A Raspberry PI pico killer ?

For friends of AVR, despite of the fact that it is much more expensive :

It could be... but, the AVR NANOs (and, there are many of them) all have the same issue at the moment from a Great Cow BASIC there is no documented register or register.bit list published. So, we have some nice chip/boards and a total lack of documentation.

It will not be a PICO killer if you have to use MPLAB-X and the new MCC to make it work!

One day. I will have to figure how the register.bit work. From the datasheet.

In order to address registers in the supplied C header files, the following rules apply:

1. A register is identified by <peripheral_instance_name>.<register_name>, e.g., CPU.SREG, USART2.CTRLA, or PORTB.DIR.

2. The peripheral name is given in the “Peripheral Address Map” in the “Peripherals and Architecture” section.

3. <peripheral_instance_name> is obtained by substituting any n or x in the peripheral name with the correct instance identifier.

4. When assigning a predefined value to a peripheral register, the value is constructed following the rule:
<peripheral_name>_<bit_field_name>_<bit_field_value>_gc
<peripheral_name> is <peripheral_instance_name>, but remove any instance identifier.
<bit_field_value> can be found in the “Name” column in the tables in the Register Description sections
describing the bit fields of the peripheral registers.

Example

// EVSYS channel 0 is driven by TCB3 OVF event
EVSYS.CHANNEL0 = EVSYS_CHANNEL0_TCB3_OVF_gc;
// USART0 RXMODE uses Double Transmission Speed
USART0.CTRLB = USART_RXMODE_CLK2X_gc;

Oh joy. The fun of new products from Microchip

Atmel Studio is free. And maybe this can help : page 62 of the datasheet.
At least it works up to 5.5 V !

And, all the new PICs work to 5v5.

Re Page 62... that is the Peripheral Address Map and not the register map.

Take PORTA @ 0x0400 this is now a configuration and not the register. So, to make this work would be a total rewrite of the compiler. However, it does not take a genius to workout that PORTA is a mask that the PIC-AS compiler uses to set a register - the smart part is working out the relationship of these masks to registers. A job for the future I think.

The rpipico is interesting, I have 3 but the only way to program them for me is micropython or mmbasic. I am too stupid to use mplab, that's why I use gcb.
I would recommend rpipico with mmbasic ie picomite for anyone interested in microcontrollers but who can only program in basic, just for the price.
There's a mmbasic that is for vga and ps2 keyboard but not sure the point except vga lcd monitors are £5 in charity shops and it's a dual core thing and one core does the basic and the other the vga and it has screen buffers and sprites and some sound, all 80's but better.
