core and version identification

is there a preprocessor define or a #define tag which i can tell between the cores (e.g. between official & libmaple) and version? i think there is ARDUINO define, but i'd guess that's for the original Arduino? it is a little unfortunate as APIs (e.g. SPI) between cores are at least a little dif...

Re: program modification

i've not worked with SSD1306 but the Adafruit tutorial may be useful https://learn.adafruit.com/monochrome-oled-breakouts/overview there is a datasheet in the downloads page, keep it handy but u'd need to find out if the lcd is responding over the i2c bus i2c has an ack response, one of those ways i...

Re: No one even mentioned the new Raspberry Pi Pico?

it seemed one of the main 'os' are the likes of micro python etc https://www.raspberrypi.org/documentation/pico/getting-started/ that could possibly make it 'less intimidating' for beginners than messing with c/c++ as it is interpreted. e.g. blinking the led may be as simple as typing commands and h...

Re: Examples

either git clone the repository or download the zip https://github.com/rogerclarkmelbourne/Arduino_STM32 then look inside the folder Arduino_STM32/STM32F1/libraries/A_STM32_Examples/ https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/STM32F1/libraries/A_STM32_Examples it may not be on ...

Re: LCD

a little update to my 'optimised' version Adafruit GFX calls fillRect() to draw those blocky fonts. However, as i filled my line buffer with 320 pixels (1 row) of data, this makes it slower when drawing the fonts. Hence i've edited codes in fillRect() to fill the line buffer with the actual pixels n...

Re: No one even mentioned the new Raspberry Pi Pico?

I dont get it... they released a double core.. but no float arithmic support? So it cannt do anything fancy like signal processing. What's the point ? it'd seem to cater to the segment who wanted more gpios and analog (adc) on the soc. it is still a pretty big segment. after all things like stm32f1...

Re: LCD

ok after struggling much with the copy of Adafruit_ILI9341_STM lib from roger's core here is an 'optimised' version. the codes didn't work 'out-of-box' i get scrambled screens etc from the beginning. After working though it this is the result, youtube: https://youtu.be/XAkh2IPh1lw it is fast enough ...

Re: LCD

now i'm struggling with a copy of that ('optimised') ili9341 from roger's (libmaple) core while working along i found i need to patch up codes, instead of Adafruit_GFX_AS, i made it reference Adafruit_GFX directly while it builds, now i get a scrambled screen :lol: there are possibly various improve...

Re: No one even mentioned the new Raspberry Pi Pico?

my guess is a 'duino' would be ported to it, arduino/wiring platform is simply too popular :lol:
