version 2.1.5

What's new in version 2.1.5

• general source code, cmake, and script file cleanup
• add support for picow and vgaboard
• update C example source code
• centralize reset function, not using watchdog
• remove trim command, garbage collection in littlefs is automatic
• move all constant variables to flash, releasing RAM to better use
• expand status command to show memory and screen use.
• clarify and pack exe file header
• delete resize cmd, use clear instead
• improve release_build script (less error prone)
• for RP2350 all floating point operators as well as the sqrtf function use inline FP instructions instead or wrapper calls.
• for RP2350 use inline idiv and mls instructions to implement integer divide and modulus operators instead of wrapper calls
• rp2350 use expanded range of movw immediate to reduce amount of PC relative addressing
• add RP2350 PWM IRQ numbers
• many rp2350 peep hole optimizer opportunities

pshell v2.1.4 (pico+pico2)

What's new in version 2.1.4

• Revert to merged cc_externs and cc_defs
• Update FUNCTIONs documentation
• Add hardware UART function and defines
• Expand heap size to maximum
• RP2350 peep hole addition + misc text diffs
• Improve peep hole optimizer logic

pshell v2.1.3 (pico+pico2)

What's new in version 2.1.3

• Internal compiler restructure, separating functional parts, moving all constants to flash.
• Multiple peep hole optimizer for RP2350 improvements.
• Extend fault handler for RP2350
• Replace sqrtf function call with inline floating point instruction.
• Updated C examples
• Optimize integer compare, and divide

pshell v2.1.2 (Pico, Pico2)

What's new in version 2.1.2

• substitute HW FP sqrt instruction for sqrtf function call. (RP2350)
• a few more peep hole optimizations. (RP2350)

pshell version 2.1.1

What's new in version 2.1.1

• improved peep hole optimizer. Bug fix and RP2350 floating point optimizations.

pshell version 2.1.0

What's new in version 2.1.0

• rp2350 specific peep hole optimizations
• exclude unused code for RP2040 and RP2350, reducing pshell executable size.
• for rp2350 use FP hardware to implement sqrtf function.

version 2.0.3 (Pico2 support)

What's new in version 2.0.3

• Optimize /, -, >, >=, <, <= float operators for RP2350
• Add a few floating point instruction decodes to disassembler
• Default to inline floating point instructions (RP2350). Use -x compiler option to revert to RP2040 style wrapper function calls.

version 2.0.2 with pico & pico2 support

What's new in version 2.0.2

• Add -f compiler option to generate inline floating point operation for RP2350. The default is to generate RP2040 style wrapper function calls.
• Generate integer division sdiv for RP2350.
• Update RP2350 GPIO constants and functions for RP2350.

Version 2.0.1 with pico2 support
