Project update 12 of 12
Hi everyone, let’s jump straight in with the update content.
Firstly, the Eurorack modules are now shipping from Crowd Supply’s distribution partner, Mouser. You should receive your module very soon, if you haven’t already. Both the Original and Strawberry Edition modules shipped with a SNES reverb emulator patch with OTA functionality for module updates. Here is a quick video of the shipped firmware:
Audio input is from Mutable Instruments Rings with CV control of the reverb time and feedback parameters from the Make Noise Function module.
You can find the binary files for the firmware here. Note the binaries for the different editions have different memory configurations in ESP-IDF menuconfig, so the binaries for the Strawberry Edition boards won’t run on the Original Edition boards, and vice versa.
A few notes on updating the firmware:
Other recent additions to the repository include a setup example for ESP-IDF v5 contributed by project backer David, thanks David!
Earlier this month project backer Robert had some issues with uploading code and after some troubleshooting was able to resolve his issue and upload code to Arduino IDE using the following steps, which may be helpful to other Apple M1 users, thanks Robert!;
Downloaded and installed SL USB drivers from https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
Found this thread about the RTS/DTR timing issue with the M1: https://github.com/espressif/esptool/issues/712
Which led to this patch for esptool.py: https://github.com/256dpi/esptool/tree/dtr-rts-fix
Downloaded this repo branch as a zip file and unzipped it in a sandbox directory rather than trying to install it
In the sandbox directory ran the following:
% python esptool.py —port /dev/cu.SLAB_USBtoUART write_flash —flash_freq 40m —flash_mode dio —flash_size 4MB 0x10000 /PathToMyDSPcode/MyDSPcode.bin
Finally, thanks again to everyone who’s been in touch over the last couple of months, contributing code to this project and troubleshooting some issues, as one of you suggested somewhere to hang out and talk about and get help with projects, discuss ideas, share code and so on would be nice, so, we’ve set up a PÚCA Dev Community server on Discord!
Here’s an invite link to the server, it’s valid for 7 days so jump on it quickly and hopefully chat to you over there soon - https://discord.gg/E2Rm86yG. If you haven’t used Discord before, you’ll need to make a user account here first, and then after you are logged in you can join different servers.
