In case anyone needs such a memory, I found this other compatible code: M48T02/12: https://www.st.com/en/clocks-and-timers/m48t12.html > Description > The M48T02/12 TIMEKEEPER®RAM is a 2 Kb x 8 non-volatile static RAM...

This datasheet is **more** complete: https://www.st.com/resource/en/datasheet/m48t02.pdf This DS1642 memory can be read and written by TL866II Plus programmer, just select M48T12 memory (I asked developer to add DS1642 too, new...

I found a library that seems to have good accuracy for measuring low frequencies using Arduino, maybe this library can be used to calibrate in a basic way at least:...

I managed to test the memory, using logic analyzer (but the calibration must need more precision equipment, the reading was fluctuating in the thousandths of a Hz, 24MHz sampling). Need...

Hello, We can use the "Auxiliary I2C Bus": (Pag 26: https://www.invensense.com/wp-content/uploads/2015/02/MPU-6000-Datasheet1.pdf) > Auxiliary I2C Bus Modes of Operation: > --> I2C Master Mode: Allows the MPU-60X0 to directly access the...

Hello, Look this: [esp8266-sensor-mpu6050] https://github.com/rondawg369/esp8266-sensor-mpu6050

Hello, The sensor is very simple, just need to read the datasheet and the other document about the registers map. These documents are complements, frankly I think they should be...

Hello, Let's go to look at MPU6050_tockn.h file (/src/MPU6050_tockn.h path) the address below are of registers found at Register Map doc we can find here: https://www.invensense.com/wp-content/uploads/2015/02/MPU-6000-Register-Map1.pdf Register Map - Pag...

Hello, The datasheet can be found this way:
