Analog value triggers R2 L2
Problem
Hello! I’m making ps4 compatible controller Using base Raspberry Pi Pico Firmware: GP2040-CE_0.7.10_Pico.uf2 It requires only 1 analog sitck axis and 2 analog triggers, so 3 available ADC pins should be enough, but binding R2/L2 to pins 26/27/28 works only like digital buttons(0/1). ADC pins are fine- tested with Analog stick add-on.
Solution
Is it possible to read analog values for R2/L2? Maybe I should just use different firmware version, in which such feature enabled? Which one will be suitable?
Thank you in advance!
Currently, our Analog addon only supports dual analog sticks via pins 26-29 on the RP2040. With the Pico, since 29 is used by the board itself, you can only use 26-28, as you mentioned, but other boards exist where all four pins are available. However, in order to get full analog compatibility, you will need to use one of the addons that interfaces with a dedicated analog chip. The ADS1256 will support dual analogs plus L2/R2 analog values.
