My ULP example projects will not find esp32s3/ulp.h nor ulp_main.h
Referring to https://registry.platformio.org/tools/platformio/toolchain-esp32ulp/installation,
I tried the “depend on it” approach to include the ulp toolchain. However in platformio.ini the following is not accepted. Error message is “parsing error”
platform_packages=
platformio/toolchain-esp32ulp@^1.23500.220830
and checked that it was installed:
PS C:\Users\owner\Documents\PlatformIO\Projects\ULP2> pio pkg install --global --tool “platformio/toolchain-esp32ulp@^1.23500.220830”
Tool Manager: toolchain-esp32ulp@1.23500.220830 is already installed
Any clues here… going on three days of trying to run the ULP example code…
THANKS!
my full platformio.ini is below:
[platformio]
src_dir = main
[env:esp32-s3]
platform = espressif32
framework = espidf
board = esp32-s3-devkitc-1
platform_packages=
platformio/toolchain-esp32ulp@^1.23500.220830
