there’s gonna be two parts of this devlog: the hardware and software.

regarding the software, i just ran the draw_rect_filled function from my draw_functions.h header that i worked on yesterday and alternated the colors (see the gif)

hardware is where everything started to fall apart. the good news is that the esp32 s3 works fine: no shorts, no errors when plugging it in. the main issues are the screen and the speaker.

the screen is a cheap one i got off of aliexpress. it had an unusual pinout, or at least not the standard miso, mosi, etc that im used to. for anyone curious, it’s an i80 parallel spi interface. the pinout can be found here

for the audio module, i already know that’s not gonna work. it was only during my debugging session last night that i realized this: GPIO37 is reserved for PSRAM, and i connected my audio module to pins GPIO35-39.

what this means for future revisions: revision 2.2 is going to be a debugging board. there’s going to be a through hole for every component’s pins so i can cut traces and wire to another gpio/pin if i wanted to. that’s what i did with mallow rev 1.4.

im going to start mallow revision 2.2 tonight!

edit: the gif didnt work, just take my word for it 😭
