Re: Float To String - Flash memory consumption

Hi Guys
Pstring is nice and easy to use, but if you have loops that need to be fast...

*** CORRECTION ***

…. I wrote something wrong, it is fast enough … I just forgot a test delay inside a function... Pstring is OK

Many thanks to who wrote this function

I'm going PRO. I built myself a Pick & Place machine

Hi Guys I am an Italian in China... Thanks also to some of you I completed the project in early April... Then I started to produce , but I encountered the usual problem of the self made PCB and soldering... Few months ago I built myself a PICK & PLACE machine ... http://www.picksoeasy.com/images/PSE...

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...

FAKE OR NOT FAKE? Probably fake but good enough

Hi Guys I keep writing here because it is in some way HID- bootloader related... In the past I bought many Blue and Black pills from different Taobao shops... and they always worked... 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: Having a problem with bootloader after uploading code

Hi Guys One small problem... then I promise I will be quiet ;) Roger Clark Core with Hid Bootloader patch... All works great... but If I try to upload a sketch using ST-Link V2 it seems the SWD port is disabled... the only way is to pull up to 3.3 V boot1 then I can upload using ST-Link V2. I tried ...

Re: EEPROM

Hi Mrburnette Thanks for your reply... I've learnt a lot from you, reading your answers in Stm32duinoforum and Arduino.. Yes, I've already checked the library in Roger GitHub... but I was confused, because it seems form the Example Sketch that it is possible to configure the page size.. EEPROM.PageB...

EEPROM

Hi guys I'm using Roger Clark's core... I''m familiarizing with the included EEPROM library... In the beginning was just only dark... but fortunately I found this PDF from ST that clarify a lot, it is " Implementing EEPROM emulation " AN2594 : https://www.st.com/resource/en/application_note/cd001656...
