2C, my ADC pins measure...
Posted on May 17, 2011 at 15:12Hi, can you explain more on ''resistive partitor''....and yes your understanding is correct, my STM8 drive on 3.3V while a 5V device is connected by I2C [FT pins] device, i didnot use a level converter because I was th...
Posted on May 17, 2011 at 15:11 Hi. if we refer to datasheet and notes. 55 AA should work, but for now I have same problem. maybe you can try a new IC as by default bootloader is enable. also ROP should be disable. leo
Posted on May 17, 2011 at 15:11Hi MCU Lüfter on standalone mode, I mean on my custom PCB. Oh I never even tried debug mode. also im using RST pin sa GPIO, maybe it would have some effect. leo
