Great to see the release of Astrobe for M7. I’ve read the manual and both the software and the M7 look great. The M7 with its higher clock and the larger 512K SRAM is much more modern and capable than the ‘smaller’ M4/M3 chips.
However, I can’t find support for I2C or SPI in the manual - are these working from Oberon please ?
If so, how many i2c and spi buses are supported by the compiler/runtime ?
