Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : New board on Hackaday.

A very strange board for a very strange language. I once briefly tried Forth but I just couldn't get my head round it. I found Z90 assembler easier at the time.

2 RISC cores, an ARM core and a 8051? very strange...  They should have thrown a Z80 in at least! :)

not quite as strange as you might think. from the CV1800B datasheet:
  Quote  The chip integrates an 8-bit MCU subsystem, which can replace general external MCUs to achieve the goal of saving BOM cost and power consumption.
[...]
The 8051 subsystem is located in a module that is independently powered by the RTC. The subsystem is configured with an 8051, an I2C/UART/SPI NOR/SD controller, a Timer/WDT, interrupt management, and a Mailbox IP. The system software can use the 8051 to manage wake-up conditions and wake up the system while it is in sleep mode, and communicate with external devices through peripheral controllers.


so the 8051 is mostly just there as an I/O processor, and has limited access to small portions of the main RAM (it also looks like it has 8k of private RAM). once you factor out to 8051, the MilkV's chip is in many ways not dissimilar to the RP2350, but faster and with more sophisticated peripherals.


cheers,
