I dont know, but my power supply is only 5V and 800 mA. this power supply will supply my sensor and other circuits including( pic16f877a & max232). but the above circuit is not clear, and how can I calculate that it will be only 3mA?
Hello,
I have designed a power supply that will supply a 5V and 800mA. my sensor requires 2.7 V and 3mA maximum.
Do you have any idea how to divide the voltage into 2.7 volt and to limit the current to 3mA only.
I appreciate your kind assistance.
Thank you andre
I am trying to do like the above operation. But if I failed to detect one of the ACK, should I start the operation from the beginning?
I am trying to make my manual I2C code using MikroC.
Hello Dears
I have designed my Pic16f877a I2C to send many instructions. Also, to receive many bytes. I would like to know if I failed confirming receiving any of ACK, should I start the whole operation from the beginning, I mean should I start sending the instructions from the beginning.
Regards
Dear Jinzpaul4u
Dear Tahmid
I really appreciate your kind help.
I designed my MCU to work as master and the sensor as a slave. I have understood that when the master send a byte, the slave must send ACK bit. So, should I program my MCU to wait for every ACK.
Please correct me if I misunderstand.
