esp32-c3-supermini - cc1101 v2 hanging on init

[luupux]

Hello, I'm checking to switch from esp32-wroom to esp32-c3-supermini but I went in stuck, I tried different approach then I was not able to understand what I'm doing wrong and I decide to open an issue for help
Mainly the code is in stuck in the init phase,
I already reviewed multiple time the code, wiring and tested the code in two different board an cc1101 so I don't know
what else do

#include <ELECHOUSE_CC1101_SRC_DRV.h>
#include "driver/gpio.h"
#include <SPI.h>

#define PIN_SCK 3
#define PIN_MISO 5
#define PIN_MOSI 6
#define PIN_CS 10

void setup() {
Serial.begin(115200);
delay(500);

Serial.println("🔧 Starting transmitter (v2.5.7)...");
Serial.println("Test SPI");
SPI.begin();
Serial.println("ELECHOUSE_cc1101.setSpiPin");
ELECHOUSE_cc1101.setSpiPin(PIN_SCK, PIN_MISO, PIN_MOSI, PIN_CS);
Serial.println("Test Init");
ELECHOUSE_cc1101.Init();
Serial.println("test secCCMode");
ELECHOUSE_cc1101.setCCMode(1); // set config for internal transmission mode.
ELECHOUSE_cc1101.setModulation(0); // set modulation mode. 0 = 2-FSK, 1 = GFSK, 2 = ASK/OOK, 3 = 4-FSK, 4 = MSK.
ELECHOUSE_cc1101.setMHZ(433.92); // Here you can set your basic frequency. The lib calculates the frequency automatically (default = 433.92).The cc1101 can: 300-348 MHZ, 387-464MHZ and 779-928MHZ. Read More info from datasheet.
ELECHOUSE_cc1101.setSyncMode(2); // Combined sync-word qualifier mode. 0 = No preamble/sync. 1 = 16 sync word bits detected. 2 = 16/16 sync word bits detected. 3 = 30/32 sync word bits detected. 4 = No preamble/sync, carrier-sense above threshold. 5 = 15/16 + carrier-sense above threshold. 6 = 16/16 + carrier-sense above threshold. 7 = 30/32 + carrier-sense above threshold.
ELECHOUSE_cc1101.setCrc(1); // 1 = CRC calculation in TX and CRC check in RX enabled. 0 = CRC disabled for TX and RX.
Serial.println("Rx Mode");
}

void loop(){
Serial.println("amicici");
}

Then this is the output
12:14:38.705 -> 🔧 Starting transmitter (v2.5.7)...
12:14:38.705 ->
12:14:38.705 -> Test SPI
12:14:38.705 ->
12:14:38.705 -> ELECHOUSE_cc1101.setSpiPin
12:14:38.705 ->
12:15:26.217 -> 🔧 Starting transmitter (v2.5.7)...
12:15:26.217 -> Test SPI
12:15:26.217 -> ELECHOUSE_cc1101.setSpiPin
12:15:26.217 -> Test Init

Hey I have the same problem, have found a solution yet ??

Did #160 or #161 fix this?

Did #160 or #161 fix this?

Doesn't look like it - I just wrote a sketch with the same board and radio, and I'm having the same error.
SetSPIPins succeeds (if (ELECHOUSE_cc1101.getCC1101()) { }; returns true), but ELECHOUSE_cc1101.Init(); hangs, then the c3 supermini reboots.

I tried a few different pin configuirations as the C3SuperMini is notoriously annoying with pins, but sadly I got no success.
Tested with multiple boards and radios.

Have it narrowed down to the SpiWriteReg(CC1101_FSCTRL1, 0x06); line.

And then the crash. Unsure why exactly.

[Windyo]

Editing the library to set the SPI.End() before the RegConfig fixes the init.
I'll test to see if the module works correctly.

If you still have some issues you can try my fork https://github.com/Viproz/SmartRC-CC1101-Driver-Lib
I added some timeouts to some while loops which could cause crashes if the CC1101 does not behave exactly as expected. I also merged the fix for the RegConfig issue.
