Hi arjunbk09, In looking at UG585, the Zynq-7000 Technical Reference Manual, it appears that the I2C controller is capable of addressing in 7-bit or 10-bit mode as a bus master. To scan the bus for devices enter: $ sudo i2cdetect -r 0. The reference manual says you have to write I2C_CCR with PE clear so you may want to swap the order of those two statements. TXZ ファミリ I2Cインタフェース 2018-12-07 8 / 58 Rev. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). I had the same problem as you for 2 days until I realized that resetting the i2c peripheral and then turning off reset instantly does not actually reset anything. U-Boot Reference Manual Digi may make improvements and/or changes in this manual or in the probe to discover valid I2C chip addresses. The I2C_END_DETECT_INT_RAW interrupt request source bit is mentioned in chapter 11. 3 FDR Bits and Sub-Dividers FDR bit assignments vary among devices. 9 DTR/SLEEP_RQ/DIO8 Both Input Pinsleepcontrol Line/GPIO. LPC2148 Dev Board User Manual ARM7 LPC2148 is a 16/32 bit ARM7TDMI-S Core Microcontroller from Philips (NXP). This document is the hardware reference manual for the VEST VS5100 SOM (System-On-Module) based on the NXP’s i. C Compiler Reference Manual June 2008 viii Built-in-Functions 141. This device complies with Part 15 of the FCC Rules. The FT602 device uses the on-board I2C master interface exchange configuration information with the FIFO master. These can be installed with: $ sudo apt-get install i2c-tools. It provides complete information on how to use the memory and the peripherals of the STM32F411xC/E microcontroller. Following the I2C programming guideline in LS1021A Reference Manual Rev C. For more detailed information for the MPU-60X0 devices, please refer to the “MPU-6000 and MPU-6050.
