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...

one project to produce two bins

Hello, im running on git master branch ESP-IDF v4.2-dev-1660-g7d7521367 I have a little POC to play with a lora library. There is two C files : sender.c and receiver.c I would like to be able to produce 2 bin files : sender.bin and receiver.bin from the same project and same build. Is it possible ? ...

rmt dual way witn esp32-arduino

Hello everyone, Im trying to write a flight controller firmware for quadcopter. I succeeded to send dshot600 commands to esc and make the motor spin. Now i would like to setup dual way communication to get esc telemetry using dshot. Is it possible with the arduino framework to use rmt in dual way fo...
