Best way for preprocessing conditionnal based on arch

Im looking to use lora components with esp32-C3 mcu. Sadly it doesn't compile out of the box because vspi_host doesn't seem to exist on this chipset. So i would like to adapt the library to use a specific spi host depending of the architecture. which general variable is accessible from preprocessor ...

Re: esp32c3 revisions

Any mass market devkit you get at this point should have ECO3 on it. ECO2 and earlier was only given out in sample quantities. I have bought esp32 C3 from mouser. My order was delayed about 5 weeks due to shortages and production, but thats not the point. My order was sent about 6 weeks ago, so not...

Good afternoon, After two months delay, i just received my esp32c3 devkitC 02v1.1 Sadly after trying to flash blink exemple i got this message: E (38) boot_comm: This chip is revision 2 but the application is configured for minimum revision 3.

Re: ESP32-C3 RISC-V Core - ...What i found just in time ...

Any new about which riscv core is it ? Who is the factory for this and where are the datasheet for it ? The ESP32-C3 chip has some minor issues that it is need to iron out, partly because of some silly mistakes. still the testing and sampling can go on, but they have had to do some FIBs (focus ion ...

Re: ESP32-C3 RISC-V Core - ...What i found just in time ...

easy: sending rmt message, and receiving rmt message, from the same pin. Currently, all accessible code is either only receiving nor sending, but not both in the same time. dshot is a pwm protocol, which implement dual way. when the "master" send a dshot data frame, the last bit request for a teleme...

Re: ESP32-C3 RISC-V Core - ...What i found just in time ...

It's a core based on an existing design, but taken in-house and optimized and partially re-written. Details of the core will make it to the technical reference manual, when available. I can tell you that it's a pretty much vanilla RV32IMC core (iirc, could be we also support A); is there anything m...

Re: [HELP] RMT single wire bidirectional communication (dshot telemetry)

Would it be possible to attach two rmt channels to on signal gpio so that one is configured for sending and the other one is configured for receiving. As dshot600 telemetry is very simple : each packet received by ESC with the last bit to 1, requires a telemetry packet answer from the esc on the sam...
