Hi sir, I am working with I2C in x-nucleo-nfc07a1 where ST25DV IC incorporated interfaced with Nucleo-WB55 board, what is the slave address(device address) for this?I am firmware engineer, I have I2C Scanning program wherePreviously, I work with Tem...
app_twi_perform() returns 0x03 == NRF_ERROR_INTERNAL.Reset board with button does not help.After Power Cycle can update EEPROM successfully.Accessing FTM buffer with proprietary smartphone app.
Hello Community, Is there a fast way to clear the EEPROM of ST25DV. for example, a fast API to clear the whole EEPROM, and how long it will take? I want to have the option to clear the memory when a special command is written through RF Thank you ver...
We are using M24LR64E for configuration and event logging, try to use password to protect configuration data area. In the user manual(DM00047008.pdf), in Figure 12 and Figure 13, the password address is 0900h, but in Table13, I2C byte address is 2048...
I have a microcircuit M24SR04-Y, on which I recorded information using the NFC.I need to read this information using i2c.I read the datasheet and understood the circuit of communication with the microcircuit.But I am a novice and without an example i...
Posted on May 07, 2018 at 00:51Hello, i have a STM8L Discovery board with a stm8l152C6T6 microcontroller. I'm currently trying to communicate with a M24LR04E (NFC) board through an I2C connection.I've done some tests using the 'generateStart' functi...
Posted on February 24, 2016 at 08:57Hi all, I'm using a M24SR memory connected by I2C bus to a Freescale M0 microcontroller. Given that the free space for the firmware is very little, I have problems integrating the ST library for reading and writin...
Posted on March 10, 2014 at 17:29Hi,I am sending this message because I am facing an issue using the M24LR16E-R.My i2c communication between my microcontroller and the M24LR16 chip works perfectly (I am able to read and write the entire memory multi...
Posted on January 23, 2014 at 16:29Hi,I wish to know please if using this memory is there any way to access, via RF, the information that I stored via I2C. Or is the information separated, via I2C (2048 bytes) and via RF (512 blocks of 32 bits) , wi...
