IMHO the timing figures for the example WS2812 LEDs are not correct. Figure 4 on PDF page 38 states that T1 spans 4 cycles but T1 is defined as having...
Some documentation about how heap memory is managed here would be useful. Like, what algorithm etc. I'm mostly interested in a way to check memory stats (used/available) but I can't...
It's not exactly specified in docs if htere's one CRC unit for all DMA channels or there's one per channel. From datasheet it seems there's one per channel but from...
Hey folks! There seems to be a typo in the Pico C/C++ SDK document ([link here](https://rptl.io/pico-c-sdk)): "One you have your FPGA you will still need some [...]" == should be...
I started a thread in the Pico/General forum in which this subject is discussed in detail: https://forums.raspberrypi.com/viewtopic.php?p=2014571 The RP2040 datasheet and SDK doc say that the DMA sniffer computes CRC-32...
There is CLOCKS_CLK_SYS_CTRL_AUXSRC_VALUE_ROSC_CLKSRC instead of CLOCKS_CLK_SYS_CTRL_AUXSRC_VALUE_XOSC_CLKSRC where it suppose to be (it looks like that at least): Examples >Clock example > Auxiliary Clock Sources > XOSC / clk_sys.
While working with the manual on my own build environment I noticed, that essential information is lacking and some things plain wrong. I recorded these for some time. Here they...
We have some fairly complicated timing code, and while we did get things working in the current SDK, this feature would have made it a lot easier to do. Essentially,...
In Connecting to the Internet with Raspberry Pi Pico W section 3.8.2. (HTTP with urequests) the note "HTTPS works, but you should be aware that SSL verification is currently disabled."...
We can have two programs that exceed 32 instructions, as long as they are not loaded by pio_add_program. ``` .program test1 ;20 instruction .program test2 ;20 instruction ``` When we...
