esp32-c3-devkitm-1u BMP280 Crash Dump

[jimcondit]

First time using the UncleRus library. While trying to use the example code for the BMP280, and after modifying the SLA and SLC pins (respectively GPIO5, GPIO6), all compiles nicely but throws a crash dump during execution. (Shown below.) If I believe the dump, it appears to be crashing at the bmp280_init call. Also, it appears to be looking for the device at 0x76. But, when using espressif 12c_tools code, it finds the device at 0x77, which appears to be correct from other resource. Did I miss some configuration parameter?

Thanks for your help!

Why it's crashing? It's crashing due to the call ESP_ERROR_CHECK() macro on the line 28 of main.c in example:

ESP_ERROR_CHECK(bmp280_init(&dev, &params));

bmp280_init() tries to communicate with the device by incorrect I2C address, returns ESP_FAIL and ESP_ERROR_CHECK() reboots the chip.

Here's what you need to do:

1. Correct the I2C address. In line 27 of main.c in example replace BMP280_I2C_ADDRESS_0 with BMP280_I2C_ADDRESS_1:

ESP_ERROR_CHECK(bmp280_init_desc(&dev, BMP280_I2C_ADDRESS_1, 0, SDA_GPIO, SCL_GPIO));

2. Replace GPIO numbers with yours in lines 12 and 13 of main.c

#define SDA_GPIO 5
#define SCL_GPIO 6

3. Compile and flash the example.

Still crashes. However, I found a bmp180 and set the GPIO ports and it worked perfectly! Thanks so very much for your answer!
