Hi,
We designed our communication system of automation as CANBUS. But we forgot that string or long (more than 8 bytes) messages are rarely needed to send.
For example changing the IP address of a specific device.
So, we are planing to use both MCP2551 and MAX485 chips on the same line...
Hi,
I want to read only channel 1 data at single conversion mode. Datasheet says that the conversion data contains which channel was converted (CI - Channel Indicator bits).
I'm confused that if I dont send the channel information to read conversion result, all channel conversion data are sent...
Hi again. I have changed the circuit and the software in accordance with the product datasheet. EOC is checked every 32 bit spi reading if conversion is active. The BUSY interrupt gets logic high after the last SCK clock. (External SCK and single conversion, 3 wire SPI)
All pictures show the...
The frequency of SCK is 2 MHz.
The problem is shown in the picture. All things are on same position. But adc sends data like randomly.
Each groups are zoomed:
No change. But sometimes it give different values rondomly. I wonder if the problem is caused by PIC frequency. May it possible?
I had connected SDI pin to PIC and same problem was happened.
Hi,
I have a strange problem about LTC2440. Proteus simulation runs perfect, but the SDO pin of ltc2440 gives always logic high at real circuit. I watch the waveform on the scope and see same as this (Note: I draw short form of the wave 4 clock pulses instead of 8 bit).
SDO...
