My questions are;
- whether there are adjustments to be made to the I2C address scanner to make it find with this chip?
- whether I need or can control the address setting via the CSB and SD0 lines. ie. can I assume they are actually the AD0 and AD1 lines?
I ordered BMP280 temperature sensors and got similar looking boards labeled GY-B11-280 instead of BMP-280. The P is marked so it is not an E version with pressure - only temperature and humidity.
The chip is a Texas Instruments tmp461-KP. Datasheet at https://www.ti.com/lit/gpn/tmp461
I ran the following code and it usually says no I2C devices found but occasionally says 0x47; about 10-20 passes between reports. I note that 0x47 is not one of the addresses the chip is supposed to offer. The data sheet says 48-50.
The address is set via AD0 and AD1 on the chip. I tried pulling each and both of CSB and SD0 high but no change. (then tried a different sensor board in case I fried something)
The scan code used is interfacing-16x2-lcd-module-with-esp32-with-and-without-i2c/#Code_to_get_the_I2C_address
I bought a dozen of them.
Any help is appreciated.
