Re: EEPROM

Ah, I think the confusion is because the EEPROM program should really be 2 separate programs... The program requires the Operator to select the physical uC model: RB, ZE, RE which is really a technology decision. const char HELP_MSG[] = "Press :\r\n" \ " 0 display configuration\r\n" \ " 1 set confi...

I was using Roger's USB bootloader, and they never failed me.... But now I'm starting questioning the genuineness o...

Re: Having a problem with bootloader after uploading code

The HID patch is not needed for Roger's core, you can select the HID upload in the Arduino IDE. Hi Steve Thanks I've tried many combinations of Roger's core releases and Hid Bootloaders.. If I install the last Roger Core one of the HID bootloader is working, but doesn't reboot the board on the firs...

Re: EEPROM

Hi Mrburnette Thanks for your reply... I've learnt a lot from you, reading your answers in Stm32duinoforum and Arduino..

Re: Having a problem with bootloader after uploading code

Hi Guys Thanks for the help and the hints. stas2z nvic_sys_reset() is working... for the second point I was hoping in a function()… like for the soft reset nvic_sys_reset()… the recompiling and coding solution is a little bit too time consuming in relation to my actual knowledge... as always I like ...
