i really get crazy with the two stm32 cores (stm32duino core vs maple core).
if i use the maple core i cant use adafruit gfx and adafruit ssd1306
if i use official stm32 core i cant use the usb composite library for getting usbmidi to work
why nothing is really working?
with maple core i also cant get same pwm capable pins work as pwm pins compared to the official core
its ultra frustrating
with the maple core i get tons of errors what conversations cant work in different functions like: no matching function for call to 'SPIClass::transfer(uint8_t&, size_t&)’*
_spi->transfer(buffer, len);*
or invalid conversion from 'const uint8_t {aka const unsigned char*}’ to ‘uint8* {aka unsigned char*}’ [-fpermissive]*
if (_wire->write(prefix_buffer, prefix_len) != prefix_len) {*
this works with taht core but lacks with this function and vice versa
i only want using an i2c oled with the adafruit gfx lib
want to use pwm output on PB8 PB9, PA15, PB3, PB10, PB11
while USBcomposit usb midi interface is appearing over usb and everything in one core
does anyone have same errors, problems and mybe solutions?
I might be wrong, again! But, is the Maple core still being worked on? I was sure I read on their github some time back – when I first got a Blue Pill – that Maple was dead and not to use it.
I had the same problem like in the first post, Adafruit_1306 library problem with different cores, and lost few days going back and forth…
Anyway I solved it. First, I`m using official STM32 core and this library :
Im using 4pin oled display (I2C) and everything works great, btw I dont recommend wasting time using maple core.
