Dear expert,
I am new user to use MSP430(F2013) . It has many module function described on
IO like: TA0~2、CA0~x .
I want to know if I need to decode rs232 signal . I want to use timer to implement.
1.Do I need to select IO which have TAx function?
2.If question 1 is "yes" , then what's...
Dear expert,
I have a need to read the negative voltage . If there are any suggestions.
Please give me ideas .
Can ADC read the negative voltage ?
Very very thanks ~
sorry my describe unclearly.
the start value of counter depend on the first bit '1' of the bus.
if first bit 1 at bit 3 , then start counter value is 3
if next bit 1 at bit 6 , then second counter value is 6 ..... continue loop
very very thanks ~
Dear experts,
I want to design a counter which will depend on a input 8 bit bus .
if bus is "10011010" , my counter sequence is 1 ->3->4->7 ->1->3->4->7 loop .
if bus is "10000001" , counter sequence is 0->7->0->7 ... loop
My bus is random changed .
Would you please give me a advise or a...
ep2c8
Dear Sir,
I have something confused in FPGA design. Would you please give me any suggestion ?
My FPGA is CYCLONE II EP2C8-208
1. SDR SDRAM control :
May I always enable CKE and always disable DQM for saving my IOs ?
2. SPI serial flash :
- There is a "hold" pin , I need...
cyclone ii power altera linear regulator
Dear Sir,
would you please suggest me about Altera cyclone II
EP2C8Q208 Vccint 1.2V circuit ?
Is there any linear regulator could supply this voltage ?
Very very thanks your suggestions ~
Dear sir,
Does FPGA could setup IO to an open-drain and pull up to 5V for driveing
5V device ?
Or could you suggest me to implement it .
very thank you !
tmds lvds
Hi dear all,
I could see many LVDS repeater, fan out buffer and multiplexer ,
but I can't find these chips used on TMDS signal ......
Could you tell me the difference .
If I use LVDS repeater, fan out buffer and multiplexer on TMDS signal,
could or could not ?
very thanks ~
i2c cpld
Hi ,
I want to send serial eeprom data to CPLD/FPGA in I2C bus .
My component is AT24C16 and AT89s52 and FPGA
There are two way I could think of :
Way 1:So need to write a I2C HDL code let FPGA directly read AT24C16
Way 2:Use AT89s52 to read AT24C16 then write to FPGA by I2C bus...
Hi ,
I want to drive more devices , but many logic buffer speed is about 5ns
My source speed is 3.3V 160MHz
Could you suggest me any advise ?
very thanks~
Hello ~
Is there any one ever design this function ?
I use LVDS transmitter like ds90c385 to convert 28 bit lvcmos data
I want to duplicate it , who could suggest me how to design it ??
very very thanks~
DEAR ALL:
How can I switch the differential signal , like LVDS and TMDS high speed signal .
Because I have two or more source input,then I only have one receiver.
Is there any switch that I can use ?
Thanks very much
